Abstract: A heating and cooling system integrated with a domestic water heating system wherein the heating and cooling system utilize recaptured heat and direct that heat back into the system for domestic water heating. Various paths for exchanging heat from refrigerant to water are utilized to provide space heating or space cooling with simultaneous water heating, and water heating alone when there are no space cooling or space heating demands.
Abstract: A system is provided for heating and storing a liquid within a tank. Disposed within the tank is a heating unit which effects stratification of the tank into upper and lower liquid storage sections whereby the liquid in the upper storage section is at a first predetermined temperature which is higher than the temperature of the liquid within the lower storage section. A first control element is operatively connected to the heating unit and controls the operation thereof so as to maintain the liquid in the upper storage section at the first predetermined temperature. The upper and lower storage sections are interconnected by a passage assembly. The passage assembly includes a pump for effecting controlled circulation of the liquid from the upper storage section to the lower storage section.
Abstract: An improved heating and cooling system for an associated home or office environment is provided which facilitates efficiency and enhances overall system operation. The operative elements of the heating and cooling system including a compressor, desuperheater, pump, water heater tank, blower, heat exchange unit and central electrical control unit are all contained in a single, common cabinet providing thermal and noise insulation and drain pan-spillage containment. Ambient and stand-by thermal loss is minimized by reason of the cabinet and the proximity of the operative elements therein. Facilitation of the desuperheating function is further provided through defining three distinct water temperature layers within the water heater tank and maintaining predetermined water temperatures within those layers through selective operation of the desuperheater and a bypass arrangement.
