  • Retractable handle for air valve heat pump
    Patent number: 4297853
    Abstract: The present invention relates to a heat pump that utilizes unidirection refrigerant wherein air directed across the condenser and evaporator is redirected for different operations. While the heat pump is operating in the cooling mode, manually operable dampers are positioned so that outdoor air is circulated through the condenser and indoor air is circulated through the evaporator. Conversely, in the heating mode, the dampers are manually positioned so that outdoor air is circulated through the evaporator; and indoor air is circulated through the condenser for heating the air.
