[0002] Air conditioning, also known as air conditioners, refers to equipment that manually adjusts and controls the temperature, humidity, flow rate, and other parameters of the ambient air within a building or structure. Air conditioning generally consists of several major components: cooling / heating source equipment, a cold and hot medium distribution system, a terminal unit, and other auxiliary equipment such as a refrigeration unit, water pumps, fans, and piping systems.

The cooling water enters the interior of the box body 1, passes through the first filter 415 and the second filter 418 in turn, and the impurities and scale in the cooling water are filtered out. The first frame 413 and the second frame 416 can be conveniently extracted from their respective corresponding extraction ports 419 for cleaning and maintenance in the later stage; then, the cooling water flows to the cooling plate 423 for cooling. During this period, the heat inside the box body 1 is conducted out through the heat conducting head 427, and dissipated into the cooling box 424 through the heat exchange pipe 426, and then discharged from the air outlet 428 through the first fan 429 and the second fan 4201, ensuring that the cooling water can be recycled, and finally discharged from the box body 1 through the water outlet 53. The one-way valve 55 and the sealing sleeve 56 provided on the water outlet 53 are to ensure that the cooling water discharge will not cause backflow and leakage.
