Embodiment Construction

[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] In the present invention, unless stated otherwise, the used orientation words such as "up and down" are usually for the direction shown in the drawings or for the vertical, vertical or gravity direction The terms used to describe the relationship between the parts; "inside and outside" usually refer to the inside and outside of the chamber relative to the chamber or the radial inside and outside relative to the center of the circle, and "top and bottom" are relative to the conventional installation. In terms of the outdoor heat exchanger 4 under the circumstances.

[0038] Such as image 3 As shown, the present invention provides a heat pump system. The...

Abstract

The invention discloses a heat pump system. The heat pump system comprises a compressor (1), a hot water heat exchanger (2), a throttling device (3), an outdoor heat exchanger (4), a water tank (7) and a circulating water pump (8), wherein the compressor (1), the hot water heat exchanger (2), the throttling device (3) and the outdoor heat exchanger (4) are arranged in sequence in a refrigerant circulation loop, and the water tank (7) and the circulating water pump (8) are arranged in sequence in a water loop. The system further comprises a heat exchanger (10), a refrigerant bypass pipe (11) and a hot water bypass pipe (12). The heat exchanger absorbs operation waste heat of the compressor and heats circulating media in the refrigerant bypass pipe and the water bypass pipe. The inlet end of the refrigerant bypass pipe is connected to the outlet end of the throttling device in a switched mode through a refrigerant reversing valve (5). The outlet end of the refrigerant bypass pipe is connected with the inlet end of the outdoor heat exchanger. The inlet end of the hot water bypass pipe is connected to the outlet end of the circulating water pump in a switched mode through a hot water reversing valve (6). The outlet end of the hot water bypass pipe is connected with the inlet end of the hot water heat exchanger. The heat pump system can use the operation waste heat of the compressor to defrost and preheat water, so that the operation waste heat of the compressor is used more fully.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a heat pump system of a heat pump water heater. Background technique [0002] Heat pump water heaters will experience frost during winter use. For the defrosting method of the heat pump, no matter it is a direct heating water heater or a circulating water heater, it generally adopts a four-way reversing valve to change direction, or adopts a hot gas bypass method, that is, when entering the defrosting process, through the " The "hot gas bypass" mode directs the high-temperature and high-pressure refrigerant discharged from the compressor directly into the evaporator for defrosting. These methods will have a certain impact on the generation of hot water during the defrosting process or the problem of poor defrosting effect, and at the same time, the user's comfort experience of using hot water will have a certain impact. [0003] In addition, a heat pump sys...
