Cold storage unit piston compressor acts as the core host of complete refrigeration unit for small cold storage, with high integration level and convenient installation and commissioning. It is widely applied in medium and small cold chain storage projects such as fruit and vegetable preservation cold storage. xiteliduo Source factory of refrigeration produces cold storage unit piston compressor, providing standardized host machine and system design guidance service for cold storage installation companies and agricultural product operators.
Product application characteristics: Cold storage unit piston compressor mostly adopts semi-hermetic piston structure, forming complete cold storage unit together with condenser, liquid receiver and oil separator. The equipment features compact volume, suitable for small cold storage projects with limited space in equipment room. Models cover small and medium specifications of 2HP,3HP,5HP,8HP, compatible with R22 and R404A refrigerants. Medium-temperature models are used for preservation cold storage. Built-in overload and high-low pressure protection modules, standardized electric control interfaces, which can directly match cold storage temperature controller for automatic start-stop control. Single machine running test is finished before delivery. Vibration is controlled within 0.12mm to reduce pipeline vibration cracking risk. Consumable parts have high standardization degree. Piston ring, valve plate and sealing parts are easy to stock. Maintenance does not require large professional equipment. Single machine installation process is simple. Base gradient can be controlled within 0.5°, with shock absorption pads to weaken vibration transmission. Stable oil circuit design of unit guarantees continuous lubricating oil backflow to crankcase and reduces liquid hammer risk. Equipment interface and anti-corrosion configuration can be adjusted according to client demands, supporting customized demand of piston refrigeration compressor.
Application fields & working scenarios: Cold storage unit piston compressor is mainly used in small cold storage scenarios including fruit and vegetable preservation cold storage, small agricultural product storage cold storage and small convenience store freezer cold storage. Fruit and vegetable preservation cold storage maintains temperature from 0℃ to 8℃ for storing citrus, mushrooms, vegetables and other agricultural products, requiring stable temperature inside warehouse. Small piston refrigeration compressor for small cold storage generally selects 2HP to 8HP, with warehouse area mostly from 100 to 500 ㎡. Many local engineering contractors and agricultural product owners search piston refrigeration compressor factory in Zhejiang to visit factory nearby, shorten delivery cycle and obtain on-site commissioning service. Engineers check horsepower parameters during model selection to match warehouse insulation, door opening frequency and maximum summer ambient temperature locally for cooling load calculation.
Engineering application case: A fruit and vegetable cooperative in Shengzhou, Zhejiang built a 260 ㎡ fruit and vegetable preservation cold storage for storing alpine vegetables and citrus. Target temperature inside warehouse is 2~6℃. The warehouse has high door opening frequency and obvious heat load fluctuation. Person in charge of the project investigated how to select piston refrigeration compressor for cold storage. After site survey and heat load calculation, the project team chose 5HP semi-hermetic cold storage unit piston compressor from xiteliduo Source factory of refrigeration, with R404A refrigerant. Single unit configuration was adopted, matched with air-cooled condenser. The manufacturer’s technical team gave suggestions on pipeline layout and oil return design, reminding construction team to control pipeline gradient and avoid liquid hammer. After installation, pressure holding test and vacuum pumping were carried out to confirm no leakage in pipeline system. Refrigerant filling and expansion valve calibration were completed step by step. After cold storage operation, warehouse temperature remains stably within 2~6℃. Temperature fluctuation is controlled within ±0.4℃. Even in summer with frequent door opening, the compressor can adjust running state automatically to stabilize warehouse temperature. The cooperative’s maintenance staff follow the operation manual to check oil level and filter condition monthly. Annual inspection of safety accessories is arranged. The equipment has run for 2 harvest seasons continuously without major failure. The client compared full set unit and separate host scheme. Integrated cold storage piston compressor unit reduces on-site assembly workload and shortens construction period, which is more suitable for small cold storage project with limited construction cycle.
When purchasing cold storage unit piston compressor, purchasers need to confirm whether supporting parts and after-sales technical service are included. xiteliduo Source factory of refrigeration supplies cold storage piston refrigeration compressor and matching spare parts, and supports customized adjustment of unit configuration according to preservation warehouse working conditions. For small cold storage renovation, original old compressors can be replaced with new piston compressor for cold storage. Meanwhile, aging condenser and pipeline sealing shall be inspected. Users shall pay attention to daily operation data of compressors. Once exhaust pressure or oil pressure appears abnormal, stop machine for inspection in time to prevent secondary damage of internal components. Proper heat preservation of suction pipeline can reduce refrigerant flash gas and improve operation efficiency of piston refrigeration compressor.
