Abstract
The present disclosure provides a method for controlling a fresh air machine. The method for controlling the fresh air machine of an air-conditioner includes: determining whether a fault occurs in a return air temperature sensor of the fresh air machine when the fresh air machine operates normally; closing an internal valve corresponding to the fresh air machine and keeping a fan motor operating, when the fault occurs in the return air temperature sensor; determining whether a fault occurs in an delivery air temperature sensor of the fresh air machine; when the fault does not occur in the delivery air temperature sensor of the fresh air machine, obtaining an delivery air temperature of the fresh air machine and controlling the fresh air machine to operate again by using the obtained delivery air temperature as a new return air temperature. The present disclosure also provides a fresh air machine. The method for controlling the fresh air machine of the present disclosure may solve the problem that the fresh air machine cannot operate again when the fault occurs in the return air temperature sensor of the fresh air machine, thereby improving the usage experience of the user for the air-conditioner.
