Air conditioning is a kind of common household appliances that we often use in our daily life. In daily life, there are many common functions of refrigeration and heating, which can remove moisture. Air conditioning also has a lot of failures. Many air conditioners will have some reasons for not heating. The main reason why air conditioning does not heat is that there are problems with some air conditioning capillary tubes and some one-way valves, that is, the internal factors of air conditioning can be solved.
In daily life, the air conditioner does not heat up. Because the outdoor temperature is too low, some air conditioners can not work normally. Generally speaking, the frequency conversion air conditioner below zero usually stays at 15 below zero, which can not make normal heating. There are also some internal reasons for the air conditioner not heating.
The reason why the air conditioner doesn't heat: there is something wrong with the capillary or check valve of the air conditioner
Capillary: the capillary network simulates the mechanism of leaf vein and human capillary. It is composed of capillary tubes with an outer diameter of 3.5-5.0 mm (wall thickness of about 0.9 mm) and a main water supply and return pipe with an outer diameter of 20 mm (wall thickness of 2 mm or 2.3 mm).
Check valve: also known as check valve or check valve. It is used to prevent reverse flow of oil flow in hydraulic system or compressed air reverse flow in pneumatic system.
How to do if the air conditioner does not heat up due to this reason: replace the capillary tube or one-way valve to solve the problem.
The reason why the air conditioner doesn't heat: the outdoor temperature is too low
If the outdoor temperature is too low, the air conditioner can not work normally. Generally, the outdoor temperature is below zero, and the outdoor temperature of variable frequency air conditioner is about 15 below zero. Therefore, it is possible that the outdoor temperature is too low, the air conditioner can not defrost and the air conditioner can not heat.
What to do if the air conditioner does not heat up due to this reason: clean the frost on the air conditioner with tools to solve the problem.
The reason why the air conditioner doesn't heat up: air leakage of air conditioning four-way valve
Four way valve: a hydraulic valve term for a control valve with four ports. The four-way valve is an indispensable part of refrigeration equipment. Its working principle is that when the solenoid valve coil is in the power-off state, the pilot slide valve moves to the left under the drive of the right compression spring, and the high-pressure gas enters into the right piston chamber after entering the capillary tube. On the other hand, the gas in the left piston chamber is discharged. Due to the pressure difference between the two ends of the piston, the piston and the main slide valve move to the left, making the exhaust pipe and outdoor unit move to the left The connecting pipes are connected and the other two connecting pipes are connected to form a refrigeration cycle.
The above is the reason why the air conditioner does not heat up. The main reason is that there are problems with some air conditioning capillaries and some one-way valves, which is the internal factors of the air conditioner. Therefore, we must pay attention to the reasons for the non heating of the air conditioner in our daily life. In our daily life, we can consult some professional personnel for maintenance.
