Embodiment 1

[0039] One of the specific implementations of a heat recovery type air-cooled heat pump unit of the present invention, such as figure 1 As shown, a first refrigerant circulation system 100 and a second refrigerant circulation system 200 are included. The first refrigerant circulation system 100 and the second refrigerant circulation system 200 share the same heat exchanger 15 and heat preservation water tank 28 on the air-conditioning side. Wherein, the first refrigerant circulation system 100 adopts the total heat recovery heat exchanger 30, and the second refrigerant circulation system 200 adopts the partial heat recovery heat exchanger 27, and the present invention coordinates and controls the two refrigerant circulation systems, While making more effective use of condensation heat, the production of domestic hot water can reach a higher temperature and the temperature of the thermal insulation water tank 28 can be accurately controlled, so as to realize the purpose of reus...

Embodiment 2

[0062] The second specific embodiment of a heat recovery type air-cooled heat pump unit of the present invention, as figure 2 As shown, the main technical solution of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment adopt the explanation in Embodiment 1, and will not be repeated here, and are described in figure 2 neutralize figure 1 The same parts bear the same reference numerals. The difference between this embodiment and Embodiment 1 is that part of the heat recovery heat exchanger 27 in the second refrigerant circulation system 200 is placed outside the heat preservation water tank 28 .

[0063] Specifically, the second refrigerant cycle system 200 includes a second compressor 24, a third four-way valve 23, a fourth four-way valve 20, a second air-side finned heat exchanger 21, and a second throttling device 19 , the sixth one-way valve 22, the seventh one-way valve 16, the eighth one-way valve 17, the ninth one-way...

Embodiment 3

[0065] The third embodiment of a heat recovery type air-cooled heat pump unit of the present invention is as follows: image 3 As shown, the main technical solution of this embodiment is the same as that of Embodiment 1, and the features not explained in this embodiment adopt the explanation in Embodiment 1, and will not be repeated here, and are described in image 3 neutralize figure 1 The same parts bear the same reference numerals. The difference between this embodiment and Embodiment 1 is that the first refrigerant cycle system 100 is provided with a solenoid valve 7 and a first throttling device 9, and the solenoid valve 7 and the first throttling device 9 are connected in series and connected with the fifth one-way The valves 8 are connected in parallel. Adding the solenoid valve 7 and the throttling device 9 can realize the defrosting operation in the air-conditioning and heating mode, and the domestic hot water mode defrosting operation mode can be selected by the u...

Abstract

The invention discloses a heat recovery type air cooling heat pump unit comprising a first refrigerant circulating system and a second refrigerant circulating system, wherein the first refrigerant circulating system comprises a first compressor, a first four-way valve, a second four-way valve, a first air side fin type heat exchanger, an air conditioner side heat exchanger, a first air-liquid separator, a total heat recovery heat exchanger, a hot water circulating water pump, a heat preservation water tank and a valve; the second refrigerant circulating system comprises a second compressor, a third four-way valve, a fourth four-way valve, a second air side fin type heat exchanger, an air conditioner side heat exchanger, a third reservoir, a second air-liquid separator, a partial heat recovery heat exchanger, a heat preservation water tank and a valve. According the invention, heat is ensured to be effectively recovered and reused, and environment is protected from thermal pollution, thereby being environmental friendly and saving energy. In addition, the defects that air conditioner heating and daily hot water supply can not be carried out simultaneously, and the traditional total heat recovery air conditioner system which only has a single heat recovery system can not produce higher-temperature daily hot water at low temperature in winter can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heat recovery type air-cooled heat pump unit. Background technique [0002] As an alternative means to solve heating problems, heat pumps have great advantages from both technical and economical points of view. Heat pump technology is a way to convert low-grade heat, such as air, water (including: surface water, groundwater, etc.), solar energy, soil, waste heat, etc., into high-grade heat, such as heating heat. Its working principle is: when the heat pump is running, the evaporator absorbs heat from the heat source (heat collection), and provides heat to the heat-using object. [0003] At present, with the development of social economy, more and more air-cooled heat pump units are adopted by people. In summer, when the air-cooled heat pump unit is running, it will emit a large amount of condensation heat to the environment through the air-side fin heat exchanger. Th...
