What is the method of adding refrigerant to the sprinkler air conditioning system?Now our means of transportation are basically cars, but as the temperature rises in summer, we cannot do without the air conditioner in the car, but can the air conditioner that has not been turned on for a long time still maintain a good cooling effect? If your air conditioner is not working well, it may be time to replace the refrigerant. The same is true for our sprinkler. In summer, the high temperature sprinkler operation is frequent, and the sprinkler air conditioning system is particularly important for the driver. Let’s take a look at how to add refrigerant to the air conditioner of the sprinkler.

As a sprinkler driver, we all know that after the long winter, the air conditioner is basically in a dormant state. During this period, a large number of microorganisms and harmful bacteria will grow in the air conditioner, the sprinkler air conditioning system which not only makes the sprinkler air conditioning system emit an unpleasant odor when it is working, but also There is a direct hazard to the health of the sprinkler driver. Therefore, when the sprinkler air conditioner is just used, it is best to sterilize and deodorize the air conditioner system. This work can be done at the nearest sprinkler chassis repair factory, or you can purchase a special spray for sterilization and deodorization.

Install a branch pipe pressure gauge on the sprinkler air conditioning system, connect one end of the green hose to the middle of the pressure gauge, the sprinkler air conditioning system and the other end to a vacuum pump, and then vacuumize.

Install the refrigerant tank. Install the filling tank to the branch pressure gauge, completely close the valves on the pressure side and high pressure side of the branch pressure gauge, install the sprinkler air conditioning system to the green filling hose in the middle of the branch pressure gauge, sprinkler air conditioning system and turn the handle clockwise until the needle valve is cooling. Drill a hole in the sprinkler air conditioning system, turn the handle counterclockwise to exit the needle valve, sprinkler air conditioning system press the air purge valve of the branch air pressure gauge, and release the sprinkler air conditioning system until the sprinkler air conditioning system is released from the valve.

Fill sprinkler air conditioning system from the high pressure side. When the engine is not working, open the high pressure side valve and add refrigerant until the pressure value of the low pressure gauge is about 0.98MPA. After filling, close the valve.

Check for air leaks and use an electronic leak detector to detect air leaks in the system.

Fill the refrigerant from the low pressure side, close the high pressure side valve, start the engine and run the air conditioner, open the branch pressure gauge, and add the specified amount of refrigerant.

Precautions for the use of sprinkler air conditioners:

When using the air conditioner for the sprinkler truck, do not adjust the temperature of the air conditioner too low. If the temperature is adjusted too low, the temperature difference will affect your health. Generally, when using the sprinkler air conditioning system, the temperature difference between the inside and outside of the car should be controlled at about 8 degrees.

When the air conditioner is turned on in the car, the driver of the sprinkler truck should not smoke in the car. If smoking, the ventilation control of the air conditioner should be adjusted to the outer circulation gear.

It is very comfortable to sleep with the sprinkler air conditioning system on. In fact, this is very harmful to the human body.
