Nettet8. apr. 2024 · Subcooling is a measurement of temperature DECREASE of a liquid below its saturation (mixed liquid/vapor) temperature at a given pressure. For example, water boils at 212° Fahrenheit at sea level (atmospheric pressure of 14.7 PSIA). If water is 212°F and at atmospheric pressure at sea level, you can be sure it is at saturation, which … Nettet12. mar. 2024 · Also, note how much warmer the liquid line is than the outdoor temperature. It should be between 4° and 18° warmer than the outdoor temperature. If it is above or below that range, connect gauges. Measure the suction line temperature outside. If it is at or above 65°, the compressor is in danger of overheating / oil breakdown.
