Abstract:
A refrigeration system, comprising:an evaporator fed with liquid refrigerant and discharging a vapor refrigerant; an accumulator for accumulating vapor refrigerant discharged from the evaporator; a compressor receiving vapor refrigerant from the accumulator, for compressing the vapor refrigerant; a condenser receiving compressed vapor refrigerant from the compressor, for condensing it into liquid refrigerant; a receiver receiving the liquid refrigerant from the condenser and supplying it to the evaporator; a mechanical trap interposed between the condenser and receiver; a tee interposed between the trap and the condenser; said tee including a stem and a pair of coaxial arms orthogonal to the stem, the stem oriented generally horizontally and the arms vertically to form an upper arm and a lower arm, the stem connected to the condenser and the tee lower arm connected to the receiver; and a purge valve fluidly connected to the tee upper arm, selectively operable to permit the selective purging of noncondensable gases from the condenser that have accumulated within the tee upper arm.
