Embodiment Construction

[0013]Embodiments of a high efficiency hybrid space and water heating heat pump system includes a hot water module and a water heater operably coupled to a heat pump for providing auxiliary hot water heating to the water heater by switching the heat pump from either the space heating mode or the space cooling mode to a hot water heating mode. During the hot water heating mode, the heat pump is operated in the heating mode for specifically heating hot water. The hot water module includes a controller for executing algorithms for controlling one or more valves that diverts vapor refrigerant from a compressor located in the heat pump in an outside environment to a hot water refrigerant circuit in order to heat cold water diverted from a hot water heater. Additionally, the controller would execute algorithms to determine whether to switch from either the space-heating mode or the space-cooling mode to a hot water heating mode during a call for hot water. Additional algorithms may also d...

Abstract

A hybrid space and water heating heat pump system includes a heat pump including an outdoor assembly and an indoor assembly; a hot water module including a first heat exchanger, a controller, and a water pump connected to a water line, the first heat exchanger being configured for heating water; and a water heater in fluid communication with the hot water module, the water heater configured for receiving heated water from the first heat exchanger; wherein the controller is configured to select between one of conditioning an interior space or heating of the water in the first heat exchanger; and wherein the heat pump is configured for circulating a refrigerant through a first refrigerant circuit in response to the conditioning of the interior space and circulating the refrigerant through a second refrigerant circuit in response to the heating of the water in the first heat exchanger.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. provisional patent application Ser. No. 61 / 554,651 filed Nov. 2, 2011, the entire contents of which of incorporating herein by reference.FIELD OF THE INVENTION[0002]This invention relates generally to a hybrid heat pump system and, more particularly, to a hot water module coupled to an existing heat pump system and water heater for supplementing the heating needs of the water heater when the heat pump system is not providing space heating or cooling.DESCRIPTION OF RELATED ART[0003]Reversible heat pumps are commonly used for cooling and heating a climate controlled comfort zone such as a residence or a building. A conventional heat pump includes a compressor, a suction accumulator, a reversing valve, an outdoor heat exchanger with an associated outdoor fan, an indoor heat exchanger with an associated indoor fan, an expansion device operatively associated with the outdoor heat exchanger and a seco...
