Cold storage parallel units can be widely used in different industries such as food processing, quick freezing and refrigeration, medicine, chemical industry and military scientific research. Generally, compressors can use various refrigerants such as R22, R404A, R507A, 134a, etc. Depending on the application, the evaporation temperature can be from +10°C to -50°C.
Under the control of PLC or special controller, the parallel unit can always keep the compressor in the most efficient state by adjusting the number of compressors to match the changing cooling demand, so as to achieve the purpose of maximum energy saving.
Compared with the conventional single unit, the cold storage parallel unit has obvious advantages:
1. Energy saving
According to the design principle of the parallel unit, through the automatic adjustment of the PLC computer controller, the parallel unit can realize the complete automatic matching of the cooling capacity and the heat load. Compared with the energy consumption can be greatly saved.
2. Advanced technology
The intelligent control logic design makes the configuration of the refrigeration system and the electric control part more optimized, and the characteristics of the whole machine are more prominent, ensuring the uniform wear of each compressor and the best working condition of the system. The modular design enables the unit to meet the needs of customers to the greatest extent, and each module forms its own system, which is more convenient to control.
3. Reliable performance
The main components of the parallel unit system usually use world-renowned brand products, and the electronic control adopts Siemens Schneider and other famous brand products, with stable and reliable operation performance. Because the parallel unit automatically balances the running time of each compressor, the compressor life can be extended by more than 30%.
4. Compact structure and reasonable layout
The compressor, oil separator, oil accumulator, liquid accumulator, etc. are integrated into one rack, which greatly reduces the floor space of the machine room. The general computer room covers an area equivalent to 1/4 of that of a single-machine scattered computer room. The carefully designed unit is easy to operate and maintain, the center of gravity is stable, and vibration is reduced.
