A heat pump system using a non-azeotropic refrigerant mixture comprising a main refrigeration circuit, an engine coolant circuit, and a refrigerant rectifier circuit interfacing with main refrigeration circuit, and the engine coolant circuit. The refrigerant rectifier circuit comprises in order of decreasing relative elevation a condenser, a storage vessel in communication with a condenser, a rectifier in communication with a storage tank and a condenser, a receiver vessel in communication with a rectifier, and a boiler in communication with the rectifier and the receiver vessel. The refrigerant rectifier circuit is used to adjust the relative concentrations of lower boiling point refrigerant, and higher boiling point refrigerant in the non-azeotropic refrigerant mixture thereby changing the cooling or heating capacity of the heat pump system.

Refrigerant composition control system for use in heat pumps using

A heat exchange system for a heat pump in which the cooled fluid and the cooling fluid are maintained in a counterflow heat exchange relationship in a heat exchanger in both the heating and cooling modes of operation of the heat pump. The heat exchange system comprises a refrigeration coil, a liquid distributor, a vapor distributor, an outlet manifold, expansion means, vapor refrigerant/inlet distributor valve means, vapor refrigerant/outlet manifold valve means, liquid refrigerant/inlet distributor valve means and liquid refrigerant/outlet manifold valve means.
