Abstract

A heat pump appliance may include a cabinet, a sealed thermodynamic assembly, a blower fan, a temperature sensor, and a controller. The sealed thermodynamic assembly may include a fluid compressor, an evaporator, and a condenser disposed along the air path. The temperature sensor may be mounted to the evaporator to detect temperature at the evaporator. The controller may be configured to direct a drying operation. The drying operation may include activating the fluid compressor to motivate a refrigerant through the sealed thermodynamic assembly, activating the blower fan to motivate the airflow across the condenser, directing the fluid compressor to an inactive state following activating the blower fan, detecting an evaporator temperature at the temperature sensor while the fluid compressor is in the inactive state following activating the blower fan, and adjusting activation of the blower fan based on the detected evaporator temperature.
