Water-cooled screw chiller high quality

The cooling capacity of water-cooled screw chiller is larger than that of ordinary scroll chiller, and high-quality and efficient shell and tube evaporator is adopted. Hanzhong screw compressor: semi sealed screw compressor: high efficiency, low noise and stable operation. Built in oil separator: smaller volume and better effect

The evaporator has higher heat exchange efficiency and higher energy efficiency than dry evaporator. The same refrigeration unit is slightly smaller than the dry type.

Disadvantages:

1. It is necessary to add liquid level control device or overheating control device to ensure that the refrigerant flowing into the evaporator can maintain the liquid level at an appropriate level.

2. The price of liquid level control device or overheat control device is relatively expensive, the maintenance and adjustment are very troublesome, and the adaptability of the unit to changes is poor.

3. If the liquid level of the refrigerant in the evaporator decreases, the refrigerant oil compatible with the refrigerant in the evaporator is not easy to return to the compressor. This is the loss of the compressor and may directly lead to the combustion of the compressor.

4. If the level of refrigerant in the evaporator rises, the refrigerant will enter the compressor in liquid form, resulting in liquid compression, which will also cause the compressor to burn out.

5. The filling amount of refrigerant and refrigerant oil in the whole system is more than twice that of dry type, and the maintenance cost will increase in the future.

6. Because the overflow of evaporator is very troublesome, the quality of refrigerant oil is very high. It must be ensured that refrigerant oil works under very high quality. After use for a period of time, the refrigerant oil will gradually thicken, so it is very difficult to return the oil and must be replaced immediately. The service life is shorter than that of dry evaporator, which greatly increases the operation cost.

7. When the chilled water flows in the copper pipe of the evaporator, it is easy to condense due to the low temperature, resulting in the rupture of the copper pipe.
