1, the method of adding fluorine at the low pressure end: first, the manifold pressure gauge is connected with the compressor and the refrigeration tank; Open the refrigerant tank, loosen the nut on the manifold pressure gauge to feed the hose until you hear the refrigerant steam flow, then tighten the nut bankDischarge air into the hose; Open the low pressure manual valve to allow refrigerant to enter the refrigeration system.
2, the method of adding fluorine at the low pressure end: First, the manifold pressure gauge is connected with the compressor and the refrigeration tank; Open the refrigerant tank, loosen the nut of the middle injection hose on the manifold pressure gauge until the sound of 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.
3. Method of filling refrigerant with automotive high voltage regulating terminal Empty step: 1. After the system is pumped into the air, turn off the high and low pressure on the manifold pressure gauge manuallyA valve. Connect one end of the middle hose to the connector of the refrigerant tank injection valve. Turn the manual valve on the high pressure side to the fully open position and turn the refrigerant tank upside down. Inject a specified amount of liquid refrigerant from the high pressure side.
[Pacific Auto network] two methods. The high pressure end is injected with refrigerant, and the low pressure end is injected with fluorine. When the system is vacuumed, close the high and low pressure manual valves on the manifold pressure gauge. When the system is vacuumed, close the high and low pressure manual valves on the manifold pressure gauge. Connect one end of the middle hose toConnection of refrigerant tank injection valve.

Turn the manual valve on the high pressure side to the fully open position and turn the refrigerant tank upside down. Inject a specified amount of liquid refrigerant from the high pressure side.
Open the manual valve on the manifold pressure gauge to allow refrigerant to continue to enter the refrigeration system until the specified amount of charge is reached. After the specified amount of refrigerant is filled, observe through the sight glass. If no air bubbles are detected, no air bubbles are detectedIf the refrigerant is excessive, set the engine speed to 2000r/min and the fan air volume to the highest level. For example, the low pressure side pressure in the system should be 0.147~0.192MPa, and the high pressure side pressure should be 37~67MPa. Hope to adopt.
There are two ways to add refrigerant to automotive air conditioning, one is to add refrigerant at the high pressure end, and the other is to add fluorine at the low pressure end. Before filling, vacuum the system and close the high and low pressure manual valves on the manifold pressure gauge. Refrigerant is a working fluid used to transfer heat energy in refrigeration and air conditioning systems, which can make the air becomeCool and comfortable.
The steps for adding refrigerant to the automobile air conditioner are as follows: After the system is vacuumed, close the high and low pressure manual valves on the manifold pressure gauge. Connect one end of the middle hose to the refrigerant tank injection valve connector, open the refrigerant tank valve, and then unscrew the nut of the manifold gauge hose to allow gas to escape for a few minutes before tightening. Unscrew the manual valve on the high pressure side and inject the specified amount of liquid refrigerant.
1, this is both magnetic wireless charger noneLine car charging refrigeration , but also the radiator, at the same time to solve the two problems of heat dissipation and endurance. Wireless charging semiconductor cooling radiator, in addition to having efficient wireless car charging cooling active cooling capacity, but also has wireless charging function, you can heat the mobile phone at the same time can also charge the mobile phone.
2, in summary, the one plus liquid cooled radiator magnetic wireless charging is undoubtedly a technology and practical innovation, it with excellent heat dissipation performance and wireless charging function, to solve the user in the fast-paced life of many troubles.rong> : Then remove the outer machine, you can see that there are two copper pipes inside, the big copper pipe is called the low pressure pipe, the small copper pipe is called the high pressure pipe, you should open the nuts under the small copper pipe. 3 Wireless car charging refrigeration : Then it is connected to the snow type table, look at its pressure, generally about 5 kg.
When the air conditioner is out of service, fluoridate from the fluoridated place. When the system pressure reaches 0.8~0.9Mpa, it is suitable to let the air conditioner run and cool for 30 minutes, and carefully check. (1) Pressure measurement Low pressure pressure is 0.35~0.55Mpa. If it is high, add more wireless car charging refrigeration , if less, add less.
Pressure: Open the cooling mode of the air conditioner, connect the refrigerant cylinder, always pay attention to the pressure gauge, when 5-5 pressure is added, stop the pressure, start the air conditioner to see whether the refrigeration is restored. If there is no recovery, consider the existence of fluorine leakage, with soapy water in the pipe connection and pipe, fluorine try, there are bubbles indicate leakage, after repair, in the fluorine to 5-5 pressure can be.
Connect the filling tube: will coolThe filling tube is connected to the filling valve. Make sure the connector is tightly connected to the valve to avoid leaks. Open the charging valve: Slowly open the charging valve according to the manufacturer's instructions to allow refrigerant to enter the air conditioning system. At the same time, the manometer is observed to monitor the refrigerant pressure during the charging process. Control cooling dose: According to the requirements of the air conditioning system and the manufacturer's recommendations, control the amount of refrigerant charged.
1, when the car air conditioning does not refrigerate after the restart and refrigeration, it is likely that there is a problem with the air conditioning liquid storage drying tank. The drying tank in the air conditioning refrigeration system is mainly responsible for absorbing water in the refrigerant to prevent excessive water from causing the cooling capacity to decline. If there is a problem with the drying tank, it may lead to poor cooling. At this time, it is necessary to check whether the drying tank is working properly, and if the drying tank has problems, it may need to be replaced.
2, the air-conditioning switch circuit is faulty or the air-conditioning pump electromagnetic clutch is faulty. If it happens more than once, it is recommended to arrive in timeRepair shop repair.
3, ① It is recommended to observe whether the cooling fan rotates when the cabin air conditioner is cooling. If it does not run, please maintain it as soon as possible. ② Observe whether there is any alarm symbol on the instrument when the air conditioner is not refrigerated? If there is a need to solve the problem of refrigeration to no refrigeration, whether the air volume of the blower has a significant change, if there is a significant change, it may be that your evaporator frosts, you need to check whether the evaporator temperature sensor is open and so on.
4, there is a problem with the air conditioning liquid storage drying tank. There is a drying tank in the refrigeration system of the car air conditioner, and its main task is absorptionThe moisture in the refrigerant and the prevention of excessive moisture in the refrigerant leading to a decrease in the cooling capacity. When the desiccant in the drying tank is saturated, the water can not be filtered out again.
5, the compressor drive belt of the car air conditioning is relaxed, and the phenomenon of slipping will occur when the compressor works, which will reduce the transmission efficiency, resulting in a decrease in the speed of the car compressor. Because the delivery of compressed refrigerant has decreased, it will lead to the phenomenon of non-cooling of automobile air conditioning.
6, car air conditioning is not refrigerated reason 2: air conditioning flap damage air conditioning flap motor damage This failure is relatively rare,It's not like it hasn't been there. If there is a problem with the flip motor, the flip motor is generally in the lower part of the instrument panel, which belongs to the main switch of the air conditioner tuyere, it is broken means that the switch is good, even if the air conditioner can cool the cold air can only drill out from the seam, which is the meaning of drinking poison to quench thirst.
