Top 4 Reasons Why a Gas Furnace Short Cycles. Top 10 Thermostat Related Problems. Troubleshooting an Air Conditioning System with a Frozen Evaporator Most target superheat charts require indoor wet bulb and outdoor dry bulb measurements to yield a target superheat. Chart Properties Inside and Out Target superheat tables all have limits for the maximum and minimum outdoor dry bulb and indoor wet bulb temperatures used to obtain a target superheat.
Our Pressure Temperature Chart for the selected refrigerant is available for quick access; just use the button labeled (P/T). Use the refrigerant drop down for access to over 100 refrigerants. Plus and minus buttons add and subtract values in intervals of 1 to their related input fields. Superheat is the gas temperature above the saturated temperature. Increasing the fluid's pressure will raise the saturation temperature and decreasing the pressure will lower the temperature. These systems should provide a charging chart to properly charge their systems.

I was trying to calculate my target superheat when I ran into a bit of a problem. My indoor return wetbulb temperature is 60F and the outdoor ambient condenser temp is 90F.

Target SH = 1.5 iwb - 0.5 ambient + C The ambient term had to be subtracted in order to get the target superheat to drop as ambient increased. The iwb term is added (positive) because the target superheat has to rise as iwb rises. The relationships are in reverse directions from one another.
The target superheat value is at the intersection of the two. If you have to do repairs, recheck your temperatures. 2. Make your connections and toggle the gauge to show SUPERHEAT.

Before you begin making charge adjustments!!! Check your other readings Use the dew point temperature on the pressure/temperature chart to obtain the evaporator saturation temperature for superheat, and the bubble point temperature to obtain the condenser saturation temperature to measure subcooling. Wrap your thermocouples with insulation to obtain accurate pipe temperatures. Charging Charge through the suction side of the system. Use a commercial-type metering device in manifold hose to allow liquid to vaporize.
