冷冻机是用压缩机改变冷媒介质的压力变化来达到低温制冷的机械设备(这里指氟利昂作为冷媒介质),分为风冷和水冷两种。冷冻工作原理是压缩机通过改变氟利昂冷媒的物理性质,并由外部风冷或水冷通过交换带走热量来制冷的。部分公司内若是有多台冷冻机,那么对多台冷冻机进行集中控制显得尤为重要,可以产生较大的经济价值。 Freezer is the compressor to change the pressure change of refrigerant medium to achieve low-temperature refrigeration machinery and equipment (here as Freon refrigerant medium), divided into two kinds of air-cooled and water-cooled. Refrigeration works by compressors by changing the physical properties of freon refrigerant, and by the external air-cooled or water-cooled exchange exchange to take away heat to refrigeration. If there are multiple freezers in some companies, centralized control of multiple freezers is especially important, which can have great economic value.
