螺桿式制冷系統(tǒng)的原理
Principle of screw refrigeration system
螺桿式冷水機組是蒸氣壓縮式制冷機組中的一種。其工作原理是通過壓縮機對氣態(tài)制冷劑施加能量，從而使其壓力、溫度得型線 流水槽模具 景觀石 檢查井鋼模具 保定通風管道 重慶窗簾 隔離墩模具 保定保潔公司 到提高，然后再通過冷凝、節(jié)流等等過程，使之變成低壓，低溫液態(tài)制冷劑在蒸發(fā)器內(nèi)蒸發(fā)為氣體，與此同時，它從周圍環(huán)境（比如冷水）中獲得熱量使載冷劑的溫度降低，從而達到人工制冷的目的。
Screw chiller is a kind of vapor compression chiller. Its working
principle is to apply energy to the gaseous refrigerant through the
compressor, so as to increase its pressure and temperature, and then
turn it into low pressure through condensation, throttling and other
processes. The low-temperature liquid refrigerant evaporates into gas in
the evaporator. At the same time, it obtains heat from the surrounding
environment (such as cold water) to reduce the temperature of the
refrigerant, so as to achieve the purpose of artificial refrigeration
