How to do Chang 'an Yidong air conditioner without refrigeration?

The most common failure points of uncooled air conditioners are:

The refrigerant in the air conditioning system leaked out, resulting in no refrigerant, so the air conditioner did not cool.

You can check some components in the air conditioning system, such as pipes, air conditioning pumps, condensers, evaporation boxes, etc. Damage and cause refrigerant leakage. There is also an inspection method, which can add fluorescent agent at the same time as refrigerant. After the vehicle has been used for one week, check the air conditioning system with a special fluorescent lamp. If there is a leak, it will light up, indicating that this part is damaged.

The air conditioning pump is damaged internally, which causes the refrigeration effect to fail to start. Generally, there will be abnormal sound when the air conditioning pump is damaged. So check the air conditioning pump. If it is damaged, it needs to be replaced.

The condenser fins in the air conditioning system are too dirty, which leads to the high pressure and temperature of the air conditioning system. In order to protect the air conditioning system, the air conditioning water pump stops working, so the air conditioner does not cool. You can use a high-pressure water gun to clean the condenser fins, and then use a high-pressure air gun to dry them.
