Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 As shown, the heat pump hot water system proposed by the present invention includes a heat pump unit consisting of a compressor 1 , a reversing valve 2 , an indoor heat exchanger 3 , a first throttle valve 4 and an outdoor heat exchanger 6 connected through pipelines. A first solenoid valve 5 is provided between the first throttle valve 4 and the outdoor heat exchanger 6, and a branch is drawn between the first throttle valve 4 and the first solenoid valve 5, and a second section is arranged in turn on the branch. The flow valve 7 and the water side heat exchanger 8 are then communicated with the reversing valve 2. The water inlet pipe of the water side heat exchanger 8 communicates with the bottom of the water tank 11 through the water pump 9 and the one-way valve 10, and a three-way valve 12 is arranged on the water outlet p...

Abstract

The invention discloses a heat pump hot water system and a hot water system control method. The heat pump hot water system comprises a heat pump unit, a second electromagnetic valve (5) is arranged between a first throttling valve (4) of a heat pump unit and an outdoor heat exchanger (6), a branch is led out of the position between the first throttling valve (4) and the second electromagnetic valve (5), the branch is provided with a second throttling valve (7) and a water side heat exchanger (8) and communicates with a reversing valve (2), and a water inlet and outlet pipe of the water side heat exchanger (8) communicates with a water tank (11). T he heat pump hot water system comprises a refrigeration heat recycling heating water running mode, a direct heat heating water running mode andan independent refrigeration running mode. The heat pump hot water system with the refrigeration heat recycling function achieves the aim of saving energy, and can meet multiple use needs through optimization control.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a direct heating heat pump capable of realizing refrigeration heat recovery [0002] A hot water system and a control method for the hot water system. Background technique [0003] At present, air conditioners and heat pump water heaters are all necessary electrical products for families. In the prior art, these two electrical appliances are basically purchased separately. When the air conditioner is running alone, the high-temperature heat from the outdoor side is directly discharged into the air, resulting in energy waste. On the other hand, the water heater needs to consume electricity or gas, which is also a considerable expense. If the air-conditioning system cools down the space, the external heat dissipation needs to be used for the water heater to heat up the water in the container, and the two are just complementary. Therefore, how to organically combine the a...
