compressor is the core host of complete cold storage refrigeration system, undertaking core functions of refrigerant compression and pressure lifting. With advantages of multi-scenario adaptability and simple maintenance, piston models are widely used in all kinds of food storage cold storage. xiteliduo Source factory of refrigeration focuses on production and manufacturing of cold storage refrigeration compressor, providing matched piston refrigeration compressor products and system supporting schemes for high humidity and low-temperature working conditions of seafood cold storage.
Product application characteristics: Cold storage refrigeration compressor can be divided into fully enclosed piston models and semi-hermetic piston models. Different structures adapt to different cold storage scales. The working principle of piston structure depends on reciprocating movement of pistons inside cylinders to compress gaseous refrigerant and complete refrigeration cycle. The equipment is built-in with pressure protection and motor overload protection, which will stop automatically under abnormal working conditions. Product specifications cover 2HP to 20HP, compatible with R22 and R404A refrigerants. Low-temperature enhanced models can meet continuous cooling demand of quick-freezing cold storage. The unit can run alone or multiple units can work in parallel to start and stop compressors automatically according to cold storage heat load and optimize energy consumption. Pressure holding leak detection is finished before delivery to check refrigerant leakage risks. Vibration index is controlled within specification range to reduce pipeline fatigue damage risks in long-term operation. For coastal seafood cold storage, anti-salt fog anti-corrosion coating can be provided for housing to resist salt fog corrosion in air and slow rust of shell and electrical terminals. Standardized interfaces are reserved for equipment to assemble complete refrigeration system with condenser, evaporator and expansion valve.
Application fields & working scenarios: Application scenarios of cold storage refrigeration compressor cover preservation cold storage, freezer cold storage, seafood cold storage, quick-freezing cold storage and low-temperature storage in food processing workshop. Seafood cold storage stores fish, shrimp and shellfish. The warehouse keeps low temperature and high humidity all year round, and air in equipment room contains salt fog, which puts forward higher requirements on anti-corrosion ability of compressors. Fruit and vegetable preservation cold storage focuses on medium-temperature stable working conditions, while meat freezer cold storage needs stable low-temperature output at -18℃. Small cold storage projects commonly adopt 2HP~8HP piston compressor for cold storage. Large warehousing cold storage selects multiple 10HP,15HP,20HP piston units running in parallel. Aquatic enterprises concentrate in Zhejiang industrial belt. A large number of enterprises build or renovate seafood cold storage. Clients will directly visit cold storage refrigeration compressor manufacturers in Zhejiang to inspect workshop, production process and test process. When selecting models, engineering contractors will refer to parameter keywords to confirm low-temperature working parameters of semi-hermetic piston refrigeration compressor and matched refrigerant models.
Engineering application case: An aquatic enterprise in Shaoxing, Zhejiang built a 650 ㎡ seafood cold storage for long-term storage of frozen aquatic products. The designed warehouse temperature is -20℃, and the equipment room is close to seaside with high salt fog content in air. The project team and technical staff of xiteliduo Source factory of refrigeration surveyed site conditions. Considering salt fog in environment, high temperature in summer and warehouse insulation conditions, 10HP semi-hermetic piston refrigeration compressor with two-units parallel and R404A refrigerant was selected. Anti-salt fog coating was added on compressor shell. On pipeline design, reasonable pipeline gradient was set to guarantee smooth oil return. All pipeline welds were treated with anti-corrosion. In system commissioning stage, vacuum pumping was completed step by step, refrigerant was filled in batches, expansion valve was calibrated, and suction superheat was stably controlled at 6K~10K. After cold storage operation, warehouse temperature is stably maintained at -20℃ all year round. When the highest temperature of equipment room reaches 39℃ in summer, the unit runs normally under high load. Operation and maintenance team carries out anti-corrosion inspection every quarter and verifies safety valve every year, replacing refrigeration oil and filter elements according to running hours. After 3 years of equipment operation, no shell corrosion or refrigerant leakage occurs, guaranteeing storage quality of seafood products. At the early stage of project, the client inquired about common faults of piston compressor for cold storage. The manufacturer provided fault troubleshooting manual in advance and trained on-site operation staff to identify typical faults such as liquid hammer, oil shortage and excessive exhaust pressure.
Many clients ask how much is cold storage refrigeration compressor per set during inquiry. Quotation is affected by horsepower, structure type, anti-corrosion treatment and matched electric control. xiteliduo Source factory of refrigeration provides customized piston refrigeration compressor for cold storage. Configuration can be adjusted according to project working conditions. OEM orders are also accepted for bulk supply to domestic engineering contractors and overseas foreign trade clients. The working principle of piston refrigeration compressor is the key content for engineers. Operation staff who understand compression cycle principle can identify abnormal working conditions earlier. In old cold storage renovation projects, when replacing aging cold storage refrigeration compressor, condenser and pipeline aging should be evaluated at the same time. Sealing parts of pipelines should be replaced if necessary to avoid leakage after new unit startup. Crankcase heating belt needs to be activated in winter low-temperature operation to prevent refrigerant migration into crankcase diluting refrigeration oil and avoid liquid hammer at startup.
