I've got a situation where my subcool is a bit high (15 instead of the 8-12 range) but everything else is within design parameters (pressures, superheat, delta-t). Low subcooling means that a condenser is almost empty. High subcooling means that a condenser is over field of liquid. 1) The amount of refrigerant entering the metering orifice is the Outdoor Dry bulb. 2) The total heat of the air entering the evaporator coil is the Indoor Wet bulb. With 95 degrees outside air.no superheat, no subcooling. Here is the situation... Design pressures are 150/300psi with 12 degree subcooling... Actual conditions are 92Psi liquid at a temperature of 69F. High pressure side is at around 220Psi and about 12F BELOW saturation temperature. Cooling isn't really doing much indoors and runs constantly.The subcool will rise a bit too but since as the head pressure rises as well, the fixed metering device will meter more refrigerant into the evaporator no matter what the evaporator heat load is and the superheat will start to drop dramatically. This will have an effect on subcool to a small extent but not as much as the system with a txv.On many newer systems, especially high-efficiency systems, thermostatic expansion valves (TXVs) are used.

Subcool is always a very important calculation to take because it lets you know whether or not the metering device is receiving a full line of liquid. Typical ranges for subcooling are between 8 and 14° on a TXV system, …High discharge temperatures are caused from high compressor superheats, as a result of the starved evaporator. High compression ratios from the low evaporator pressure will cause high heat of compressions, thus high discharge temperatures. ... All of the liquid in the condenser will probably sit there for a while and subcool because of the …...
