WebJan 5, 2024 · 4327 kPa. Refrigerant subcooling affects the mass flow rate through the inlet refrigerant density and the location of the flash point in the tube, which is related to the available subcooled liquid pressure drop (the pressure difference between upstream pressure and saturated liquid pressure corresponding to the inlet temperature). As … WebSubtract the lower temperature measured on the liquid line from the saturated temperature and you have subcooling! 105°F Sat Temp - 93°F Actual Line Temp = 12°F of Subcooling Ok, now practically speaking, how do we measure subcooling? Below is an example of an R-410A split system air conditioner.
