Cold room refrigeration piston compressor can adopt multi-unit parallel design for large cold storage to realize staged energy regulation. It can adapt to large fluctuating heat load of large freezer and preservation storage. xiteliduo Source factory of refrigeration supplies cold room refrigeration piston compressor, and provides parallel unit system design scheme for large cold storage projects.
Product application characteristics: Cold room refrigeration piston compressor for parallel system is mainly semi-hermetic type. Multiple compressors are connected to shared oil separator, condenser and liquid supply pipeline. Oil balance pipeline is equipped to keep consistent oil level of each crankcase and prevent oil migration among units. Each compressor has independent protection module and control loop. The control system can start or stop single compressor automatically according to real-time heat load. When heat load is low, only one or two units run; when heat load peaks, all units work together. Models for parallel system include 10HP,15HP,20HP piston refrigeration compressor. It supports R404A refrigerant for low-temperature freezer cold storage. Every compressor passes strict pressure holding and continuous running test before delivery. Vibration control and noise reduction design reduce mutual interference between parallel units. The factory can provide matched electric control cabinet scheme for multi-units parallel system.
Application fields & working scenarios: Large cold storage piston refrigeration compressor parallel system is suitable for large food freezing warehouse, large agricultural product preservation warehouse, large seafood cold storage and centralized low-temperature storage center. Such projects have large storage volume and obvious load fluctuation, especially in goods inbound peak period. Many cold storage general contractors will search large piston refrigeration compressor for large cold storage for large-scale cold storage bidding projects. Large cold storage projects in Zhejiang industrial belt often adopt multi-piston parallel scheme instead of single large capacity unit to improve system reliability. If one compressor fails, other units can still keep cold storage running to avoid total cargo loss.
Engineering application case: A large agricultural product logistics park in Shaoxing built a 2800㎡ multi-functional cold storage, including fruit preservation area and meat freezing area. The freezing area requires -18℃ constant temperature. The project adopted parallel scheme of four sets of 20HP cold room refrigeration piston compressors supplied by xiteliduo Source factory of refrigeration. The system is equipped with oil balance pipeline and independent safety protection for each unit. The control system automatically adjusts running quantity of compressors according to warehouse temperature and heat load. During goods inbound peak season, four units run together; in off-peak period, only 1~2 units work. After project delivery, the freezing zone maintains stable -18℃. Even if one unit needs maintenance, the rest units can keep warehouse temperature within safe range without mass goods loss. The project team compared the difference between piston refrigeration compressor and screw machine. The parallel piston scheme has lower risk of complete shutdown, convenient maintenance of single unit and lower spare parts cost, which fits the demand of large logistics cold storage.
Parallel piston compressor system needs reasonable pipeline design and oil balance control. Poor oil balance design will cause oil shortage failure of individual compressor. xiteliduo Source factory of refrigeration can provide cold room refrigeration piston compressor and parallel system technical consulting service. When designing large cold storage, heat load calculation should consider door opening frequency, goods temperature and local maximum ambient temperature. Regular inspection of oil balance pipeline and oil separator is required during operation. Users should record running status of each compressor separately, find out units with abnormal parameters in advance and arrange maintenance plan.
