WebWe use gauges and a temperature probe to measure subcooling, just like when measuring superheat. 2. We check the temperature of the liquid line near the condenser coil. 3. We’ll check the head pressure at the condenser, comparing the readings to the manufacturer’s standard. 4. Then we subtract the two numbers to calculate subcooling. WebJul 28, 2024 · High Superheat and Low Subcooling. High superheat and low subcooling are probably the most common combination you will encounter. They reveal a system low on refrigerant charge. The first clue of an undercharge often comes from low refrigerant pressures. But remember, pressure only shows one aspect of system operation.

Superheat for most systems should be approximately 10F measured at the evaporator; 20°F to 25°F near the compressor. If the suction pressure is 45 psi, (which converts to 22°F) and the suction temp is 32°F, the system still has 10°F of superheat. The fact that these readings are ...
WebMi a túlhűtés képlete? Számítsa ki az aláhűtést a következőképpen: túlhűtés = CT – T. Hűtőközeg-keverék esetén használja a telített folyadék (buborék) hőmérsékletét kondenzációs hőmérsékletként. A kondenzátorban általában nem következik be túlhűtés, hacsak nem folyik vissza folyadék a kondenzátorba. WebJan 28, 2024 · To measure subcooling and superheat, you will need a thermometer and a pressure gauge. A thermocouple or thermistor can also be used to measure the refrigerant temperature. Additionally, you may need a set of manifold gauges, which are used to measure the pressure of the refrigerant in the system. Steps to Follow for Diagnosis
WebJun 12, 2005 · Subcooling is desirable for several reasons: It increases the efficiency of the system since the amount of heat being removed per pound of refrigerant circulated is greater. In other words, you pump less refrigerant through the system to maintain the refrigerated temperature you want. This reduces the amount of time that the compressor …
