Condensation system for set-top air conditioner

The invention discloses a condensation system for a set-top air conditioner. The condensation system comprises a casing, a condenser module and a condensation fan. The condenser module and the condensation fan are arranged in the casing, the side of the casing is provided with an air suction port, the top of the casing is provided with a blowing port, and the condensation fan is arranged below the blowing port. The condensation fan is an axial flow fan, a rotating shaft of the condensation fan is in the vertical direction; and after outside air sucked in from the air suction port passes through the condenser module, under the effect of the condensation fan, the air is blown out through the blowing port from bottom to top. The condensation system has the advantages that air outside the air conditioner is sucked into the air conditioner through a wind grating of the casing, performs heat exchange with the condenser module and then is discharged out of a wind grating port at the top of the casing through the condensation fan; the condensation system is more rational in structural layout, the air suction port is arranged on the side of the casing, the blowing port is arranged at the top of the casing, and leaves and sundries can be effectively prevented from being adsorbed to the air suction port.
