The humidification is independently controlled, when humidification is needed, the humidification air duct is started, and refrigeration or defrosting can be simultaneously operated. So design makes refrigeration, the humidification setting in the case realize more easily. When the auxiliary evaporator needs defrosting, the system needs to judge the frosting condition of the main evaporator first and control the main evaporator according to the priority principle of the main evaporator, and the method specifically comprises the following steps:
