Fully enclosed piston refrigeration compressor integrates compression assembly and motor inside a sealed shell. It features compact structure, low noise and convenient installation, widely adopted in small and medium cold storage and commercial refrigeration projects. xiteliduo Source factory of refrigeration develops and manufactures fully enclosed piston refrigeration compressor, providing reliable refrigeration host and technical support for cold storage renovation and new construction projects.
Product application characteristics: Fully enclosed piston refrigeration compressor is sealed in welded shell. It has good leak-proof performance and low noise level during operation. The whole machine is pre-assembled and tested before delivery. It needs less on-site assembly work. Main specifications cover 2HP~8HP, suitable for medium-temperature preservation cold storage, supporting R22 and R404A refrigerants. Built-in thermal overload protection and pressure protection device. The unit will cut off power automatically when overheating or overpressure occurs, protecting motor and compression components. Compared with semi-hermetic models, fully enclosed structure is more compact, occupying smaller installation space. The internal lubrication system is pre-set, with stable oil supply under normal working conditions. Its limitation is that on-site disassembly repair cannot be realized. Once internal core parts are damaged, whole unit replacement is usually needed. The shell surface can be treated with anti-rust coating for different ambient conditions. Standard connection ports are reserved for convenient matching with small cold storage refrigeration systems.
Application fields & working scenarios: Fully enclosed piston refrigeration compressor is suitable for small fruit and vegetable preservation cold storage, small supermarket freezer, small food workshop cold storage and other medium-temperature low-load scenarios. For cold storage with area less than 300㎡ and low daily door opening frequency, fully enclosed piston compressor is a cost-effective option. Many small food merchants and local engineering contractors search fully enclosed piston refrigeration compressor for small cold storage projects. When renovating old small cold storage in Zhejiang, clients contact Zhejiang cold storage refrigeration compressor manufacturers to replace outdated compressors. This model is widely selected for projects with limited equipment room space and low maintenance demand. Engineers will confirm refrigerant type and cooling capacity parameters when selecting fully enclosed piston refrigeration compressor.
Engineering application case: A local food retail enterprise in Shaoxing, Zhejiang renovated a 180㎡ fruit preservation cold storage. The original old refrigeration unit had aging performance and frequent shutdown. The target warehouse temperature is 3~7℃. The enterprise contacted xiteliduo Source factory of refrigeration for renovation scheme. After heat load calculation and site inspection, 3HP fully enclosed piston refrigeration compressor was selected, matched with air-cooled condenser. The original pipeline was cleaned, and aging sealing parts and filter drier were replaced. Vacuum pumping and pressure holding leak detection were finished after pipeline reconnection. Refrigerant was filled and expansion valve was calibrated. After renovation, the cold storage stably maintains target temperature. Noise of compressor in equipment room is lower than 62dB, which meets the on-site environmental requirement. The enterprise’s staff only need simple daily inspection of running current and temperature. The renovated cold storage has run steadily for 2 years. The power consumption per unit volume is reduced by about 12% compared with old unit. In the scheme comparison, the project team found that semi-hermetic model can be repaired on site, but the initial purchase cost is higher. This small preservation cold storage has low load and simple working condition, fully enclosed piston refrigeration compressor can meet demand with better cost performance.
Fully enclosed piston refrigeration compressor is widely used in small cold storage projects, but it is not suitable for low-temperature deep freezing working conditions with high compression ratio. xiteliduo Source factory of refrigeration provides fully enclosed piston refrigeration compressor and supporting accessories, and supplies for cold storage engineering companies. For fully enclosed units, daily maintenance focuses on keeping condenser clean and checking running current. If liquid hammer occurs, the whole compressor may be damaged quickly. System design must guarantee good oil return and avoid liquid refrigerant entering compressor cylinder. When clients inquire about cold storage refrigeration compressor price, fully enclosed and semi-hermetic models have obvious price difference. Users should select models according to actual working condition and later maintenance capacity, not only by price.
