ABSTRACT:
This invention relates to a hot water system which utilizes heat from the refrigerant of a refrigeration system to produce hot water. The utilized heat consists of the superheat of the refrigerant vapor, the latent heat of condensation, and part of the sensible heat of the liquid refrigerant. The water passing through a water-cooled condenser, which is part of the refrigeration system, is heated to a selected temperature by removal of both the superheat of refrigerant vapor, the latent heat of condensation, and part of the sensible heat of the liquid refrigerant as it passes through the condenser. The condenser has a water inlet and an outlet between which is connected to a hot water storage tank. As the water in the condenser is heated by absorption of the superheat of the refrigerant vapor, the latent heat of condensation, and part of the sensible heat of the liquid refrigerant passing therethrough, the heated water rises and flows by convection into the storage tank. Eventually the storage tank may fill completely with water of a selected temperature. A temperature responsive flow restriction device, or thermostat, is located between the water outlet of the condenser and the storage tank, which restricts the flow of water below a preselected temperature. The heated water, being lighter than the balance of the water in the tank, will remain stratified at the top of the tank and may be drawn off as needed.
