在制冷系統中有一個必不可少的設備就是制冷壓縮機，它為制冷系統進行制冷劑氣體的壓縮輸送，是制冷系統的核心和心臟。而壓縮機的能力和特征決定了制冷系統的能力和特征。
In a refrigeration system is a necessary equipment refrigeration compressor for refrigeration system of refrigerant gas compression transmission, is the core of the refrigeration system and heart. And the power of the compressor and characteristics to determine the ability of the refrigeration system and characteristics.
食品冷庫制冷系統是由一系列的設備依統籌設計組裝、安裝而來。
Food cold storage refrigeration system consists of a series of equipment in accordance with the overall design, assembly, installation.
一般可區分為：制冷主機、制冷風機、控制系統、管路與閥件系統。
Can generally be divided into: refrigeration host, cooling fan, control system, piping and valve system.
在冷媒的選擇方面國內主要使用的是氨系列和氟系列的冷媒。
In the choice of refrigerant domestic mainly USES the ammonia series and series of fluorine refrigerant.
與制冷系統配套的還有壓力平衡裝置、溫度感應裝置、溫度記錄裝置、電器設備等。因此，制冷系統存冷鏈物流的投資中占有較大比重。

And form a complete set of refrigeration system and pressure balance device, temperature sensors, temperature recording devices, electrical equipment, etc. Therefore, the refrigeration system of cold chain logistics investment in a large proportion.
