摘要： The refrigerant charge adequacy of an air conditioning system is determined by the sensing of two temperatures in the system, one being at a midpoint in a condenser coil and the other being the temperature in the liquid line of the condenser discharge, with the difference then being indicative of the degree of subcooling, which, in turn, may be indicative of refrigerant charge condition. The method is refined by measuring a third temperature at the compressor discharge, with the three temperature values then being used to calculate a pair of residual values which provide an indication of whether the two temperature approach is useful in determining charge adequacy under the existing conditions and if not, whether the system is overcharged or undercharged.

摘要： A method for determining the adequacy of the refrigerant charge in an air conditioning system based upon both the instantaneous degree of subcooling present in the liquid refrigerant in the refrigerant line at a location whereat only liquid refrigerant is present and a calculated average subcooling value based upon accumulated instantaneous subcooling values. The adequacy of the refrigerant charge in the system may be indicated by an alert indicating “check charge” or by a series of lights including a first indicator light indicating that the refrigerant charge is low, a second indicator light indicating that the refrigerant charge is high, and a third indicator light indicating that the refrigerant charge is correct.

摘要： The invention is directed to an accumulator device which has an outer housing having an inlet and an outlet, and a U tube contained within the housing. The device also includes a filter which is positioned inside the housing adjacent the inlet. Dryer means in the form of a desiccant are also contained inside the housing. The device is positioned upstream of a compressor and functions to filter unwanted debris which would otherwise enter the compressor and cause potential damage.

摘要： A control system for a crank case heater for an inverter operated compressor of a cooling system includes a contactor operably connected to the crank case heater and an inverter controller compressor and at least one compressor temperature sensor disposed at the compressor to sense a compressor temperature and an compressor internal temperature sensor. A controller is operably connected to the crank case heater and the at least one compressor temperature sensor and configured to close the contactor to energize the crank case heater independently from operation of the compressor when the at least one compressor temperature sensor senses a compressor temperature below a desired threshold.

摘要： A heat pump is provided having a first heat exchanger and a second heat exchanger. A compressor is fluidly coupled to the first heat exchanger and the second heat exchanger. A reversing valve is fluidly coupled between the first heat exchanger and the second heat exchanger. The reversing valve is adapted to flow of a refrigerant from the compressor to the first heat exchanger during heating mode and to the second heat exchanger during a cooling mode. A thermal expansion valve is positioned between the first heat exchanger and the second heat exchanger. An electronic expansion valve is positioned between the first heat exchanger and the second heat exchanger. A controller is electrically coupled to operate the electronic expansion valve between a fully open, a fully closed and a modulated position depending on the operation of the compressor.
