Abstract
The present invention is provided with: an evaporator () in which a compressed refrigerant is vaporized; an expansion valve expanding the refrigerant before the refrigerant flows into the evaporator (); refrigerant pipes () that connect the evaporator () and the expansion valve to each other; and a unit case () housing the evaporator (), the expansion valve, and the refrigerant pipes (), and including an air flow channel () for passing air through the evaporator (). A refrigerant pipe housing chamber () is disposed in the unit case (), and housing the refrigerant pipes (). The refrigerant pipe housing chamber () is partitioned while being isolated from the housing section for the evaporator () and the air flow channel (). The outer circumferential surfaces of the refrigerant pipes () are separated from the inner wall surface of the refrigerant pipe housing chamber (). Furthermore, the thickness (t) of the wall of the refrigerant pipe housing chamber () is greater than the thickness (t) of the wall of the unit case ().
