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 image 3 , 4 , 7, 8, including 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, First compressor 1-5), second heat exchange unit 2 (fourth heat exchanger 2-1, third heat exchanger 2-2, second four-way valve 2-3, second expansion valve 2-4 , the second compressor 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 heat exchange unit 1 and the second h...

Abstract

The present invention provides an air-conditioning heat pump system, comprising: a first air duct, a second air duct, and a third air duct; The second air passage and the third air passage; the second heat exchange unit, the second heat exchange unit is arranged in the first air passage, the second air passage and the third air passage; The first heat exchange unit includes a first heat exchanger and a second heat exchanger connected through a first vapor compression system; the second heat exchange unit includes a third heat exchanger and a second heat exchanger connected through a second vapor compression system Four heat exchangers. Compared with the prior art, the beneficial effects of the present invention are as follows: it only needs to control the moving mode of the vapor compression system according to the actual air-conditioning requirements, without adding any valve mechanism in the air duct, and can meet the requirement of continuous operation of the air-conditioning.

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...
