This circuit is an energy-saving retrofit scheme for the central air-conditioning air supply system. Its working principle is: air enters the air-conditioning system inlet from the return air inlet and the fresh air outlet, and the air-conditioning system is installed at the entrance to control the amount of air intake. The filtered air continues to the air. The mixing chamber is sent to the humidifier after being blown by the blower, and the humidified air is sent to cool or warm (depending on the season), enters the air distribution chamber through the water retaining plate, then goes to the air supply pipe, and finally enters the air conditioning room. The air supply is generally completed by several blowers at the same time. The required air supply power is determined as needed and should be adjustable. Accepting part of the return air can save heat, and the fresh air outlet can add fresh air.
