Abstract
A controller is configured to operate a heating, ventilation, and air conditioning (HVAC) system and to actuate sealing structures coupled to an evaporator unit, wherein the sealing structures are configured to prevent airflow from interacting with an evaporator coil during a defrost cycle. The controller is configured to determine if the HVAC system is transitioning from a first mode of operation to a second mode of operation, wherein the second mode is a defrost cycle. In response to determining that the HVAC system is transitioning from the first mode of operation to the second mode of operation, the controller is configured to actuate a first actuator to move a first sealing structure to a second position, wherein the second position is configured to seal an air intake side of a housing of the evaporator unit.
