Problems solved by technology

The title of the invention applied by Xi'an University of Architecture and Technology is "Solution Dehumidification Evaporative Cooling Air Conditioning Refrigeration Device", the application date is January 9, 2007, and the application number is 200710017209.9. It operates throughout the year to cool, dehumidify, heat and humidify the air. It has a compact structure and is easy to miniaturize. During summer operation, the refrigerant can be used to cool the air, solution and the refrigerant itself. The cooling water consumption is small and can be recycled Use the cooling capacity of the indoor exhaust air, but the heat of the indoor exhaust air cannot be recycled during winter operation, so the performance of the device is not high during winter operation

Embodiment 1

[0022] As shown in Figure 1, according to the different working processes in winter and summer, its working process can be divided into summer circulation system and winter circulation system.

[0023] 1. Summer circulatory system

[0024] The summer circulation system consists of five subsystems, which are air handling subsystem, solution dehumidification and regeneration subsystem, refrigeration subsystem, solution cooling subsystem and refrigerant cooling subsystem.

[0025] (1) Air handling subsystem

[0026] It is made up of dehumidifier 17, evaporator 3. The dehumidifier 17 and the evaporator 3 are connected through the air duct 53 to form an air passage in which the air is dehumidified and cooled.

[0027] During work, the processed air first enters the dehumidifier 17 to be dehumidified. After reaching the required humidity, it enters the evaporator 3 to be cooled. After reaching the required temperature, it is sent into the air-conditioned room.

[0028] (2) Soluti...

Embodiment 2

[0083] Embodiment 2 is shown in Figure 2. The only difference between it and Embodiment 1 is: there are two evaporative heat exchangers 27, and there is a group of heat exchangers in each evaporative heat exchanger, and the cooling heat exchanger 43 and the condensation heat exchanger 44 are respectively located therein.

[0084] The composition of other devices is exactly the same. The working process of the circulation system in winter and summer, the connection mode of equipment is also identical with embodiment 1.

[0085] In Embodiment 1 and Embodiment 2, the throttling mechanism 4 between the cooling heat exchanger 43 of the evaporative heat exchanger 27 and the working medium pump 26 also has the following two arrangements:

[0086] ①The throttling mechanism 4 can be arranged on the pipeline 42 that the direct contact heat exchanger 24 is connected to the condensing heat exchanger 44 of the evaporative heat exchanger 27. At this time, between the pipeline (28) and the ...

Embodiment 3

[0090] It differs from Embodiment 1 and Embodiment 2 in that only one throttling mechanism 4 is set in the system, which is usually set on the pipeline 62 where the evaporator 3 is connected to the passage (82, 83) of the four-way valve 80, and it can also be set On the pipeline 31; between the pipeline (28) and the pipelines (29, 30) there may be no flow control valve (36). During the cycle in winter, a bypass pipe 45 and a flow direction control valve 36 may also be provided between the suction end and the discharge end of the working medium pump 26 to reduce the flow resistance of the refrigerant in the pipeline.

[0091] The composition and connection methods of other equipment are the same as those in Embodiment 1 and Embodiment 2. During the circulation process of winter and summer, the throttling mechanism 4 works normally to throttle the refrigerant.

[0092] In this embodiment, when working in winter, the evaporative heat exchanger 27 can only recover the heat of the...
