Abstract

A control module for a heating, ventilating, and air conditioning system includes a housing having an air flow conduit formed therein. An evaporator core is disposed in the air flow conduit, wherein at least a portion of the evaporator is configured to receive a first fluid from a first fluid source therein. An internal thermal energy exchanger is disposed in the air flow conduit downstream of at least a portion of the evaporator core and upstream of a blend door disposed in the air flow conduit. The internal thermal energy exchanger is configured to receive a second fluid from a second fluid source therein, wherein the first fluid is a refrigerant and the second fluid is at least one of a phase change material, a coolant, and a phase change material coolant.

Claims
