The air conditioner does not heat, how to add R410A refrigerant?

The cold winter has continued to cool down. Air conditioners have become an indispensable part of homes and offices. However, the heating effect of air conditioners is suddenly not good. How to add refrigerant if there is a lack of refrigerant? Get up and take a look!

The pressure of r410a is about 1.6 times higher than that of R22 refrigerant. Therefore, once the wrong operation occurs during the construction and after-sales service, a major accident may occur . When installing R410A refrigerant air conditioners, use R410A special tools and materials, and pay attention to safe operation.

(1) Before the operation, confirm the name of the air-conditioning refrigerant, and then perform different operations on different refrigerants. In the household air-conditioning using R410A refrigerant, you must not use R410A other than R410A refrigerant must not be used in air conditioners that use R22 refrigerant.

(2) If refrigerant leaks during operation, please ventilate in time.

(3) When installing and moving the air conditioner, please do not mix air other than R410A refrigerant into the air conditioner's refrigerant circulation pipeline. If non-condensable gas such as air is mixed in, it will cause abnormal high pressure in the refrigerant circulation pipeline, which is the main cause of rupture and cracks in the circulation pipeline.

(4) After the installation work is completed, please carefully confirm that there is no leakage of refrigerant. If the refrigerant leaks indoors, it will form toxic gas once it comes into contact with electric sparks from electric fans, heaters, electric stoves and other appliances.

(5) When installing one-to-multiple air conditioners, because the amount of enclosed refrigerant is relatively large, especially in small rooms, even if the refrigerant leaks, it will The concentration cannot exceed the specified value. Otherwise, it will cause hypoxia.

(6) When installing and moving the air conditioner, please implement it reliably in accordance with the requirements of the manual. When the installation is poor, it will cause abnormal operation of the refrigerant circulation pipeline, water leakage, electric shock, fire and other phenomena.

(7) Please never modify the air conditioner privately, and ask professionals to repair it. Improper repairs can also cause water leakage, electric shock, and fire.

Friendly reminder: For non-professional personnel, please do not disassemble and install by yourself to avoid refrigerant leakage, which may cause personal and property safety.
