1. There is something wrong with the air conditioner capillary. The capillary network simulates the mechanism of veins and human capillaries, and consists of capillaries with an outer diameter of 3.5 to 5.0 mm (with a wall thickness of about 0.9 mm) and main water supply and return pipe with an outer diameter of 20 mm (with a wall thickness of 2 mm or 2.3 mm). Solution: Replacing the capillary tube can solve the problem that the air conditioner does not heat.
2. The air conditioner four-way valve leaks. Four-way valve is an indispensable component in refrigeration equipment. Its working principle is that when the solenoid valve coil is in the power-off state, the pilot slide valve is driven by the right compression spring to move to the left, and the high-pressure gas enters the capillary tube and then enters the right piston cavity. Solution: replacing the four-way valve can solve the problem that the air conditioner does not heat.
3. There is too much dust in the air filter of the air conditioner, and the air outlets of the internal and external machines are blocked by foreign objects. The function of the filter screen is to absorb the dust in the air. If there is too much dust and it is not cleaned up in time, it will hinder the air circulation, resulting in a decrease in the air output at the air outlet, which will lead to the lack of heating capacity in the machine. Solution: cleaning the filter can solve the problem that the air conditioner does not heat.
4. The air conditioner is short of fluorine. Fluorine deficiency in air conditioning can not only cool, but also cause heating effect. At present, most air conditioners are heat pump air conditioners or heat pump plus auxiliary electric heating air conditioners. The working principle of these two air conditioners is to absorb heat from outdoor air when Freon evaporates. Lack of fluorine will cause heat absorption and will not work normally. Solution: Ask professionals to add fluoride to solve the problem that the air conditioner does not heat.

Precautions for air conditioning use:
1, don't switch frequently. There is a thermostat in the air conditioner. When the indoor temperature reaches a fixed temperature, the air conditioner will automatically adjust whether it needs to run. Frequent switching on and off not only saves electricity, but also damages the machine.
2. When you feel that the air conditioner is not ideal, you should consult the instruction manual, analyze whether it is caused by improper use, and correct it after finding out the reason.
