ABSTRACT:
An apparatus for managing refrigerant charge in an air conditioning unit comprising a cooling circuit through which a refrigerant flows from a compressor, through a condenser, and through an evaporator, a heat recovery circuit extending from a first terminus between the compressor and the condenser to a second terminus between the evaporator and the condenser, a heat recovery unit located between the first and second terminus of the heat recovery circuit, a first valve located between the condenser and the first terminus, a second valve located between the first terminus and the heat recovery unit, a third valve located on a cooling charge circuit having a first end on the cooling circuit between the condenser and the evaporator and a second end at the evaporator, a fourth valve located on a heating charge circuit having a first end on the heat recovery circuit and a second end at the evaporator, and a logic unit for sensing a saturated temperature and opening and closing the valves based upon the saturated temperature to manage the refrigerant charge.
