Abstract
A heat exchanger comprising a refrigerant tube in coil form leading from the output side of a compressor and a water tube in coil form tapped from a source of water to be heated, the tubes being coiled together so that each coil of the water tube is interposed between a coil of said refrigerant tube, and vice-versa. Inner and outer cylindrical sleeves are disposed within and around the coiled tubes thereby defining an annulus which enhances the heat transfer from said refrigerant tube to the water tube. A housing surrounds said coiled tubes and said sleeves, and sealed end caps are provided at each end of the exchanger.
Claims11
A heat exchanger comprising:
- (a) a refrigerant tube in coil form leading from the output side of a compressor of an air-conditioning system or heat pump;
- (b) a water tube in coil form, said water tube being connected to a source of water to be heated, said water and refrigerant tubes being coiled together so that each coil of said water tube is interposed between a coil of said refrigerant tube, and vice-versa;
- (c) an inner cylindrical sleeve around which the inner surfaces of said coiled tubes are wrapped;
- (d) an outer cylindrical sleeve positioned closely around the outer surfaces of said coiled tubes, said inner and outer cylindrical sleeves defining an annulus therebetween thereby enhancing the heat transfer from said refrigerant tube to said water tube, and
- (e) housing means surrounding said coiled tubes and said sleeves.
