cold storage projects. It realizes refrigerant pressurization and heat exchange through reciprocating piston compression. It supports multiple refrigerants and multi-temperature cold storage working conditions. The maintenance threshold of the equipment is moderate, and the spare parts supply chain is mature, making it the preferred model for cold chain engineering contractors. xiteliduo Source factory of refrigeration relies on years of R&D and manufacturing experience in cold storage equipment. It provides piston refrigeration compressor matching schemes according to different cold storage loads and ambient conditions, and supplies cold storage projects at home and overseas steadily.
Product application characteristics: The piston refrigeration compressor adopts reciprocating compression structure. Models cover small horsepower to large horsepower specifications, compatible with mainstream cold storage refrigerants including R22 and R404A. Semi-hermetic models integrate motor and compression cavity into one unit with stable sealing performance. The access panel facilitates disassembly and maintenance in later stages. The unit comes with pressure protection and overload protection modules, which can link with cold storage electric control systems. It will shut down automatically under abnormal conditions such as exhaust overpressure and abnormal current to avoid equipment damage. The unit supports single-unit operation and multi-unit parallel schemes. It can adjust the running quantity automatically according to real-time heat load of cold storage to reduce no-load energy consumption. Every finished unit undergoes a 4-hour continuous running test before delivery. Vibration index is controlled within 0.12mm to reduce pipeline fatigue and refrigerant leakage risks caused by long-term operation. The base of different horsepower models reserves installation adjustment positions. The base gradient can be controlled within 0.5°, adapting to on-site installation requirements in equipment rooms. Customization and OEM service are available to match special project requirements.
Application fields & working scenarios: This compressor is widely used in food cold chain industries, including fruit and vegetable preservation cold storage, meat freezer cold storage, seafood cold storage, small quick-freezing cold storage, and also industrial process cooling and low-temperature raw material storage scenarios. The working temperature of fruit and vegetable preservation cold storage is generally 0~8℃. Medium-temperature piston compressors are selected to stabilize temperature and humidity inside the warehouse, slow down the respiration of fruits and vegetables and extend preservation period. Meat freezer cold storage requires temperature below -18℃, which needs low-temperature piston compressors to increase compression ratio and guarantee continuous and stable cooling. Small cold storage projects mostly adopt 2HP to 10HP piston refrigeration compressors. Large cold storage projects can use multiple piston units in parallel to realize staged capacity regulation. Many food processing factories and agricultural product storage enterprises in Zhejiang industrial belt will look for piston refrigeration compressor factory in Zhejiang when building or renovating cold storage, comparing equipment stability and after-sales supporting capacity.
Engineering application case: An agricultural industrial park in Shaoxing, Zhejiang built a 1200 ㎡ fruit and vegetable preservation cold storage. At the early stage of the project, the engineering side consulted how to select piston refrigeration compressor for cold storage. The site faced problems of high temperature and high humidity in the equipment room in summer. The project team cooperated with xiteliduo Source factory of refrigeration to survey working conditions on site. Finally, 8HP semi-hermetic piston refrigeration compressor with two-units parallel scheme was selected, with R404A as refrigerant. Oil balance pipeline design was adopted to ensure balanced oil level of each host of parallel units and avoid oil shortage failure. After the project was put into operation, the cold storage stably maintained storage temperature from 0℃ to 4℃. Temperature fluctuation inside warehouse was controlled within ±0.5℃. The start-stop frequency of compressors was limited within 6 times per hour to prevent motor loss caused by frequent startup. The equipment has run continuously for 3 harvest seasons. Only regular maintenance of filter elements and lubricating oil was carried out. Spare parts delivery cycle is 3 working days, greatly reducing cold storage shutdown risk. Before the project, the client compared the difference between piston refrigeration compressor and screw machine. This cold storage has seasonal fluctuating load. Piston units feature lower initial investment and simple maintenance, matching the budget demand of medium and small cold storage.
When selecting piston refrigeration compressors, we cannot only compare horsepower parameters. Cold storage temperature, ambient temperature and warehouse insulation should be comprehensively calculated for cooling load. Many purchasers will inquire about how much is cold storage refrigeration compressor per set. Quotation depends on horsepower, refrigerant type, semi-hermetic or fully enclosed structure, and whether supporting electric control is included. xiteliduo Source factory of refrigeration provides customized piston refrigeration compressor and OEM manufacturing service. It supplies steadily for cold storage installation companies and general contractors, and provides equipment room layout suggestions and system commissioning guidance to help smooth project delivery. In daily operation and maintenance, regular inspection of oil separator filter, pipeline insulation and vibration status, and timely replacement of aging sealing parts can extend the designed service life of compressors up to 10 years. For coastal high salt-fog areas, anti-salt fog coating can be equipped for equipment housing to slow metal corrosion and maintain long-term heat exchange efficiency.
