When pressurizing a car air conditioning compressor, the low pressure should be between 1.0 to 2.5 bar, and the high pressure should be between 15 to 18 bar. The steps for pressurizing a car air conditioning system are: 1. Set the remote control to cooling mode and turn on the air conditioning; 2. Check if the indoor unit is operating normally; 3. Verify if the outdoor compressor starts properly; 4. After normal startup, connect the refrigerant charging equipment to the low-pressure valve side port of the outdoor unit; 5. Measure pressure and add refrigerant; 6. Use soapy water to check for any leaks. The car air conditioning compressor is a key component of the car air conditioning refrigeration system, responsible for compressing and transporting refrigerant vapor. Car air conditioning compressors are divided into fixed displacement compressors and variable displacement compressors.

What to Do When the Car Air Conditioner Leaks Water into the Car?

Reasons for car air conditioner leaking water into the car: 1. Blocked drain pipe: Long-term use can cause the drain pipe to age, loosen, or bend, forming a wavy shape that leads to poor drainage and local blockages, causing water to leak into the car. Replace the drain pipe to fix the issue. 2. Clogged drain outlet: The outdoor drain outlet may be blocked by debris, preventing condensation water from draining. This can cause water to back up and eventually leak into the car. Clean the drain pipe to resolve the issue. 3. Improper installation: If the indoor unit is tilted excessively or the pipe direction is too high, water may not flow properly, leading to accumulation and eventual leakage into the car. Reinstall the unit to correct the problem.

What glue is used to repair a leaking car radiator?

For a leaking car radiator, a high-strength leak sealant can be used to stop the leak. Here is some relevant information: 1. Do not drive if the radiator is leaking: If the radiator lacks water or has too little, the engine will not receive sufficient cooling from water or antifreeze, leading to overheating, which can cause cylinder scuffing or bearing seizure, making the engine unable to start. 2. Insufficient coolant: A leaking radiator directly results in insufficient coolant, causing the engine temperature to rise excessively. This can lead to insufficient oil viscosity, preventing the formation of an oil film between friction surfaces and increasing wear. The pressure inside the engine cylinders becomes too high, leading to rough operation. Various mating components, especially aluminum ones, may experience thermal deformation.
