Abstract

Refinements introduced in an air conditioning system that includes a reverse cycle refrigeration unit operable to proportionally relatively hot or relatively cold air according to the direction of flow of the refrigerant through the unit, said unit including an expansion device (10) characterized in that said system comprises a body member (22) having opposite faces and a refrigerant expansion duct (24) that extends through said body member (22) between said faces, having a first of said faces a flat surface (28) around the end of said duct (24) to limit the passage of refrigerant towards said first face and into said duct (24) in a first quantity, when said unit is operating to provide relatively hot, and the other of said faces having a concave configuration (26) around the end of said duct (24) to limit the passage of refrigerant to said other face and into said conduit in a second quantity less than said first quantity, when said unit is operating to provide relatively cold air.
