Cooling Efficiency Low-pressure Applications scroll Compressors

High quality R407C Copeland scroll compressor ZR310KCE-TWD-522

Some description as following：

Lack of refrigerant will reduce the amount of refrigerant provided to the evaporator, resulting in high evaporating temperature and high temperature of refrigerant vapor sucked in by the compressor, that is, high superheat, which will cause the compressor motor coil to overheat and cause overheat protection.

In the hot summer, the ambient temperature is too high. When the lack of refrigerant in the system is not too much, it is difficult to judge by the current of the compressor and the pressure measured by the system. On the contrary, it is easy to overfill. At this time, the temperature of the compressor discharge pipe can be measured. When the temperature is normal, it is about 20℃ higher than the saturation temperature corresponding to the discharge pressure at this time. If it is lower than this value, it means that there is too much refrigerant. If it is higher than this value, it means that the refrigerant is too much. insufficient.

The characteristics of scroll refrigeration compressors are as follows, and their characteristics are also the constantly pursued goals of air-conditioning compressor manufacturing technology.

1.The pressure difference between the two adjacent chambers is small, and the gas leakage is small.

2.the torque variation range is small, and the vibration is small.

3.There is no clearance volume, so there is no expansion process that causes the gas transmission coefficient to drop.

4. no suction, exhaust valve, high efficiency, high reliability, low noise.

5.Because of the gas bearing mechanism, it is allowed to compress with liquid.

6.The inner cavity of the casing is an exhaust chamber, which reduces the suction preheating and improves the gas transmission coefficient of the compressor.

7.The machining accuracy of the vortex body shape line is very high, and special precision machining equipment must be used.
