ABSTRACT:
This invention relates to a hot water system which utilizes heat from the refrigerant of a refrigeration system to produce hot water. A condenser as part of the hot water system is especially designed with greater heat exchange surface than would normally be provided with the refrigeration system so that water at convection flow and at a higher temperature than normal can be used in the condensing unit and yet achieve the necessary absorption of heat from the refrigerant passing through the condenser as required for proper operation of the refrigeration system.
In one embodiment of the condenser unit a de-superheating coil is located at the top of the housing to overlie the top of an inverted can arrangement within the housing. Between the sides of the housing and the inverted can is located a sheet type heat exchange surface which is preferably pillowed. Water passages are defined between the sides of the housing and the inverted can arrangement by the layers of heat exchange sheet, and further passages are defined between the windings of the coil at the top. The refrigerant flows downwardly through the coil at the top where it is de-superheated, and then through the side heat exchange sheet where it is condensed, while water entering the bottom of the housing is heated as it moves upwardly by convection flow out of the top of the condenser.
