How to choose the compressor for cold storage

The cold storage compressor is an important cold storage equipment. When choosing a cold storage compressor, many factors need to be considered.

First of all, the compressor should be selected according to the actual purpose of the cold storage. If it is used to store low-temperature food, you can choose a low-noise, high-efficiency oil-free condensing compressor; if it is used for pharmaceutical preservation or other special industrial storage, you can use an efficient water-cooled compressor; if it is used for large-capacity storage, you can use multiple low-power parallel compressors.

Secondly, the outdoor climate of the cold storage should also be taken into consideration. In cold or hazy weather, a semi-enclosed compressor with fan power transmission and no suction flow device can be considered; under normal climatic conditions, closed or semi-enclosed compressors without fan power transmission can be used.

In addition, the working mode of the cold storage, energy efficiency standards, working flow, sound efficiency standards, construction difficulty, sanitary water supply, maintenance convenience and customer requirements for product performance and cost performance should also be considered. Only after forming a reasonable matching plan based on the above factors and conditions can you correctly select a set of cold storage compressors that are reasonably matched to your own use occasions and can get ideal benefits.

The working principle of the piston compressor is to release the pressurized gas from the container and then release it through a sealing ring to form a sealed circulation flow channel. When the gas in the flow channel is accelerated, a certain vacuum effect will be generated. Subsequently, the pressurized gas in the flow channel will be cooled by evaporative cooling.

In addition, the device also includes electric heating elements, packing valves, filtering devices, shock absorbers, regulating valves, zero oxygen sensors, temperature switches, safety protection devices and various electronic components. These are essential components to ensure normal performance and provide effective convenience.

Especially when used in large-capacity cold storage, we often connect multiple piston compressors to each other to bear a large workload and provide effective cooling capacity. Furthermore, the device is suitable for energy-saving operation and has a significantly efficient cooling effect.
