Hybrid heat pump system

Abstract

A system and a method for a hybrid heat pump system including first compression means operable to form a refrigerant in vapor form and increases the pressure of the refrigerant vapor; condensing means arranged to receive the pressurized vapor and condense the vapor under pressure to a liquid; pressure reduction means through which the liquid refrigerant leaving the condensing means passes to reduce the pressure of the liquid to form a mixture of liquid and vapor refrigerant; evaporator means arranged to receive the mixture of liquid and vapor refrigerant that passes through the pressure reduction means to evaporate the remaining liquid to form refrigerant vapor; second compression means including two, first and second inlet ports and an outlet port and operable to: receive at least a portion of the refrigerant vapor from the evaporator means and the pressurized vapor from the first compression means through the first and second inlet ports respectively; increase the pressure thereof; and pass the pressurized vapor to the condensing means through the outlet port; and a conduit operable to pass a portion of the refrigerant vapor leaving the first compression means to the second compression means.
