Reasons why the air conditioner does not heat

Air conditioning is a common household appliance that we use frequently in our daily lives. In daily life, the main functions of air conditioning are cooling, heating, and dehumidification. Air conditioners also have many faults. Many air conditioners will not heat. The main reason why the air conditioner does not heat is that there are problems with some air conditioning capillaries and some one-way valves, that is, factors inside the air conditioner, which can all be solved.

In daily life, the air conditioner does not heat because the outdoor temperature is too low. The outdoor temperature is too low, which will cause some air conditioners to not work normally. Generally, the variable frequency air conditioner below zero degrees generally stays at minus fifteen degrees and cannot heat normally. There are also some reasons why the air conditioner does not heat.

Reasons why the air conditioner does not heat: There is a problem with the air conditioner capillary or one-way valve

Capillary: The capillary network simulates the mechanism of leaf veins and human capillaries. It is composed of capillaries with an outer diameter of 3.5-5.0mm (wall thickness of about 0.9mm) and supply and return water trunk pipes with an outer diameter of 20mm (wall thickness of 2mm or 2.3mm).

One-way valve: also known as check valve or non-return valve. Used in hydraulic systems to prevent reverse flow of oil, or in pneumatic systems to prevent reverse flow of compressed air.

What to do if the air conditioner does not heat due to this reason: Replacing the capillary tube or the one-way valve can solve the problem of the air conditioner not heating.

2 Reasons why the air conditioner does not heat: the outdoor temperature is too low.

Too low outdoor temperature will cause the air conditioner to not work properly. Generally, when the outdoor temperature is below zero degrees, the variable frequency air conditioner can no longer heat normally when the outdoor temperature is around minus 15 degrees. So it is possible that the outdoor temperature is too low and the air conditioner cannot defrost and cannot heat.

What to do if the air conditioner does not heat due to this reason: Use tools to clean the frost on the air conditioner to solve the problem of the air conditioner not heating.

3. Reasons why the air conditioner does not heat: the air conditioner four-way valve is leaking.

Four-way valve: A hydraulic valve term, which is a control valve with four oil ports. The 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 moves left under the drive of the right compression spring, and the high-pressure gas enters the capillary tube ① and then enters the right end piston chamber. On the other hand, the gas in the left end piston chamber is discharged. Due to the pressure difference at both ends of the piston, the piston and the main slide valve move left, so that the exhaust pipe is connected to the outdoor unit pipe, and the other two pipes are connected to form a refrigeration cycle.

The above are the reasons why the air conditioner does not heat. The main reasons are some problems with the air conditioning capillaries and some one-way valves, which are factors inside the air conditioner. Therefore, we must pay attention to the reasons why the air conditioner does not heat in daily life. There are also many reasons. In daily life, we can consult some professionals for maintenance.
