SHY33MC4-U SHX33SC4-U SHW33TC4-USHZ33LC2-S Brand New Hitachi Air Conditioner Compressor Compressors are used in a wide range of applications, mainly in equipment such as air water heaters, domestic air conditioning, cold storage, central air conditioning, industrial cooling and other equipment.02 Construction
1. Disconnect the power supply
2.Disassemble the compressor and check the old compressor.
3. Nitrogen cleaning system, step by step, disassemble the filter with nitrogen from the radiator inlet blowing in, radiator outlet discharge, and then from the filter inlet blowing in, from the compressor back to the gas pipe discharge, repeated cleaning several times
4.Installation of new compression, new filter welding
5.Pressure with nitrogen, 20Mpa pressure leakage check for 30 minutes (please do not use the compressor pressure)
6. Check the circuit to replace the damaged parts, check the power supply and control lines.
7.Clean the radiator
8.Discharge nitrogen, evacuate for 30 minutes.
9. add the same type of refrigerant, ordinary air conditioning with the vast majority of R22 refrigerant 10. power commissioning, testing the compressor current and voltage, the normal pressure of refrigerant high pressure 1.7Mpa, low pressure 0.45Mpa, refrigerant charge simulation for 0.7kg / pi (10 pi - 30 pi) construction, such as the side of the ground before the construction to do the above steps, to ensure that to extend the life of the compressor to play a greater capacity and power savings. The above steps before construction will ensure that the life of the compressor will be prolonged.
