摘要： In a heat pump system designed for use with a relatively low pressure refrigerant, provision is made, by use of a vapor pressure control system, to use a higher pressure refrigerant without replacement of the indoor coil and the line set. The vapor pressure is sensed during periods of heat pump operation, and when the pressure reaches a predetermined maximum threshold level, the outdoor fan speed is reduced to thereby cause the vapor pressure to be reduced. When the vapor pressure is reduced to a predetermined minimum threshold level, then the fan speed is resumed so as thereby allow the vapor pressure to again be increased.

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.
