The positions of cavity 10 and cavity 2 11 can be swapped by rotating water collecting box 9 180 degrees, so that water receiving trough 12 can be placed below turbid air inlet pipe 17 or fresh air outlet pipe 6. When the fresh air temperature is lower than the turbid air temperature, the air with moisture in turbid air channel 2 will produce condensed water after being cooled, and the condensed water will drip downward and be collected by water receiving trough 12. When the fresh air temperature is higher than the turbid air temperature, condensed water will be produced in the fresh air channel 3.

[0023] As an embodiment of the present invention, a water supply pipe 30 is provided on one side wall of the filter box 16. When the output of condensed water is small, water can be added to the filter box 16 through the water supply pipe 30 to meet the filtering demand for gas.

[0024] The working principle and use process of the present invention are as follows: when in use, the fresh air inlet pipe 17 and the turbid air outlet pipe 8 are connected to the outside through a pipe, and the turbid air inlet pipe 15 and the fresh air outlet pipe 14 are connected to the room through a pipe, and the gas in the pipe is made to flow through a fan (not shown in the figure), and the outdoor air can enter the filter box 16 through the fresh air inlet pipe 17 and contact the water at the bottom. By passing the outdoor air into the water, the dust in the gas can be adsorbed, and the primary filtration is realized, and the filtration amount of the filter plate 20 is reduced. The air distribution plate 23 can be used to The gas is dispersed to increase the contact area between the gas and the water, and the adsorption effect is improved. The gas after water adsorption will enter the installation cylinder 19, and will be filtered through the filter plate 20. The filtered gas will enter the fresh air channel 3, and after heat exchange through the heat exchange core 4, it will be discharged to the room through the fresh air outlet pipe 1 6, the water collection box 9, and the fresh air outlet pipe 2 14. The turbid air in the room will enter the turbid air channel 2 through the turbid air inlet pipe 2 15, the water collection box 9, and the turbid air inlet pipe 1 7, and after heat exchange through the heat exchange core 4, it will be discharged to the outside through the turbid air outlet pipe 8; please refer to Figure 1 When the fresh air temperature is lower than the turbid air temperature, the hot air with moisture in the turbid air channel 2 will be cooled to produce condensed water, which can flow downward along the inner wall of the shell 1 and pass through the turbid air inlet pipe 7 to be collected by the water receiving tank 12; please refer to Figure 2 When the fresh air temperature is higher than the turbid air temperature, condensed water will be generated in the fresh air channel 3. By rotating the water collecting box 9 by 180 degrees, the positions of the cavity 10 and the cavity 2 11 can be swapped, so that the water receiving tank 12 is moved to the bottom of the fresh air outlet pipe 1 6 to receive the condensed water in the fresh air channel 3, so that the condensed water can be collected according to different temperature conditions; the collected condensed water will be temporarily stored in the water receiving tank 12, and when the water in the water receiving tank 12 is stored to a certain height, the float valve 2 25 can be pushed. When the float valve 2 25 is opened, the condensed water can be discharged from the water receiving tank 12. After opening, the water in the water tank 12 can flow into the filter box 16 through the drain pipe 24 and the hose 26, thereby replenishing the water in the filter box 16. When the water stored in the filter box 16 gradually increases, it will push the float valve 22. When the float valve 22 is opened, the water in the filter box 16 will be discharged out of the filter box 16 through the drain pipe 21, thereby replacing the water in the filter box 16. The water replenishment pipe 30 can be used to replenish water into the filter box 16 when the condensate production is small to ensure sufficient water volume and water cleanliness.
