Abstract
The utility model relates to a waste heat recovery system of a compressor of a heat pump water heater. The waste heat recovery system comprises a heat pump main engine and a heat exchange water tank, wherein the heat pump main engine part mainly comprises an air-cooled evaporator, the compressor and a throttling element; a condensing coil pipe is arranged in the heat exchange water tank; after absorbing heat in the ambient air in an evaporator tube, refrigerants is compressed by the compressor to be warmed and boosted; then the refrigerants are condensed by the condensing coil pipe after releasing the heat in the water tank; the condensed refrigerants returns to the evaporator again through the throttling element; and a heat pump circulating loop is formed through such repetition. The periphery of the compressor is filled with heat transfer and storage media; a heat absorbing coil pipe is buried in the heat transfer and storage media; the heat produced when the compressor works is absorbed by utilizing the heat transfer and storage media; and waste heat in the heat transfer and storage media is absorbed by utilizing the heat absorbing coil pipe and then directly or indirectly transferred to water in the water tank, thereby achieving recovery and utilization of the waste heat.
