This calculator requires the use of Javascript enabled and capable browsers. This script determines the gas pressure based on temperature of R22 refrigerant. R22 or HCFC-22 is a single component HCFC refrigerant with low ozone depletion potential. It has long been used in a variety of air conditioning and refrigeration applications in a variety of markets, including appliance, construction, food processing, and supermarkets. Production of R22 in the United States is scheduled for phased termination, beginning in 1995, with R-410A offered by Honeywell as a phase replacement. In 2015, production is planned to be no more than 10% of the manufactured amount in 1994; termination of production worldwide by 2030. Enter the temperature in either F or C degrees and the returned result is the alternate temperature and determined pressure in Barg and psig. Barg is the gauge read pressure. The term gauge signifies that the pressure has been read from a gauge that actually measures the difference between the pressure of the fluid or gas and the pressure of the atmosphere. Psig is equal to psis at sea level (14.7 psi). Psig is equal to psia – 14.7 at sea level. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi. Now that I have indicated that, it relieves a lot of pressure...
