What's the matter with the air conditioner not cooling in summer? What are the solutions for air con

In hot summer, it's the time when air conditioning is needed to play a role. But do you feel that the refrigeration effect of every time you turn on the air conditioning is particularly poor, or it's common in the fire box? What's the matter with no cooling of air conditioning in summer? What are the solutions for no cooling of air conditioning?

Reason 1: insufficient freon

This is a normal situation. Generally, it occurs in the old air conditioner that has been used for three to four years. The air conditioner is not completely uncooled, but the refrigeration effect is not good enough. This is because the old air conditioner uses freon as the refrigerant, which will evaporate if used for a long time. In addition, it does not rule out the problems of Freon leakage and the machine itself caused by improper installation.

What to do: adding snow seeds can solve the problem of air conditioning uncooled (this article is exclusively arranged by WYH, editor of sihai.com. If you need to reprint, please indicate the source and source. Related article link: http://www.4hw.com.cn/life/jujia.html)

Cause 2 - insufficient supply voltage

The power supply voltage is not stable and often can not reach the normal voltage, especially when the peak power consumption is relatively easy to occur this phenomenon. Of course, this kind of problem can't be solved by a skilled air conditioner maintenance technician. We must solve the problem by providing stable voltage.

What to do: keep the normal power supply voltage or choose variable frequency air conditioner.

Cause 3 - insufficient power of air conditioner

This is also one of the common reasons for non refrigeration, but there are many reasons for this kind of non refrigeration, such as: small power air-conditioning pipe large area room, and some although the air-conditioning power and room area seem to match, but because the room is relatively not closed (such as doors and windows open), or there is a heating source in the room (such as more computers) of course, the glass room west sun is also One of the heat sources, etc.

What to do: to match the cooling capacity required by the power space of the air conditioner; to change the conditions of the use environment; to increase the airtightness of the use environment; to reduce the heating source in the use environment of the air conditioner and so on.

Cause 4 - high ambient temperature

This kind of non refrigeration is common in our outdoor unit installed in a relatively closed space or the temperature around the outdoor unit is too high, so it is extremely easy to cause the air conditioner not to be refrigerated because the small space where the outdoor unit is located has no air circulation, resulting in the heat from the radiator can not flow away; there is also a common saying that when the outdoor temperature is more than 43 degrees, most of the air conditioners are not refrigerated It is difficult for digital air conditioner to transfer the indoor heat to the outdoor through the radiator of the outdoor unit, which will also cause the air conditioner to be uncooled.

What to do: change the use environment of the outdoor unit (move away from the high temperature environment or make the air around the outdoor unit easier to circulate), and pay attention to the correct and reasonable location when installing the air conditioner.

Cause 5 - the air conditioner is not cleaned and maintained for a long time

Buying an air conditioner doesn't mean you have no worries. Because the outdoor unit is installed outdoors, after a long time of use, it will absorb a lot of dust, garbage and other dirt on the radiator, so that the radiator's cooling effect is poor, making the air conditioner uncooled. In addition, the long time of air conditioner maintenance will make the room air unsanitary, more prone to air conditioning disease, increase and reduce the power consumption Air conditioning service life, etc.

Cause 6 - the copper pipe between outdoor unit and indoor unit is too long

Some air conditioners are too long because of the need of installation or unreasonable installation, so the low heat transfer efficiency will also cause the air conditioner not to refrigerate.

What to do: try to reduce the length of the copper pipe between the outdoor unit and the indoor unit of the air conditioner
