A hybrid heat pump system comprising a heat pump loop integrated with a hydronic loop. The hybrid heat pump system offers multiple modes of operation to provide increased versatility and improved performance. Each of the loops can operate independently. In addition, the loops can operate in conjunction with each other in both heating and cooling modes. Still further, the hydronic loop can provide a reheat function when the heat pump loop is operating in the cooling mode to provide improved dehumidification of the air delivered to the conditioned space. The heat pump loop may include a hot gas bypass functionality for capacity control and/or freeze protection. The hydronic heat exchanger and the space heat exchanger of the heat pump loop may be combined in a compact single slab construction with a slit fin preventing cross-conduction between the heat exchanger sections.
An embodiment of the instant disclosure comprises a reversible heat pump and water heating system for conditioning a space and heating water. The system comprises a refrigerant circuit that includes a compressor, a source heat exchanger, a space heat exchanger, and an expansion device. A 4-way reversing valve alternates between heating and cooling modes of operation. The system includes a heat exchanger for heating water in the water heating loop, and a 3-way valve that either actuates the refrigerant flow through the water heater heat exchanger or bypasses at least a portion of the refrigerant flow around the water heater heat exchanger. The heat pump system is operable in at least five modes—space heating only, space cooling only, water heating only, and either space heating or space cooling combined with water heating. Use of a modulating 3-way valve allows the amount of the refrigerant flow through the water heating heat exchanger to be adjusted to precisely match space conditioning and water heating demands and stable operation of the heat pump system. Either of the space and source heat exchangers may be bypassed and deactivated to reduce the heat pump system power consumption.

An integrated heat pump and water heating circuit for space heating and cooling and heating domestic water. The circuit includes a first heat exchanger (20) for the domestic water, a second heat exchanger (22) for the source (heat source/sink) with a first dedicated expansion valve (24), and a third exchanger (30) for the space with a second dedicated expansion valve (34). The circuit has four modes of operation. In the first mode, the space is cooled and heat is rejected to the source. In the second mode, the space is heated while heat is absorbed from the source. In the third mode, the circuit absorbs heat from the source and heats the water supply. In a fourth mode, the water supply is heated and the space is cooled simultaneously. In each mode, one heat exchanger is inactive, and the charge from the inactive heat exchanger is reclaimed to the suction side of the compressor.
A water-cooled air conditioning system using a regenerative condenser water circuit to reheat the supply air during a dehumidification mode. The air conditioning system may be any type of water-cooled system, including a water source heat pump or water-cooled air conditioner. The reheat circuit circulates water leaving the condenser through the reheat heat exchanger and then returns the water to the condenser inlet. Thus, the reheat circuit ensures that water leaving the condenser is warm enough to provide sufficient reheating for the supply air, regardless of the water source temperature. In addition, a modulation assembly controls the amount of water flowing through the reheat circuit, and thereby its temperature, so that the temperature of the reheated supply air can be maintained within a narrow range.
