• 118
• 127
• 139
• MR 9.4.3

In the ___, the liquid refrigerant is now under much reduced pressure. It will evaporate or boil very rapidly. This, in turn, cools the ___. The compressor creates a low pressure drawing the vapor from the ___. Then it compresses the vapor back into the high side. What is this component called?

• condenser
• refrigerant receiver
• cylinder of refrigerant
• evaporator
