Low temperature piston refrigeration compressor belongs to enhanced piston refrigeration compressor. It adopts optimized cylinder and valve plate structure to adapt to high compression ratio low-temperature working environment, serving quick-freezing and deep freezer cold storage. xiteliduo Source factory of refrigeration produces low-temperature piston compressor for cold storage, providing professional refrigeration host and system optimization solution for quick-freezing engineering projects.
Product application characteristics: Low temperature piston refrigeration compressor optimizes internal flow channel and compression structure to bear high compression ratio required by low-temperature cold storage. It mainly adopts semi-hermetic structure for convenient maintenance. Models range from 5HP to 20HP, supporting R404A refrigerant which is widely used in low-temperature cold storage. The unit is equipped with oil pressure difference protection, high and low pressure protection and exhaust temperature protection. It can monitor the running state under continuous high compression ratio working condition. Special low-temperature lubricating oil is matched. The oil circuit is optimized to guarantee normal oil supply even under low suction temperature. Before delivery, low-temperature simulation test is carried out to verify cooling capacity and stability under low evaporation temperature. Shock absorption base reduces vibration transmission. Parallel connection is available for large quick-freezing cold storage to increase total cooling capacity. The shell can be equipped with crankcase heating belt as standard configuration to prevent refrigerant migration in low-temperature environment.
Application fields & working scenarios: Low temperature piston refrigeration compressor is mainly used in quick-freezing cold storage, meat deep freezer cold storage, seafood freezer cold storage and other working conditions requiring temperature below -18℃. Quick-freezing cold storage needs fast cooling rate, so the compressor must maintain stable cooling capacity under high compression ratio. Large quick-freezing production lines usually adopt multiple low-temperature piston refrigeration compressors in parallel. Small quick-freezing workshops select 5HP~10HP low-temperature piston models. Cold storage engineering contractors will search low-temperature piston refrigeration compressor when undertaking deep freezing projects. Many food processing factories in Zhejiang industrial belt select low-temperature piston compressor when building new quick-freezing workshops.
Engineering application case: A seafood processing factory in Shengzhou, Zhejiang built a 360㎡ quick-freezing cold storage for quick-freezing shrimp products. It requires the product core temperature to drop to -20℃ within 3.5 hours. The factory cooperated with xiteliduo Source factory of refrigeration to design refrigeration system. After heat load calculation, two sets of 10HP low-temperature semi-hermetic piston refrigeration compressors were selected, R404A refrigerant. The system adopted oil balance pipeline and crankcase heating belt. In construction stage, pipeline slope and liquid separator were configured to prevent liquid refrigerant entering compressor. Vacuum pumping, leak detection and refrigerant filling were finished step by step during commissioning. Suction superheat was controlled within 7K~10K. After operation, the cold storage can finish quick-freezing of batch seafood products as required. Even in summer high temperature season, the compressor can maintain stable cooling capacity. After 2.5 years of continuous operation, only regular oil replacement and filter maintenance were carried out without core component damage. The project engineer learned about piston refrigeration compressor working principle, so daily operation parameters can be recorded to judge unit health status.
Low temperature piston refrigeration compressor cannot replace medium-temperature piston compressor. If medium-temperature model is used for deep freezing working condition, internal valve plate and piston ring will wear rapidly. xiteliduo Source factory of refrigeration can supply low-temperature piston refrigeration compressor in bulk, and provide customized service according to quick-freezing project parameters. When purchasing low-temperature piston compressors, purchasers need to confirm evaporation temperature and refrigerant type. Regular maintenance should pay attention to exhaust temperature and oil viscosity. If exhaust temperature exceeds the allowable range, stop the machine to check condenser fouling and expansion valve setting.
