4 What is the refrigerator? Ø y letting-down the pressure of chilled and highly compressed refrigerant, we can obtain a cold temperature of refrigerant. y adjusting the pressure letting-down level, we can obtain a wanted temperature level of refrigerant. Ø y cooling after compressing a vapor stream, we can obtain a liquefied refrigerant. 04/33
