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 condenses 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 additional refrigerant vapor; second compression means including an inlet port and two, first and second outlet ports and operable to: receive the refrigerant vapor from the evaporator means through the inlet port; increase the pressure thereof; and pass at least a portion of the refrigerant vapor to at least one of the condensing means and the first compression means through the first and second outlet ports respectively; and a conduit operable to pass at least one of the refrigerant vapor leaving the evaporator means and the refrigerant va…
