When humidification is required, the atomizing sheet is activated to atomize water, and the water is driven by the air flow of the blower 34 to be emitted from the mist outlet holes 38 along the main pipe 33 and the branch pipe 36. Then the heat exchange chamber 61 is reached through the first branch pipe 162 and the second branch pipe 163, and then the heat exchange chamber 61 is reached into the main pipe 33 and the water storage tank 31 respectively, and the circulation is repeated.

When there is a certain temperature difference and the temperature difference is small, the cooling fins 41 are activated to adjust the temperature of the water, thereby affecting the temperature of the upper chamber 12.

When the temperature difference is large, the refrigeration assembly is started to regulate the temperature of the gas passing through the heat exchange chamber 61.

When the temperature of the condenser 65 and the compressor 64 is too high, the second electromagnetic valve 72 is opened, the third electromagnetic valve 165 is closed, and the cold air from the upper chamber 12 enters the heat dissipation period through the first branch pipe 162, the air return box 67 and the communication pipe 71 to cool the condenser 65 and the compressor 64.

If the new trend humidity is lower, start the atomizing piece, improve the humidity of new trend in the same way. If the temperature difference of the fresh air is small, the refrigerating sheet 41 is started; if the temperature difference is large, the refrigeration assembly is started. When the refrigeration assembly is started, the fresh air can be divided into two paths to enter the main pipeline 33, one path enters the water storage tank 31 to directly enter the main pipeline 33, and the other path enters the water storage tank 31 and then enters the main pipeline 33 through the heat exchange chamber 61 and the centrifugal fan 63.
