c The Refrigation Cycle
Inside a refrigerator, a compressed gas in liquid form is released through an expan-
sion valve into the low pressure of an evaporator. Here the liquefied gas evaporates
(boils). The expansion valve controls how much refrigerant boils, and thus, how
much heat ft absorbs. The refrigerant, now in gas form, circulates through the cool-
ing coils carrying the heat away with
