Patent ID: 10473355

Abstract:
A split-system dehumidifier includes an evaporator unit, a heat exchange unit, and a supply fan located inside a structure, and a remote condenser system located outside the structure. The evaporator unit receives a pre-cooled airflow and a flow of refrigerant, and generates a cooled airflow by facilitating heat transfer from the pre-cooled airflow to the flow of refrigerant. The heat exchange unit receives the cooled airflow generated by the evaporator unit and an incoming airflow from within the structure, and generates the pre-cooled airflow by facilitating heat transfer from the incoming airflow to the cooled airflow. The heat transfer transforms the received cooled airflow into an outgoing airflow having a relative humidity less than a relative humidity of the cooled airflow. The supply fan provides the outgoing airflow to inside the structure. The remote condenser system uses ambient air from outside the structure to cool the flow of refrigerant.
