A PT or pressure-temperature chart is an essential tool in a form of a table or chart, representing the relationship of pressure and temperature of a refrigerant to design and troubleshoot air conditioning systems. A refrigerant gauge is a device used to measure pressure and convert that into a temperature, thats all it does, some have clamps that measure pipe temperatures as well, but that is ALL it does, it does not tell you if the system is happy, if its working well. Log In My Account lq. Most of you know R-32 as a necessary component in the widely popular HFC blend known as R-410A Puron. This is also thelow-side pressure, assuming there is no pressure drop. It acts like a pump to create the circulation by compressing the refrigerant gas, creating a pressure difference that drives the refrigerant around the circuit in a continuous cycle. Iso butane is R600a , when you compare the change of temperature with pressure the change is drastic in the case of iso butane than in R134a An R12 to R134a refrigerant conversion chart is a tool used to properly recharge or convert a vehicle air conditioning system based on the refrigerant type Depending on the size of your system it pays to. 75 15.
