A dehumidifier apparatus comprises a housing having an air inlet for receiving incoming air, an air outlet spaced therefrom for allowing the air to exit from the housing, the housing being configured to provide an interior air passageway connecting the air inlet to the air outlet; an air mover mounted within the air passageway for moving the air through the air passageway from the air inlet to the air outlet; a compressor mounted in the housing for compressing a refrigerant; an evaporator located within the air passageway for evaporating the refrigerant during a dehumidifying cycle, and thereby cooling air flowing through the evaporator and causing water in the air to condense on a surface of the evaporator; a condenser for condensing the refrigerant during the dehumidifier cycle, the condenser being located in the air passageway downstream of the evaporator in series with the evaporator; refrigerant flow lines configured to allow for a flow of the refrigerant between the compressor, the condenser, and the evaporator; and a defrosting cycle system for performing a defrosting cycle during a frosting condition of the evaporator, wherein during the defrosting cycle the flow of the refrigerant is reversed, causing the evaporator to condense the refrigerant and the condenser to evaporate the refrigerant. The compressor and the air mover are configured to run continuously during the dehumidifying cycle and the defrosting cycle.
