Problems solved by technology

But this mechanism has the following defects: (1) there are many moving parts in the valve mechanism, especially considering that these moving parts need to start and stop frequently, resulting in poor reliability of the valve mechanism; (2) the valve mechanism additionally increases The flow resistance in the air channel increases the fan load and reduces the energy efficiency of the air conditioning system; (3) The valve mechanism is prone to vibration and noise, which affects the user experience

Embodiment 2

[0029] Embodiment two structure such as Figure 5 ~ Figure 8 As shown, it includes the first heat exchange unit 1 (the first heat exchanger 1-1, the second heat exchanger 1-2, the first four-way valve 1-3, the first expansion valve 1-4, the first compressor 1-5), the second heat exchange unit 2 (the fourth heat exchanger 2-1, the third heat exchanger 2-2, the second four-way valve 2-3, the second compressor 2-4, the second condensing device 2-5), the first air duct 6 and the third air duct 8, the second air duct 7, and two guide rails 9 (the first guide rail and the second guide rail).

[0030] The two first heat exchangers 1-1 and the second heat exchanger 1-2 of the first heat exchange unit 1 and the second heat exchange unit 2 or the fourth heat exchanger 2-1 and the third heat exchanger 2- 2 are exactly the same.

[0031] A four-way valve (the first four-way valve 1-3, the second four-way valve 2-3) is arranged between the heat exchanger and the compressor of the first h...

Abstract

The invention provides a heat pump system of an air conditioner. The heat pump system of the air conditioner comprises a first air channel, a second air channel, a third air channel, a first heat exchange unit and a second heat exchange unit. The first heat exchange unit is arranged inside the first air channel, the second air channel and the third air channel. The second heat exchange unit is arranged inside the first air channel, the second air channel and the third air channel. The first heat exchange unit comprises a first heat exchanger and a second heat exchanger which are connected witha first steam compression system. The second heat exchange unit comprises a third heat exchanger and a fourth heat exchanger which are connected with a second steam compression system. Compared withthe prior art, the heat pump system of the air conditioner has the beneficial effects that it is just needed to control the movement manner of the steam compression systems according to an actual airconditioning demand, and the requirement for continuous work of the air conditioner can be met without the needed for additionally arranging any valve mechanism in the air channels

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to an air conditioning heat pump system in which an evaporator and a condenser need to be changed periodically. Background technique [0002] In order to improve the energy efficiency of the air-conditioning system, a Chinese patent (application number 201610316615.4) discloses an air-conditioning system using a heat exchanger coated with a desiccant. The typical features of this type of air conditioner are: (1) In the same vapor compression cycle, the evaporator and condenser are exactly the same; (2) The same heat exchanger cannot work continuously and must be used periodically as an evaporator or condenser, In other words, the two heat exchangers need to periodically switch between the evaporator and the condenser. This brings about a difficult problem: considering that the air inlet and outlet of the air conditioner are fixed, the air path of the air conditioner also needs to be...
