WebSimply put, subcooling is the lowering in temperature of the liquid refrigerant in the condenser coil. On a split system air conditioner, the condenser coil is in the outdoor unit. While the system is running, refrigerant exits the vapor compressor and travels through the condenser coil to reject heat into the outdoor air. WebOct 17, 2024 · In the photo, the superheat and subcooling values are being worked out by one of our engineers. This is how we determine a refrigerant shortage. Less latent heat is being absorbed into the chiller refrigerant and so a lot of electricity is being used with little effect to the chilling of the water. Refrigerant Leak Repairs chloe mayer newsweekWebStep 1. Start the refrigeration system and run it for at least 10 minutes to establish steady-state temperatures.

WebAug 29, 2001 · This is often referred to as the heat of compression or work of compression. As its name states, one of the main functions of the condenser is to condense the refrigerant sent to it from the compressor. However, the condenser also has other functions. Desuperheating and subcooling are other important functions of the condenser. WebHow to Check Subcooling. Attach the thermometer to the liquid line. This time, near the condenser. Then take the head pressure in Psi and convert it to the temperature on the pressure/temperature chart. Assuming you are dealing with a R22 system, let’s say the head pressure is 260Psi. This will convert to 120F.

WebDec 26, 2024 · Take a sensible temperature and pressure reading on the liquid line. Find the pressure on your P-T card, gauge, or app and locate the corresponding saturated temperature. The difference is the subcooling amount, and it will always be a lower measured line temperature than saturation when the refrigerant is fully liquid.

WebMay 18, 2024 · To measure liquid subcooling: 1. Attach your gauge manifold to the liquid line service port. If you use a quick-connect fitting on the end of your hose, make sure it’s a low-loss fitting. I’ve seen some quick-connect fittings that allow pressure loss, which can cause inaccuracies in the charging procedure. 2. WebJul 10, 2024 · Take the condensing temperature and the condenser outlet temperature, and the difference between the two is the amount of subcooling. “Let’s say the condensing temperature is 100°F. Put a thermistor on the condenser outlet, and let’s say that’s 90°,” continued Tomczyk. “So, you have 10° of subcooling.
