Embodiment Construction

[0020] In order to facilitate the understanding of those skilled in the art, the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings:

[0021] as attached figure 1 As shown, it is a preferred implementation of the present invention, which includes an outdoor heat exchanger 1, a filter, a throttling device 2, an indoor heat exchanger 3, a heat exchanger 4 for hot water, a compressor 5, and a gas-liquid separation Device 6, central controller 7, No. 1 four-way reversing valve 8, No. 2 four-way reversing valve 9, No. 1 check valve 11 and No. 2 check valve 10, all components are connected by pipelines. Wherein, the outdoor heat exchanger 1 is placed outdoors for absorbing and releasing heat to the outside air. The indoor heat exchanger 3 is placed indoors for cooling and heating the indoor air. The heat exchanger 5 for hot water is used to heat the cold water to a set temperature, and is generally placed in the heat p...

Abstract

The invention discloses an air source three-purpose heat pump water heater which comprises an outdoor heat exchanger, a filter, a throttle device, an indoor heat exchanger, a heat exchanger for heating water, a compressor, a gas liquid separator and a center controller, a No. 1 four-way reversing valve, a No. 2 four-way reversing valve and two check valves which are communicated through pipelines. The whole equipment can run under five condition modes by controlling the two four-way reversing valves and the two check valves. Compared with the prior art, the invention has the advantages: firstly, under all the running modes, when the equipment runs, all the three heat exchangers can participate, thereby the problem of uncontrollable accumulation of refrigerant or lubricating oil in the prior air source three-use heat pump water heater, a system pipeline is simple, the amount of control valve is small, the complexity of the system is lowered, the equipment cost is lowered, and the fault points are reduced; and secondly, the whole equipment is in a controllable state under various running modes when running to ensure that the system runs stably.

Description

technical field [0001] The invention relates to an air source three-purpose heat pump water heater. Background technique [0002] Air source three-purpose heat pump water heater refers to a heat pump water heater that can be used to produce sanitary hot water, refrigeration and air conditioning, and heating. The heat source for producing sanitary hot water and heating is outdoor air, and generally includes three Heat exchangers, that is, heat exchangers for hot water, indoor heat exchangers and outdoor heat exchangers that absorb and release heat from the external ambient air. Among them, the hot water heat exchanger is a heat exchanger used to heat cold water to a set temperature. Indoor heat exchanger A heat exchanger used for cooling (absorbing heat from the room being conditioned) or heating (releasing heat to the room being conditioned). The outdoor heat exchanger is a heat exchanger used to release heat to the external ambient air (such as cooling) or absorb heat fro...
