A)Cold storage refrigeration units;
B)High reliability and safe operating;
C)Remote control;
D)Compact structure
Advantages of cold storage refrigerating rerigeration condensing units:
High-efficient and energy saving Highly automatic performance
1. Distinctive Power-control by level
High efficiency and energy conservation can be achieved through realizing the best power control according to the load variation since the unit of several compressors can obtain a multilevel output-power combination.
2 High reliability
Even in case of malfunction of one compressor, normal operation will not be affected since the other ones can still keep refrigerating.
3 Safety operation
Equipped with complete security systems for such cases as high pressure, low pressure, oil pressure differential, over load and overheating, etc., the unit can guarantee a normal operation even under severe working conditions like over high or low temperature.
Remote control: Remote monitoring can be achieved with the controller specially used for parallel compressor unit. So you can take control of all equipment in the cold storage just staying in your office.
4 Space saving
Compact design significantly saves the space for both installation and maintenance, which makes the unit be easily set in front of or behind the house, or on the roof, with no need for a special room or operator on duty.
5 Economical operation
The most economical operation can be ensured throughout since the optimum number of working units can be obtained by automatically switching on and off the compressors according to the pressure value which is generated by the pressure sensor based on temperature requirements. And the number of working compressors and the operation time can also be determined according to the heat load of the cold storage. For example, several compressors will work together when the house encounters an intensive stock; While only one will be used for all rooms when there's a relatively small storage or winter with smaller heat load.
