Condenser for a Portable Dehumidifier
A portable dehumidifier includes a plurality of microchannel condenser coils and a fan. The fan is located adjacent to an airflow outlet and is configured to generate an airflow that flows into the portable dehumidifier through an airflow inlet and out of the portable dehumidifier through the airflow outlet. The airflow flows through an evaporator and the plurality of microchannel condenser coils in order to provide dehumidification to the airflow. The plurality of microchannel condenser coils includes first and second microchannel condenser coils. The first microchannel condenser coil is located so as to receive the airflow after it has passed through the evaporator. The second microchannel condenser coil is located proximate to the first microchannel condenser coil on a side of the microchannel condenser coil so as to receive the airflow after it has passed through the first microchannel condenser coil.
