HVAC Charts - Your Source for Heating & Air Conditioning Charts and Supplies. R-22 Superheat & Subcooling Calculator. This tool is used for charging cooling systems that use R-22 Refrigerant. One side of this tool is a slide chart used for calculating superheat for a NON-TXV system and the other side is a slide chart used to calculate ...Superheat is a measured value. It is the difference between two temperatures. Superheat is measured as the difference between the actual temperature of the refrigerant vapor and the saturation temperature of the refrigerant at that same point. Superheat on the system's low side can be divided into two types: evaporator superheat and total (or ...According to the R-22 PT chart, this is equal to about 54°F. With the thermometer, we measured the saturated R-22 temperature of 45°F. Here is how we can calculate the R-22 superheat in this system: Superheat (R-22) = 54°F – 45°F = 9°F. The superheat calculator also gives us 9°F superheat for R-22 refrigerant.

In this video I do not go into the details of superheat and subco...Step 1 - Locate unit required subcooling From unit nameplate or literature Typical 8-12° F. Step 2 - Measure liquid pressure - convert to temperature. Step 3 - subtract required subcooling (Step 1) from converted temperature (Step2) - This is the required liquid line temperature. Step 4 - Measure liquid line temperature.

It is my understanding that the correct way to charge an R22 system without a TXV is by getting the actual superheat to match the target superheat. It is also my understanding that the target superheat in Fahrenheit is determined by the equation: Target superheat = (3 x Indoor Wet bulb temperature – 80 – Outdoor ambient temperature)/2.

This HVAC Video is- What Exactly are Superheat and Subcooling and How do you use each of them for Charging Air Conditioners to Check the Level of Refrigerant...R22 across the range of applications where R22 is com-monly found. Because the mass ˚ow of RS44B is similar to R22, RS44B can be freely used in systems both with a capillary, ˝xed ori˝ce or variable expansion devices. RS44B is compatible both with existing traditional lubri-cants, such as mineral & alkyl benzene oils, and also with 2. Then take the suction pressure and convert it to temperature on a temperature/pressure chart. Subtract the two numbers to get superheat. For example, 68 psi suction pressure on a R-22 system converts to 40°F. Let's say the suction line temperature is 50°F. Subtracting the two numbers gives us 10°F of superheat.
