制(zhi)(zhi)冷(leng)(leng)(leng)机(ji)可分(fen)为(wei):紧缩式(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)(leng)(leng)机(ji)、接(jie)收(shou)式(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)(leng)(leng)机(ji)、蒸(zheng)(zheng)汽(qi)放射式(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)(leng)(leng)机(ji),半导体(ti)系体(ti)例(li)冷(leng)(leng)(leng)。此中蒸(zheng)(zheng)汽(qi)紧缩式(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)(leng)(leng)机(ji)(活(huo)塞式(shi)(shi)(shi)(shi)、反转展转式(shi)(shi)(shi)(shi)、螺(luo)杆式(shi)(shi)(shi)(shi)、离(li)心(xin)式(shi)(shi)(shi)(shi))、接(jie)收(shou)式(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)(leng)(leng)机(ji)和蒸(zheng)(zheng)汽(qi)放射式(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)(leng)(leng)机(ji)操纵较为(wei)普遍(bian)。今(jin)朝,我国除(chu)多(duo)数大冷(leng)(leng)(leng)量和特(te)别用处的(de)冷(leng)(leng)(leng)冻机(ji)外(wai),普通用处的(de)活(huo)塞式(shi)(shi)(shi)(shi)、离(li)心(xin)式(shi)(shi)(shi)(shi)、螺(luo)杆式(shi)(shi)(shi)(shi)、涡旋式(shi)(shi)(shi)(shi) 、溴化锂接(jie)收(shou)式(shi)(shi)(shi)(shi)、蒸(zheng)(zheng)汽(qi)放射式(shi)(shi)(shi)(shi)制(zhi)(zhi)冷(leng)(leng)(leng)机(ji),和冷(leng)(leng)(leng)冻、冷(leng)(leng)(leng)藏、高温实验(yan)等装备都能本身(shen)制(zhi)(zhi)作。

各种(zhong)类型制冷(leng)机首要特色以下:

1.紧缩制冷

1)螺杆式(shi)制冷机(ji):布局简略(lve)、易损件少、操(cao)纵寿命长、单级紧缩比高,在大中型(xing)制冷量规模内有代替活塞(sai)式(shi)的(de)趋向。

2)活(huo)塞式制(zhi)冷机(ji):手艺成(cheng)长比拟成(cheng)熟,效力高(gao),操纵温度(du)规模广(guang),可制(zhi)成(cheng)大中小型各类规格产物(wu),是各类制(zhi)冷机(ji)中操纵较广(guang)的(de)机(ji)种。

3)离(li)心(xin)式制(zhi)冷(leng)(leng)机(ji)(ji):操纵(zong)高速扭转(zhuan)的叶(ye)轮使制(zhi)冷(leng)(leng)剂气体(ti)取得动能,而后经由过程扩压(ya)(ya)器进步其(qi)压(ya)(ya)力并冷(leng)(leng)却液化,节省而制(zhi)冷(leng)(leng)。具备布局松(song)散,单机(ji)(ji)制(zhi)冷(leng)(leng)量大,可(ke)停止(zhi)能量调(diao)理等特色。用于空(kong)调(diao)的机(ji)(ji)械多接纳R11、R12制(zhi)冷(leng)(leng)剂。

2.接(jie)收制冷(leng)

操纵接收剂对制(zhi)冷(leng)(leng)剂的吸附感化使制(zhi)冷(leng)(leng)剂蒸发而制(zhi)冷(leng)(leng)。经常(chang)使用的有氨——水(shui)接收式制(zhi)冷(leng)(leng)机(ji)和溴(xiu)化锂——水(shui)接收式制(zhi)冷(leng)(leng)机(ji),用热源作为(wei)能(neng)源,耗损(sun)电(dian)力少,运行安稳,易损(sun)件少,能(neng)量调(diao)理规模大(da),是一种新成长起来的制(zhi)冷(leng)(leng)机(ji)种类。
