Measuring R22 pressure on a hot day in our air conditioner. After the PT chart for R22 refrigerant liquid gas, we will look at more of these examples. We will also describe some of the other physical properties of R22 like liquid and gas density, triple point temperature, critical pressure...
It is known from the second law of thermodynamics that, for reversible or irreversible processes, dug + Pd(1/ρ) is equal to the absolute temperature times the differential change of the entropy of the gas, Tds. That is: (2.23)dPρ+gdz+VgdVg+Tds−dqheat=0 Tds – dqheat is equal ...
The pressures in the PT chart are expressed in psig or gauge pressure. That’s very practical; we always use a pressuregauge meterwhen measuring the pressure in refrigerant lines. Note:R134A is chemically named 1,1,1,2-Tetrafluoroethane. For on-site use, we include aprintableR134A PT chart...
