在了解空調壓縮機的工作原理之前，先來認識下空調壓縮機的工作回路。空調壓縮機的工作回路分為蒸發區和冷凝區，空調壓縮機在空調制冷劑回路中起壓縮驅動制冷劑的作用。空調制冷時，中央空調壓縮機把制冷劑從低壓區抽取來經緊縮后送到高壓區冷卻凝結，高品質電動防火閥經過散熱片分發出熱量到空氣中，制冷劑也從氣態變成液態，壓力升高。制冷劑再從高壓區流向低壓區，經過毛細管放射到蒸發器中，壓力驟降，液態制冷劑立刻變成氣態，經過散熱片吸收空氣中大量的熱量。這樣循環應用就完成了制冷系統。壓縮機通過節流裝置節流之后，通入到蒸發器中，電動防火閥廠家將所需要冷卻的媒介冷卻換(huan)熱(re)(re)。例如將蒸(zheng)發器(qi)連接到樓里的各個房(fang)(fang)間，蒸(zheng)發器(qi)內的蛇行管將同空氣(qi)進行換(huan)熱(re)(re)，再(zai)(zai)通過鼓風將冷氣(qi)吹向房(fang)(fang)間的空氣(qi)當中。而蒸(zheng)發器(qi)蛇行管內的冷凍劑(ji)換(huan)熱(re)(re)后變成低壓蒸(zheng)氣(qi)回(hui)到壓縮(suo)機，再(zai)(zai)被壓縮(suo)機壓縮(suo)，這樣循環利用就完成了制冷系統。
