People are often unable to withstand the hot weather this summer. At this time, fans and air conditioning are needed to help people cool down. Generally speaking, because the temperature in the south is much higher than that in the north, almost every family has to have air conditioning. Air conditioning is relatively to fan, it can automatically adjust temperature, choose suitable for your comfortable temperature, in people's eyes, air conditioning refrigeration effect, than fan. Probably because air conditioning can adjust temperature, and fan only uses, his own, speed of rotation, to cause wind, help you to heat.
What is a good air conditioning, only its cooling effect, good he is a good air conditioning. If his effect is not good, my aunt after buying home, it can not provide you, the cold feeling makes you can not spend the hot summer. And relatively speaking, the price of air conditioning is not low. If, let you calculate, you will find an air conditioner, almost you can buy a room fan. Many people, buy home air conditioning, will appear, not refrigeration, often to this time, people do not know what is caused.
The reason why the air conditioner doesn't work
One of the reasons why the air conditioner doesn't work well: Freon is not enough
When the ambient temperature is about 35 ℃, 1. Low pressure 0.45mp2; high pressure: 2.5MP; 3. Static pressure: 1.1-1.2mp.
This is normal, usually in the use of three to four years of old air conditioning. Air conditioning is not completely uncooled, but the effect of refrigeration has declined. This is because old air conditioners use freon as refrigerant, and they will evaporate for a long time. So the user just to the normal air conditioning maintenance point to add a point. In addition, improper installation will not be ruled out, which causes Freon leakage and problems of the machine itself.
The second reason why the air conditioner doesn't work: the power supply voltage is not enough
The normal starting voltage of air conditioner is 220v+-10%. In the power supply system with phase voltage of 220V and line voltage of 380V, almost all compressors above 200V can be started. When the value is above 180V, 70-80% can be started, and only individual can start when the value is above 160V. I did the experiment myself. It is almost impossible to start below 160V. According to experience, the starting voltage of compressor is reliable when the voltage is above 190V.
The third reason why the air conditioner doesn't work: the power of the air conditioner is not enough
The general selection principle is: 150-250w / m2 for refrigeration and 250-350w / m2 for heating. In addition, the space height, level orientation, sealing performance and residential population should be considered comprehensively.
The fourth reason why the air conditioner doesn't work: the outside environment temperature is too high
There is a common saying: when the outdoor unit is in the environment above 43 degrees, most air conditioners are difficult to transfer the indoor heat to the outdoor, which leads to no refrigeration.
The fifth reason why the air conditioner doesn't work: the air conditioner doesn't clean and maintain for a long time
If air conditioning can operate normally and does not affect human health, it is also necessary to extend its life as much as possible. Obviously, it is impossible to ignore it once it is bought and installed. Outdoor unit is exposed to outdoor, easy to absorb dust and debris, and it will affect the heat dissipation performance of the machine for a long time, which will lead to the reduction of cooling effect of air conditioning. And indoor machine is related to human health, long time not clean, will breed bacteria, pollution air, make people sick.
The sixth reason why the air conditioner doesn't work: the copper pipe connecting the indoor unit and the outdoor unit is too long.
The maximum allowable length of the connecting pipe of the air conditioner shall not exceed 8 meters, 1.5-2 pieces shall not exceed 10 meters, and more than 2 pieces shall not exceed 15 meters. The height difference between indoor and outdoor units shall not exceed 5 meters.
Although air conditioning can help people to spend the hot summer, people will not feel very hot when they are at home, but we must remember that when using air conditioning, the air conditioner should not be too low, not in order to pursue cool, but the temperature is very low, so it is easy to make yourself catch a cold and continue. When you are very cool in the house, you usually go out and it is very hot outside The temperature of the fork can easily catch a cold. Moreover, it's easy to get sick if you blow the air conditioner for a long time. Therefore, although the air conditioner has many advantages, it must be used properly. Don't overdo it, let alone turn on the air conditioner every day for the whole summer.
