Causes and solutions of air conditioning not heating

Causes and solutions of air conditioning not heating 　　The air conditioner has the functions of cooling and heating. Heating in winter and cooling in summer. Life is called a comfortable one. However, why is the air conditioner not heating? In the cold winter, the air conditioner is turned on for heating, but the cold wind blows out, which makes people tremble more. This is not great. Let's take a look at the analysis and solution of the reason that the air conditioner does not heat. 　　 Why is the air conditioner not heating? Cause analysis and solution of air-conditioning without heating 　　 Reason 1: The temperature difference is large, and the heating effect of the air conditioner is not obvious If the temperature difference is too large, the heating effect of the air conditioner will not be obvious, especially in the north. When the outdoor temperature is below 0 degrees, the outdoor unit of the air conditioner will frost immediately. At this time, the air conditioner needs 8-12 minutes to "defrost" "The heating effect in a short time is not very obvious, you need to wait for a while. 　　 Reason two: The room is too large, which makes the air conditioning heating not obvious If the space in the room is too large, and the weather is too cold, the heat of an air conditioner is not enough to dissipate quickly. The effect is definitely not good. At this time, it is necessary to open two more to achieve the ideal. effect. 　　 Cause three: There is too much dust at the air outlet, which causes the air conditioning heating effect to be insignificant 　　 When the air filter at the outlet of the air conditioner has serious dust accumulation, it will block the air outlet and reduce the amount of air, resulting in an ineffective heating effect. At this time, you need to clean the air filter and then install it. 　　 Reason four: the voltage is too low, resulting in ineffective heating effect of air conditioner 　　 If it is the peak period of electricity consumption, it may cause the voltage to be too low or the voltage to be unstable. If the voltage may cause the air conditioner to not work properly, the air conditioning heating effect is not obvious. When the voltage is normal, the air conditioner can resume normal operation. 　　 Reason five: lack of freon leads to air conditioning not heating 　　 Today's air conditioners on the market basically use heat pump type or heat pump plus auxiliary electric heating type. The lack of freon will cause the air conditioner to not heat. At this time, you need to ask after-sales service personnel to check the freon. 　　 Reason 6: Failure of check valve and four-way valve leads to no heating of air conditioner As mentioned in the fifth point above, the air conditioners on the market are basically heat pump type or heat pump plus auxiliary electric heating type. If the check valve used to switch the refrigerant cycle fails, the resistance of the refrigeration system will be reduced. If the condenser cannot obtain heat, there will be insufficient heating of the air conditioner. In addition, the four-way valve string gas will also reduce the heating function. At this time, the check valve or the four-way valve can be replaced. 　　 Why is the air conditioner not heating? The above is the analysis and solution of the reason why the air conditioner does not heat. I hope it will be helpful to everyone.
