In addition, the air treatment device provided by the embodiment of the utility model can be applied to a scene where an outdoor unit cannot be installed due to the position of an outdoor unit or a scene where products need to be moved frequently, and has obvious advantages.

By arranging the second heat exchange system 2, indirect heat exchange between the heat exchange liquid and the first refrigerant in the first heat exchange flow channel 12 of the first heat exchange system 1 is realized; by arranging the heat exchange system as a two-stage heat exchange system comprising the first heat exchange system 1 and the second heat exchange system 2, boiling of heat exchange liquid is facilitated, and requirements on the pressure ratio, the exhaust temperature, the exhaust pressure and the like of the first compression device 11 of the first heat exchange system 1 are reduced.

In some exemplary embodiments, as shown in fig. 2, the second heat exchange system 2 is a compression type heat exchange system, and further includes a second compression device 21, where the second compression device 21, the third heat exchange flow passage 22, the second expansion device 23, and the fourth heat exchange flow passage 24 are sequentially connected through a second refrigerant line 211 to form a circulation system.

The first heat exchange system 1 and the second heat exchange system 2 of the heat exchange system can be compression type heat exchange systems, so that the heat exchange system of the air treatment device is a two-stage cascade vapor compression type system. In the first heat exchange system 1, the first compression device 11, the first heat exchange flow passage 12, the first expansion device 13 and the second heat exchange flow passage 14 may be sequentially connected through a first refrigerant pipe 15 to form a circulation system in which a first refrigerant may circulate; in the second heat exchange system 2, the second compression device 21, the third heat exchange flow passage 22, the second expansion device 23 and the fourth heat exchange flow passage 24 may be sequentially connected through a second refrigerant pipe 211 to form a circulation system in which the second refrigerant may circulate; and the second refrigerant in the third heat exchange flow passage 22 can exchange heat with the heat exchange liquid in the heat exchange liquid flow passage, and the second refrigerant in the fourth heat exchange flow passage 24 can exchange heat with the first refrigerant in the first heat exchange flow passage 12, so as to realize indirect heat exchange between the heat exchange liquid and the first refrigerant in the first heat exchange flow passage 12.

The two-stage cascade vapor compression system reduces the pressure ratio, the exhaust temperature, the exhaust pressure and the like of the first compression device 11 and the second compression device 21, and is beneficial to boiling of heat exchange liquid.

In some exemplary embodiments, as shown in fig. 3, the second heat exchange system 2 is an absorption heat exchange system, and further includes an absorber 25, a generator 26, a solution pump 27, and a third expansion device 28, where the absorber 25, the solution pump 27, and the generator 26 are sequentially connected through a first pipe 29, and the generator 26, the third expansion device 28, and the absorber 25 are sequentially connected through a second pipe 210; the generator 26, the third heat exchange flow passage 22, the second expansion device 23, the fourth heat exchange flow passage 24 and the absorber 25 are sequentially connected through a second refrigerant pipeline 211 to form a circulation system.

The second heat exchange system 2 may be an absorption heat exchange system in addition to a compression heat exchange system. In the absorption heat exchange system, the absorber 25, the solution pump 27 and the generator 26 are sequentially connected through a first pipeline 29, the generator 26, the third expansion device 28 and the absorber 25 are sequentially connected through a second pipeline 210, and a circulation system can be formed by sequentially connecting the generator 26, the third heat exchange flow passage 22, the second expansion device 23, the fourth heat exchange flow passage 24 and the absorber 25 through a second refrigerant pipeline 211, and the second refrigerant can circulate in the circulation system.

The absorption heat exchange system is equipment which takes heat energy as power and utilizes the absorption characteristic of a solution to realize the pumping of heat from a low-temperature heat source to a high-temperature heat source. In the absorption heat exchange system, a compressor is not required, but two heat exchange devices of an absorber 25 and a generator 26 are used instead. The function of these two devices corresponds to the function of the compression means in the compression heat exchange system, and therefore the assembly of the absorber 25 and the generator 26 in the absorption heat exchange system and its auxiliary devices (e.g. the solution pump 27 and the third expansion device 28) may be referred to as a "thermal compressor".

When the absorption heat exchange system works, the second refrigerant in the fourth heat exchange flow channel 24 can enter the absorber 25, and the second refrigerant can be absorbed by the concentrated solution from the generator 26 in the absorber 25 to become a dilute solution; the dilute solution of the absorber 25 is fed to the generator 26 via the solution pump 27, in which generator 26 the second refrigerant becomes gaseous, while the dilute solution becomes a concentrated solution, which concentrated solution can be fed to the absorber 26 after passing through the third expansion device 28, and the gaseous second refrigerant can be fed to the third heat exchange flow path 22 and heat the heat exchange liquid in the heat exchange liquid flow path.

When the air conditioner is used for refrigerating, the first heat exchanger 31 can be used as a condenser to realize direct heat exchange between the heat exchange liquid and the high-temperature second refrigerant, so that the heat exchange liquid boils under the action of heat released by the high-temperature second refrigerant to generate steam; the first refrigerant in the first heat exchange flow passage 12 of the intermediate heat exchanger 33 can release heat and be absorbed by the second refrigerant in the fourth heat exchange flow passage 24, so that the second refrigerant in the fourth heat exchange flow passage 24 is evaporated; the second heat exchanger 32 may function as an evaporator to effect cold exchange of the low-temperature first refrigerant with indoor air.

The casing 4 of the air treatment device may be of a unitary structure, so that when the air treatment device is an air conditioner, the air conditioner may be a unitary air conditioner, such as: can be a mobile air conditioner, a window machine or a single-air-pipe integral air conditioner. The single air duct does not represent one air duct in number, but means that the casing 4 is only communicated with the outside through the exhaust duct, and is not connected with the suction duct to the casing 4 from the outside.
