壓(ya)(ya)縮(suo)(suo)機按其(qi)原理可分為容(rong)積(ji)型(xing)(xing)壓(ya)(ya)縮(suo)(suo)機與速(su)度型(xing)(xing)壓(ya)(ya)縮(suo)(suo)機。容(rong)積(ji)型(xing)(xing)又(you)(you)分為:往(wang)復式壓(ya)(ya)縮(suo)(suo)機、回轉式壓(ya)(ya)縮(suo)(suo)機;速(su)度型(xing)(xing)壓(ya)(ya)縮(suo)(suo)機又(you)(you)分為:軸流(liu)式壓(ya)(ya)縮(suo)(suo)機、離心式壓(ya)(ya)縮(suo)(suo)機和(he)混流(liu)式壓(ya)(ya)縮(suo)(suo)機。
如今(jin)家用(yong)冰(bing)箱和空(kong)調(diao)器壓縮(suo)機(ji)(ji)都是(shi)容積式(shi)(shi)(shi)(shi),其(qi)中又可分為往復(fu)式(shi)(shi)(shi)(shi)和旋轉式(shi)(shi)(shi)(shi)。往復(fu)式(shi)(shi)(shi)(shi)壓縮(suo)機(ji)(ji)使用(yong)的是(shi)活塞、曲(qu)(qu)柄(bing)、連桿機(ji)(ji)構或活塞、曲(qu)(qu)柄(bing)、滑管機(ji)(ji)構,旋轉式(shi)(shi)(shi)(shi)使用(yong)的多是(shi)滾(gun)動轉子(zi)壓縮(suo)機(ji)(ji)。在(zai)商用(yong)空(kong)調(diao)上(shang),又多是(shi)離心式(shi)(shi)(shi)(shi)、渦旋式(shi)(shi)(shi)(shi)、螺桿式(shi)(shi)(shi)(shi)。
按應用(yong)范圍(wei)又(you)可(ke)分(fen)為低背(bei)壓式(shi)(shi)、中(zhong)背(bei)壓式(shi)(shi)、高背(bei)壓式(shi)(shi)。低背(bei)壓式(shi)(shi) ( 蒸發溫(wen)(wen)度(du) -35 ~ -15 ℃ ) ,一(yi)般用(yong)于(yu)家(jia)用(yong)電冰箱、食品(pin)冷(leng)凍箱等(deng)(deng)。中(zhong)背(bei)壓式(shi)(shi) ( 蒸發溫(wen)(wen)度(du) -20 ~ 0 ℃ ) ,一(yi)般用(yong)于(yu)冷(leng)飲柜、牛(niu)奶冷(leng)藏(zang)箱等(deng)(deng)。高背(bei)壓式(shi)(shi) ( 蒸發溫(wen)(wen)度(du) -5 ~ 15 ℃ ) ,一(yi)般用(yong)于(yu)房間空(kong)氣調(diao)節器、除濕機、熱泵等(deng)(deng)。
