R404a brand screw type parallel compressor racks for apple and carrot cold storage

1. Because of a huge demand difference between seasons for refrigerating capacity, the unit must have a high level control for capacity, so that the unit can keep running under high efficiency mode. The average parallel unit efficiency, according to different refrigeration system is 30% higher than single compressor unit.
2. Using multiple compressor parallel units can provide a multiple energy level control, the refrigeration output can be dynamically allocated more smoothly according to actual situation.
3. With high efficiency oil separator, only a small amount of lubricating oil enters the system, this largely brings up the heat exchanging efficiency.
4. The PLC controller monitors running compressors quantity, it maintains a maximum use rate even when only parts of the compressors are functioning.
5. PLC controller can be set with the best running curve (maximum & minimum power comsuption), to same as much electricity as possible.
6. With “modularized design” the risk during construction can be largely reduced, construction period can be shortened, improve the product quality controllability.
