Closing the doors and windows and opening the air conditioner will cause the indoor c

  The weather was sultry and humid after entering the night.Only by working together can we turn camper air conditioning The value of the play out, the development of the supply market needs. https://puremind.com/product-category/puremind-air-conditioner/rv-air-conditioner/

  

  The frequency of air conditioning is increasing.

  

  Hot summer day

  

  Is it advisable to stay in an air-conditioned room for a long time?

  

  Do I need to open the window to ventilate the air conditioner?

  

  The answer is coming ◎

  

  Turning on the air conditioner should not close the doors and windows.

  

  A set of experiments will show you.

  

  Many people have been in air-conditioned rooms for a long time.

  

  I will feel dizzy and sleepy.

  

  This may be that the indoor carbon dioxide concentration exceeds the standard.

  

  Experts said

  

  National standard of indoor carbon dioxide concentration

  

  The general requirement is below 1000ppm.

  

  For shopping malls, schools and other densely populated places

  

  Generally, the concentration of carbon dioxide is required to be below 1500ppm.

  

  When the indoor carbon dioxide concentration reaches 2000ppm

  

  The human body often feels dizzy and uncomfortable.

  

  There are only two or three people in the family.

  

  Why does the concentration of carbon dioxide exceed the standard?

  

  Two experimenters are in a 13-square-meter bedroom

  

  Close the doors and windows and turn on the air conditioner.

  

  By placing a good observer

  

  Real-time observation of indoor carbon dioxide concentration changes

  

  Over time

  

  The concentration of carbon dioxide keeps rising.

  

  Just half an hour.

  

  It has already exceeded 1500ppm.

  

  Experts said

  

  For the home environment

  

  This concentration has exceeded the standard

  

  after an hour

  

  The concentration of carbon dioxide in the air

  

  More than 2000ppm

  

  And it’s rising

  

  The experimenter opened the window for ventilation.

  

  After 15 minutes.

  

  Indoor carbon dioxide concentration

  

  Slowly dropped below 1000ppm.

  

  It can be seen that the doors and windows are closed and the air conditioner is turned on for 1 hour.

  

  It may cause the indoor carbon dioxide concentration to exceed the standard.

  

  If you sleep in this environment for one night,

  

  It is very likely that lack of oxygen will bring health risks.

  

  It is recommended to turn on the air conditioner.

  

  Open the window properly to get some air.

  

  For families that are inconvenient to open windows

  

  Consider purchasing a new fan.

  

  Instead of window ventilation

  

  Air-conditioned rooms should not stay long.

  

  Beware of “air conditioning disease”

  

  It is hot and hot in summer.

  

  Stay in an air-conditioned room for a long time

  

  Not only dizziness, headache

  

  It may also induce “air conditioning disease”

  

  Knowledge of small science popularization

  

  ”Air-conditioning disease” is a series of diseases induced by long-term use of air conditioning. When using air conditioning, the space is relatively closed, the air is not circulating, pathogenic microorganisms are easy to breed, and the temperature difference between indoor and outdoor is large, so the body is not well adapted, so a series of symptoms will appear.

  

  Abdominal pain and diarrhea

  

  The stomach and intestines are very sensitive to the stimulation of temperature.

  

  Excessive indoor and outdoor temperature difference

  

  Accelerated gastrointestinal peristalsis

  

  Cause digestive dysfunction

  

  Cause abdominal pain and diarrhea

  

  catch a cold and have a fever

  

  Enter the room with low temperature from the hot outdoor.

  

  Easy to catch a cold and cough.

  

  Even induce asthma and pneumonia.

  

  Serious illness

  

  neck shoulder lumbocrural pain

  

  Thin clothes in summer

  

  Shoulder, knee, waist, etc.

  

  Exposed to the cool breeze for a long time

  

  It is easy to cause symptoms such as joint and muscle pain.

  

  It is easy to cause cervical spondylosis and scapulohumeral periarthritis.

  

  cardiac infarction

  

  From low temperature indoor to high temperature outdoor.

  

  Switch like this

  

  Will make blood vessels suddenly contract and expand.

  

  Repeated fluctuation of blood pressure may induce myocardial infarction.

  

  For the elderly with fragile blood vessels,

  

  be highly dangerous

  

  How to blow air conditioning healthily?

  

  Pay attention to these points!

  

  Air conditioning should be cleaned regularly.

  

  Whether it’s central air conditioning

  

  Or a stand-alone air conditioner at home

  

  It should be cleaned before use.

  

  It is recommended to clean it once every 1~2 months after use.

  

  Window ventilation is essential.

  

  Turn on the air conditioner

  

  Attention should be paid to frequent ventilation.

  

  It is recommended that every 2~3 hours.

  

  Just ventilate the room once.

  

  Ventilation for 10 to 15 minutes each time.

  

  Air conditioning wind blows upward.

  

  The temperature should not be too low.

  

  Cold air will stimulate sweat pores to contract suddenly.

  

  It is easy to cause dizziness, headache, runny nose,

  

  Symptoms such as joint pain.

  

  It is suggested that the temperature of air conditioner should be adjusted to 26≧

  

  The temperature difference between indoor and outdoor should not exceed 7≧

  

  When the air conditioner is turned on, the cold air sinks.

  

  So the wind had better blow upward.

  

  Avoid cold air blowing directly on your body.

  

  Drink more warm water.

  

  To prevent water loss from the body

  

  Causes dry skin and itchy throat.

  

  Drink plenty of warm water.

  

  Drink chrysanthemum tea, etc

  

  Eat more fresh fruits rich in vitamins.

Just want to hold the air conditioner Please remember these cold knowledge

  Improper use of air conditioningIf we can practice these points, commercial heating and cooling Will be unique, become a leader in the industry, and keep moving forward. https://puremind.com/product-category/puremind-air-conditioner/commercial-air-conditioner/

  

  Not only will it increase electricity consumption,

  

  It may even affect your health.

  

  Today, follow the Shanghai Health Promotion Center.

  

  Let’s learn the “cold knowledge” of air conditioning use ~

  

  Don’t “open and close for a while”

  

  I wonder if you have had such an experience?

  

  Caught in the strange circle of air conditioning turning on cold and turning off hot, repeated operation is always “cutting suitable”; Or go out and get a courier, thinking that it is more energy-saving to turn off the air conditioner first.

  

  In fact, often this behavior of frequently starting the air conditioner increases the power consumption and is not conducive to the maintenance of the air conditioner.

  

  Studies have proved that air conditioning “turns on and off for a while” does not actually save electricity. Therefore, if you only go out for a short time, you don’t have to turn off the air conditioner and turn it on again.

  

  Pay attention to “humidity” and “temperature”

  

  The muggy air has a high humidity, so it is uncomfortable to adjust the temperature. At this time, try to turn on the “dehumidification mode” after air conditioning refrigeration, and the air will become more refreshing and comfortable.

  

  If you need to stay in an air-conditioned room for a long time, remember to drink water properly to avoid the loss of water.

  

  Practice has proved that it is most appropriate to control the indoor and outdoor temperature difference at 6-8≧, mainly to reduce the burden on the thermoregulation center and avoid the symptoms of dizziness, headache and dry skin and mucosa. Therefore, the air conditioning temperature is set at 26 to 28≧.

  

  Don’t sweat and rush into the air-conditioned room.

  

  In hot summer, it is easy to sweat when you move a little and bask in the sun. Do you just want to rush into the air-conditioned room? At this time, you should be careful that the disease will come to you.

  

  For the general population, sudden cold and heat are easy to catch a cold, have a fever and have diarrhea; It is even more dangerous for patients with hypertension and coronary heart disease.

  

  The cardiovascular system in the original thermal environment is in a state of relaxation, and the sudden cooling air after entering the air-conditioned room makes the blood vessels contract urgently, which is prone to dangerous situations such as myocardial infarction.

  

  Therefore, don’t rush into the air-conditioned room after sweating, let the sweat collect first, or wipe your body with a dry towel first. When the air conditioner is just turned on, it should not be adjusted to a too low temperature, and at the same time, it should avoid cold air blowing directly on the head, neck and waist and abdomen.

  

  Do a good job cleaning

  

  The cleaning problem of air conditioning is often easily overlooked, and the bacteria hidden in it will take advantage of the opportunity to cause “air conditioning disease.”

  

  Legionella, which lurks in the daily artificial water environment, is such a pathogen. Water contaminated by bacteria can be inhaled by human body in the form of aerosol. After people are infected with Legionella, there will be symptoms similar to pneumonia, such as high fever, chills, fatigue, muscle pain, etc., which may even be life-threatening.

  

  The air conditioning system is the main “hiding point” of Legionella, so it is necessary to clean and disinfect the air conditioning; If it is a central air conditioner, the deposited cooling tower water should be replaced and the attached “dirty things” should be removed in time. Don’t forget to clean the casing and filter screen after the “air conditioning season”.

  

  In addition, it is recommended to open the window for ventilation every 2-3 hours to ensure the cleanliness of indoor air.

Internet services in Cote d_Ivoire gradually resume after 24 hours of interruption

In today’s market background, cnc turning service Still maintain a strong sales data, and constantly beat the competitors in front of us. https://www.ultirapid.com/services/cnc-machining/

Abidjan, March 15th: Cote d’Ivoire’s network communication services began to gradually resume on the 15th after 24 hours of widespread interruption across the country due to the rupture of submarine optical cables.

A major network operator in Cote d’Ivoire said the problem that caused the interconnection outage has been partially resolved and the resolution is continuing.

Four submarine optical cables serving West Africa suddenly broke on the 14th, causing the interruption of fixed and mobile network services provided by many telecom operators and Internet service providers in Cote d’Ivoire. It is reported that this incident affected more than ten African countries including Cote d’Ivoire, Liberia, Benin, Ghana, and Burkina Faso.

Cote d’Ivoire’s Minister of Digital Transformation and Digitalization Konat said in a statement on the 15th that the interruption of the national network in Cote d’Ivoire is an unprecedented special event, and the government is taking measures to restore network connectivity within the next 48 hours to minimize the impact on the economy and people’s daily lives.

According to officials from the Ministry of Digital Transformation and Digitalization of Cote d’Ivoire, the two major network operators in Cote d’Ivoire have switched to a cable that is still operating normally to gradually restore network communication services. (Reporter Zhang Jian)

The air conditioner at home is easy to blow away the wealth.

  With the development of society and the improvement of people’s living conditions, air conditioning has become a necessity in people’s lives. But you know what? The placement of air conditioners is also said to be feng shui. The improper placement of air conditioners will actually block the wealth of the family. So how to place the air conditioner? What are the precautions for air conditioning placement? Let’s take a look.More importantly, put Puremind Industrial Chillers It is imperative for us to make thorough analysis and maximize its social function. https://puremind.com/

  

  Air conditioning is a typical product of modern houses, and there is no introduction about air conditioning in any ancient geomantic books. However, air conditioning has obvious influence on the geomantic omen of Yangzhai because of its function of air supply and temperature regulation. So, are there some feng shui precautions for air conditioning, a household appliance that only appeared in modern houses? Let’s sum up some questions about air conditioning feng shui.

  

  1. The air outlet of the air conditioner should not face the door.

  

  It has been mentioned many times that “storing wind and gathering gas” is the basic principle of Feng Shui. One of the major characteristics of air conditioners is that they can spray air to adjust the indoor temperature. These spouted air currents themselves cause direct disturbance to the gas field of the house. The gas field is too strong, and the air flow and the air flow entering the gate will have an impact, which will directly destroy the stability of the gas field of the house. Not to mention gathering wealth, the popularity will be washed away by the gas field of the house.

  

  2. Don’t hang the air conditioner on the sofa or bedside.

  

  The wall-mounted air conditioner itself is particularly similar to the beam in shape. As we all know, there can’t be a cross beam above the sofa or bedside, otherwise there will be a problem of the cross beam topping. In fact, air conditioners should also avoid the situation of topping. Moreover, the air conditioner itself has cold air injection, which goes straight to the head or body, and the impact is more direct. Therefore, remind everyone that when choosing the hanging position of air conditioner, try to avoid pressing against people’s body parts.

  

  Don’t blow the air conditioner directly on people.

  

  In the first article, we emphasize that air conditioning can’t blow on people’s heads, which is mainly from the perspective of air conditioning topping. In fact, even other parts of the body, try not to be blown directly by the air conditioner. Although the air conditioner is cool, it is very easy to catch a cold, stroke or backache, which directly affects people’s health. You can manually change the air outlet direction of the air conditioner to avoid being directly blown.

  

  4. Air conditioner should not blow the dining table directly.

  

  Experienced friends know that long-term use of air conditioners will absorb a lot of dust and germs. Therefore, for air conditioners that are often used, if the filter screen cannot be cleaned on time, it will also cause the accumulation of foul air in the house. If the air conditioner blows air directly on the dining table, these foul gases and germs can easily be directly adsorbed on our food, which will have an unnecessary impact on our health.

  

  5. Don’t blow the air conditioner directly.

  

  Some friends will install air conditioning in the kitchen because of the large space in the kitchen. But when installing air conditioning in the kitchen, don’t put the air conditioner directly on the stove mouth, especially on the flame. The reason is very simple. This kind of direct gas field disturbance will not only make the flame unstable and cause safety hazards, but also symbolize the hostess in the image. The direct air conditioning will also have unnecessary effects on the hostess’s own body. So remind everyone, if you have to install air conditioning in the kitchen, don’t let the air conditioning mouth directly face the stove mouth.

  

  Location of air conditioner

  

  Fans must not be placed in the financial position.

  

  If the air conditioner happens to be in the financial position, it will blow away your fortune. The financial position pays attention to hiding the wind and gathering gas, and should be quiet and not moving. They are also fast-running appliances, so they will transfer the airflow from the outside to the home, and plants, fish and the like should be used to stimulate the financial position. Fans can only blow away wealth, which is very unfavorable to home wealth and will soon appear. Therefore, we must pay attention to the fact that the fan must not be placed in the financial position.

  

  The fan must not be placed in a fierce position.

  

  But the fan is a dynamic substance, which is basically a product of making brake gas. Especially when it is placed in a fierce position, it will provoke fierceness, which is really bad.

  

  The cold air that doesn’t start is not enough for feng shui effect.

  

  Air-conditioning emits cold and frozen gas, so it belongs to gold in the five elements, which is the same as refrigerator. If the summer is long and the opening time is more than half a year or more, air conditioning will have a great influence on home feng shui, but it should be noted that the air conditioning that is not started is basically not enough to achieve feng shui effect.

  

  They belong to gold, and the way to find out where to put them is very simple. Whoever wants gold from a family member, putting air conditioning in the position where the member belongs is the most favorable feng shui decoration. If the father wants gold, put it in the northwest, if the mother wants gold, put it in the southwest. The wind released by the air conditioner will create a geomantic magnetic field. Adjusting the tuyere to the upper side is more beneficial to home feng shui, because in the wind direction, it represents the airflow swirling down from the ceiling and the airflow blowing, which is the best form.

  

  Its decoration should be based on the needs of the five elements of family members, and can also be used in conjunction with the lucky time of the year. Find out the bad side and the financial side. If the air conditioner is located in the bad side, the air conditioner on this side should be turned on as little as possible, and feng shui objects should be placed to release two black and five yellow.

  

  kitchen

  

  The kitchen stove is where the whole family can fill their stomachs. If the air conditioner is directly on the stove fire, it will make the stove fire weak, which will damage the energy of the food in cooking, thus affecting the health of the housing people. In addition, the stove fire is also representative, so it has a great impact on the life of couples.

  

  Correction method

  

  Don’t install air conditioner if you can, but if you must, blow the wind towards the ceiling or sideways as much as possible.

  

  dining room

  

  When air conditioners are used for a period of time, dust will inevitably accumulate. Therefore, if the air conditioners in the dining room blow directly on the dining table, it is very likely that the dust will fall into the hot food with the wind, and of course, it is easier to cool the delicious meals on the table. Therefore, it is best not to place the air conditioners in the dining room above or near the dining table.

  

  bedroom

  

  When people sleep, the sweat pores are wide open and the respiratory system is relatively unguarded. Therefore, if the air conditioner blows directly, it will not only make people feel unwell and catch a cold, but also attract evil spirits more easily.

  

  Correction method

  

  Raise the air outlet upward, or slightly open the window in the room to evenly blow the cold air.

  

  study

  

  Air conditioning makes people cool, so it has the function of condensing thinking and improving reading concentration. If we can move the air conditioner in the study to the north and use the energy of air conditioning operation, it will drive Wenchang to good luck, which will certainly benefit candidates or people who study knowledge. Of course, remember not to blow the air outlet toward your face or head, lest your head be unbearable before you finish reading the book.

  

  sitting room

  

  Air-conditioning is a fast-running electrical appliance, so it will turn the outside air flow into the home, and the southwest of the Year of the Monkey will treat diseases. Therefore, if the air-conditioning at home is placed in this position, it will definitely make the family suffer from illness and illness this year.

  

  Correction method

  

  Use a small fan to change the wind direction opposite the air conditioner. In addition, in the Year of the Dog, peach blossoms dominate the northeast, Wenchang dominates the west, and the northwest dominates the financial position. If you want to strengthen the above fortune, you can also move the air conditioner to this position, which has a strong effect on luck and transshipment.

  

  Popularization of feng shui knowledge of air conditioning

  

  Nowadays, people’s living conditions are improving day by day, and the popularization of air conditioning has extended to every household. Air conditioning is warm in winter and cool in summer, which not only improves people’s quality of life, but also brings more warmth and comfort to people. Then, from the perspective of geomantic omen, how to make the layout of air conditioners more in line with the principles of geomantic omen, so as to prosper in people’s career, wealth, marriage and health, and improve people’s quality of life?

  

  First, the current three types of home air conditioning

  

  At present, home air conditioners can be generally divided into wall-mounted air conditioners, cabinet air conditioners and central air conditioners. According to the principles of geomantic omen that “there is evil spirit when visible” and “there is an image that should respond”, it is considered that there are obvious differences between the “existing form” and “supply cooling and heating mode” of these three types of air conditioners in home, so their functions and functions in home geomantic omen will be different. That is to say, different types of home air conditioning layout in the same location may have different feng shui consequences.

  

  Second, the interpretation of three key locations of home air conditioning layout

  

  1. Is air conditioning suitable for financial position?

  

  It is believed that, first of all, cabinet air conditioners are not suitable for financial position. As we know, financial position is the place where the breath in the home gathers, and cabinet air conditioners will occupy the financial position because of its tall body, and then “squeeze” the wealth; Secondly, central air-conditioning is not suitable for the financial position. Generally speaking, the wind of central air-conditioning blows vertically downward, while the financial position in geomantic omen is generally quiet and motionless. If central air-conditioning is installed above the financial position, its airflow will blow straight down, and the financial position will be exhausted, which is actually an image of money not gathering; Finally, it is considered that the wall-mounted air conditioner is very suitable for the financial position, because it just overcomes the shortcomings of the cabinet air conditioner, which is too large and the air flow in the central space is straight down. Moreover, the wall-mounted air conditioner also has the advantages of high and basic lateral air exhaust. Although it is in the financial position, its air flow is discharged straight ahead, so that while strengthening the air flow in the house, it also maintains the relatively stable and gentle replacement of the air in the financial position, and then uses the air in the financial position to keep fresh.

  

  2. Is the air conditioner suitable for Wenchang?

  

  It is believed that, generally speaking, all three types of home air conditioners are suitable for layout in Wenchang. Because Wenchang represents school, career, official transport, fame, reputation and influence in geomantic numerology, the layout of home air conditioners in Wenchang will definitely enhance the corresponding energy, and then play the role of prosperity. Then, why can the layout of home air conditioning improve the corresponding energy in Wenchang? Because Wenchang’s general five elements attribute is fire, which is often said to be the main fire. The bright wood fire is the most prosperous image in geomantic numerology, while the five elements of air conditioning discharged from air conditioning are aquatic wood, and the five elements of heating discharged are wood fire, while heating is generally used in winter, and water is also used in winter. Therefore, this forms the image of aquatic wood and wood fire, and its breath gathers in fire, which means Wen and Wenchang; Even more, because of the existence of water, the situation of fire flourishing and wood burning will never be formed, which is also the principle of the five elements of “one (water) four (wood) and the palace master Wang Wen” in Xuankong Feng Shui.

  

  3. Is the air conditioner suitable for layout at Taiji point?

  

  Taiji point is the center of gravity and center point in the home. It is considered that among the three types of home air conditioners, the central air conditioner is the most suitable layout in Taiji. The central air conditioning is arranged at Taiji point. In the cold winter, warm air comes from the sky, which makes the whole home full of warmth. In the hot summer, the cold wind falls from the “sky”, making the whole home full of sweetness and coolness. As we know, geomantic omen pays attention to the word “image”, and this image is the image of enjoying the grace of heaven and meeting your career. However, wall-mounted air conditioners and cabinet air conditioners are difficult to “hide” and are limited by installation conditions, drainage conditions and other factors, so it is really difficult to achieve the feng shui effect of central air conditioners.

  

  Third, the basic feng shui knowledge of home air conditioning layout

  

  Warm reminder

  

  In the layout of home air-conditioning, the direction of its air outlet is particularly important. Generally speaking, the air outlet of home air-conditioning should not face the places where people are active frequently, mainly the “three places” such as seats, beds and stoves. This is the problem of different effects produced by “actively receiving feng shui energy” and “passively receiving feng shui energy” in the geomantic omen of the Ark. That is to say, when the air outlet of the air conditioner is facing the “three places”, people can only passively receive the feng shui energy, and when the feng shui energy exceeds a “degree” that people can bear, it will naturally do harm to people; However, when the air-conditioning geomantic omen is not directly opposite to the “three positions”, people can fully play their active role by actively receiving the geomantic omen energy, and generally there will be no harm caused by receiving the geomantic omen energy too much.

New study_ Antarctic ice shelf melt water much higher than previously predicted

Besides, we can’t ignore. cnc milling services It has injected new vitality into the development of the industry and has far-reaching significance for activating the market. https://www.ultirapid.com/services/cnc-machining/

Beijing, July 17: An international study recently found that in January, when the Antarctic summer temperature is the highest, 57% of the melt water on the Antarctic ice shelf exists in the form of snow and mud. However, under normal circumstances, regional climate change models do not include This part of the melt water is calculated. This means that the amount of melt water on the Antarctic ice shelf is much higher than previously predicted.

Researchers from the University of Cambridge and other institutions in the United Kingdom published an article in the latest issue of Nature Geoscience that they trained machine learning models to analyze the monthly surface melt water records of 57 Antarctic continental ice shelves between 2013 and 2021. As well as mapping the snow and mud of the Antarctic ice shelf, it was found that in January, when the temperature in the Antarctic summer was the highest, 57% of the melt water on the Antarctic ice shelf existed in the form of snow mud, which is, snow soaked in water. The rest of the meltwater exists in surface ponds and lakes.

Researchers said that people usually use satellite images to map meltwater, but from the images, only meltwater lakes, etc. can be identified with the naked eye, and snow and mud are difficult to identify because it looks like the shadows of clouds. Machine learning models can use more satellite information such as light wavelengths to determine which areas are named snow and mud, making it possible to more accurately measure the amount of water melted on the ice shelf.

The study found that in the five major ice shelf areas, the amount of water melted on the Antarctic ice shelf caused by surface melt water was 28 times higher than predicted by standard climate models.

The surface melting of the Antarctic ice shelf mainly occurs in the summer of the southern hemisphere. Whether it is slush or melt water existing in surface ponds or lakes, it will affect the stability of the ice shelf and lead to sea level rise.
