Abstract
The utility model discloses a fan device for an indoor anti-freezing suspended ceiling in the cold region, and relates to an air-conditioner operation system device. According to the fan device, a small fan is connected into a machine box of a fresh air unit, and 1/3 of fresh air does not pass through a heating coil, is directly supplied to the air outlet end side of the fresh air unit and is mixed with fresh air passing through the heating coil to be supplied to the indoor place. An air returning opening is formed in the sucking end side of the fresh air unit, the air return amount is about 1/3 of the air amount of the fresh air unit, returned air and the 2/3 of the fresh air are mixed, the temperature of cold air passing through the heating coil is higher than the temperature of outdoor places where the air is directly obtained, the anti-freezing effect of water tubes of the unit is accordingly achieved, and the fan device makes it possible for the suspended ceiling type fresh air unit to normally operate in winter. The fan device is suitable for buildings with kitchen and laundry room air supplementation systems.
