Thermodynamic properties of R22, like vapor volume, enthalpy and entropy at pressures from 30 to 260 psia. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system. A tyre pressure monitoring system (TPMS) uses either a direct sensor inside your valve stem or a combination of both software and other existing sensors in your vehicle to let you know when your tyre pressure is outside a safe range of pressures. If the pressure falls below a manufacturers specified limit (usually 25% of recommended pressure) an …
