a.At the evaporator outlet
b.At the condenser outlet (liquid line)
c.At the compressor suction
d.At the filter on the return duct
Giải thích
Subcooling is measured at the condenser outlet by comparing the liquid line temperature to the saturation temperature for the high-side pressure. It indicates how much the liquid has cooled below its condensing point. Subcooling is a primary charging check on TXV systems.
