Aug 2, 2012 ... Fully understanding superheat and subcooling is the key to a refrigeration system performing at its optimum level.

When checking a superheat or subcool temperature the procedure is the same as for a single-component refrigerant. Superheat is checked by measuring the temperature of the vapor line, measuring the pressure, then subtracting the saturated temperature from the measured temperature.For this example the Liquid line Temp is 95 degrees. Subtract the Liquid line Temperature from the Liquid Saturation Temperature and you get a Subcooling of 15. “Typically” on TXV systems the Superheat will range between 8 to 28 degrees with a target of about 10 to 15 degrees. The Subcool range on TXV systems will range from about 8 to 20.

Common reasons for superheating and subcooling include issues such as liquid line restriction, malfunctioning metering systems, and limited airflow, all of which can lead to high superheating and low subcooling levels. 1. stines broussard la Mar 22, 2023 · It's simply shedding heat energy, moving left all the way through the saturation dome, and even subcooling the refrigerant slightly at the end. Point 3 : The "throttle" is the metering device that separates the high-pressure condenser from the low-pressure evaporator -- usually a thin capillary tube in household refrigerators. The liquid line temperature is 88 ° F. Subtracting the two numbers gives 36 ° F. High superheat and high subcooling indicates a problem with the metering device. Keep in mind that subcooling won't increase on systems with a liquid line receiver, as extra liquid will fill the receiver instead of backing up in the condenser.
