1, first start the car, and turn on the AC switch, turn on the blower to the maximum, wait for three minutes to put the fluoride tube into the fluoride nozzle. The refrigerant into the fluoride nozzle, and always pay attention to the pressure in the air conditioning tube, remember not more and not less! The air conditioning system and the air conditioning tube are connected, so the pressure in the tube represents the pressure of the air conditioning system, and the amount of refrigerant and the outside temperature directly affect the air conditioning systemThe pressure value.
2, automotive air conditioning fluorine how to fill freon automotive air conditioning fluorine filling method is: high pressure end filling, suitable for leakage detection, vacuum filling, note that this method must not open the compressor, the engine is stopped, and the refrigerant tank requires upside down; Low pressure end filling, filling is gas, characterized by slow filling speed, usually suitable for use in the case of replenishing refrigerant.
3, vacuum: after the pipeline connection is correct, and the refrigerant recovery and filling machine boot self-test is completed, you can begin to vacuum the automobile air conditioning. Add refrigerant: until the end of vacuumingIs displayed before adding refrigerant. According to the maximum capacity of refrigerant marked by the vehicle air conditioning, the filling capacity, time and type are set on the refrigerant recovery and filling machine, and the refrigerant recovery and filling machine can automatically start adding refrigerant after confirming.
4, car air conditioning with freon is one of the more common operations in car maintenance. There are two ways to add freon to automobile air conditioning: emptying and filling refrigerant. The method of venting is to use the table valve to vent the refrigerant to the outside. The procedure is as follows: Install the manifold pressure gauge. If the compressor has a maintenance valve, open the handle first. Turn off manifold pressure gauge high. Low manual valve.Refrigerant method? 1, the low pressure end of adding fluorine wireless refrigeration car charging method: First, the manifold pressure gauge is connected with the compressor and the refrigeration tank Wireless refrigeration car charging ; Open the refrigerant tank wireless refrigeration car charger , loosen the nut of the manifold pressure gauge to inject the hose until the refrigerant steam flow is heard, and then tighten the nut to discharge the air injected into the hose; Open the low pressure manual valve to allow refrigerant to enter the refrigeration system.
2, first willStart the car, turn on the AC switch, turn on the blower to the maximum, and wait for three minutes to put the fluoride tube into the fluoride nozzle. The refrigerant into the fluoride nozzle, and always pay attention to the pressure in the air conditioning tube, remember not more and not less wireless refrigeration car charger! The air conditioning system and the air conditioning tube are connected, so the pressure in the tube represents the pressure of the air conditioning system, and the amount of refrigerant and the external temperature directly affect the pressure value in the air conditioning system.
3, the timing filling method is a method of filling according to the rated filling amount of the air conditioner by using the filling device. Selective cylinderWhen the refrigerant reaches the selected scale, open the corresponding valve to let the refrigerant flow into the measuring cylinder. When the refrigerant reaches the selected scale, open the charging valve to let the refrigerant in the measuring cylinder flow into the refrigeration system. This method is accurate and suitable for on-site repair.
1, the car air conditioning can not add fluorine may be because the operation method is wrong, the internal air pressure is too large, the air conditioning outside the machine is not started, the air conditioning computer board problem, the remote control receiver problem, the air conditioning compressor is bad, some old models needFluorine can only be added by adjusting the fluoridation port.
2, because the air conditioning system is blocked or leaked, can not add refrigerant. The precautions for adding refrigerant to the car air are as follows: First use the machine to pressurize: Before adding fluorine, first use the pressurizing/vacuumizing machine to pressurize and check for leaks. Generally, it is not necessary to look at the negative pressure value of 3 minutes. When the time is up, tighten the switch of the low pressure meter, and you can fill the fluorine tank.
3, the car air conditioning can not be filled with refrigerant may be due to system blockage. An air conditioning system is a sophisticated system consisting of many components, such as compressors, condensers, evaporators, expansion valves, and throttle valvesAs well as multiple evaporators and controllers. The failure of any one component can cause the system to malfunction. Therefore, when the air conditioner cannot be filled with refrigerant, the first task is to check the components, identify potential sources of blockage and repair.
4, there is a blockage in the car air conditioning system is the cause of the refrigerant can not be added.
5, the reason that the car air conditioning refrigerant can not be added may be that there is a blockage in the air conditioning system. Refrigerant plays a vital role in automotive air conditioning, which uses its own physical changes to take away the heat in the car. Under high pressure, the refrigerant changes to a liquid state,It also gives off heat.
6, the car air conditioning can not be filled with refrigerant, the main reason is that there is a blockage in the air conditioning system. Only after the blockage problem is successfully checked and solved, the air conditioner refrigerant can be normally filled. Refrigerant, also known as refrigerant, plays a role in transferring heat energy and producing freezing effect in refrigeration and air conditioning systems.
