Abstract
A hybrid heat pump system including first compression means operable to form a refrigerant vapor and increases the pressure of the refrigerant vapor; condensing means to receive pressurized vapor and condense the vapor to a liquid; pressure reduction means through which the liquid refrigerant passes to reduce the pressure of the liquid to form a mixture of liquid and vapor refrigerant; evaporator means to receive the mixture of liquid and vapor refrigerant to evaporate the remaining liquid; second compression means including first and second inlet ports and an outlet port to receive a portion of the refrigerant vapor from the evaporator means and the pressurized vapor from the first compression means; increase the pressure thereof; and pass the pressurized vapor to the condensing means through the outlet port; and a conduit to pass a portion of the refrigerant vapor leaving the first compression means to the second compression means.
