The air conditioning unit includes a water tank 100, a water pump 200, a heat exchanger 300, a packing 400, a filtering device 500, and a flow monitoring device 600. After the water in the water tank 100 is pumped by the water pump 200, heat is exchanged with the heat exchanger 300, and then flows back to the water tank 100 through the packing 400.

A filtering device 500 is provided in the water tank 100 for filtering water flowing out of the water tank 100. As shown in fig. 2, an internal structure of the water tank 100 is schematically shown. The water tank 100 is provided with a water outlet pipe, the filter device 500 is arranged in the water tank 100 and is communicated with an inlet of the water outlet pipe, and water in the water tank 100 flows out of the water tank 100 through the water outlet pipe after passing through the filter device 500. The filter device 500 is provided with a filter structure for filtering water entering the filter device 500, and the filter structure is arranged such that the direction of water flow entering the filter device 500 through the filter structure is different from the inlet direction of the water outlet pipe and/or the water flow entering the filter device 500 through the filter structure is staggered from the inlet of the water outlet pipe.

The filter in the prior art is arranged on the waterway flow pipeline, and adopts a Y-shaped filter screen type structure, so that the water flow is smooth for reducing the resistance loss, the size of the Y-shaped filter can be made large, and the Y-shaped filter occupies a large space. In the embodiment provided by the invention, the filtering device 500 is arranged in the water tank 100, so that the space outside the water tank 100 is not occupied, and the structural arrangement is optimized. Moreover, the direction of water flow entering the filter device 500 through the filter structure is different from the inlet direction of the water outlet pipe and/or the water flow entering the filter device 500 through the filter structure is staggered from the inlet of the water outlet pipe, so that the water entering the filter device 500 through the filter structure can be prevented from being directly pumped away by a water pump connected with the water outlet pipe, impurities can be reduced from entering the water tank, and the problems of blockage and poor heat exchange are reduced.

Optionally, the total filtering area of the plurality of filtering holes 507 is larger than the flow area of the water outlet pipe, so that the water flow resistance can be reduced, and the water flow is smoother.

Optionally, the total filtering area of the plurality of filtering holes 507 is 30% and more greater than the flow area of the water outlet pipe.

A gap is provided between the baffle 105 and the tank bottom plate 103 of the water tank 100, and the flow area of the gap is larger than that of the water inlet. Therefore, the flowing resistance of water flow can be reduced, and overflow can be avoided.

The flow monitoring device 600 may also be used as a monitoring component for whether the filtering device 500 is blocked, and when the filtering device 500 is blocked to reduce the water outlet flow of the water pump 200, an operator may be notified in time to replace the filter plate 503 in time or overhaul other parts of the filtering device 500.

As shown in fig. 8, the flow monitoring device 600 may employ a water flow switch that includes a target 601, a micro switch 602, and a signal output 603. When the system is started, the water flow impacts the target 601 of the water flow switch, the target 601 is displaced, the micro switch 602 is triggered, and the micro switch 602 can feed back a signal to the main board through the signal output end 603. When the water is insufficient due to the blockage of the filter plate or other reasons, the water flow is insufficient to push the target 601 to displace, so that the micro switch 602 cannot feed back signals to the main board, and the system can remind or stop for protection.
