In the example of an R-410A packaged unit with a surrounding air temperature of 70°F, the pressure on both the high and low-pressure side of the system will be 201 PSIG. If a new R-410A refrigerant bottle had a surrounding air temperature of 70°F, the pressure inside the bottle would be 201 PSIG.The boiling point of R22 is -40.8 degree Celsius (-41.4 degree F). Due to its low boiling point this refrigerant was initial developed for the low temperature applications like domestic and farm freezers and in industrial refrigeration applications. Even at present R22 is extensively used in the industries for liquefaction of the gases like ...R22 you should probably be 62-74, and the head pressure probably 220-275. Thats just a 'guestimate'. The real way is to take pressures and line temperatures and then look on the r22 p/t chart, and then figure what is termed 'superheat' and 'subcooling'.4.8 (21) The refrigerant R22 has been phased out due to its ozone depleting properties.

Typical low pressure or suction side pressure for R410A is about 120 psi, varying by ambient temperature, here assuming 75°F, may vary by equipment and metering controls. 3. Typical high side pressure for R410A is < 600 psi at an ambient outdoor temperature of 95 °F, may vary by equipment. 4. As AC low side pressure surges beyond the recommended range, the cooling process and overall system efficiency are imperiled. Subpar cooling capacity culminates in discomfort, compromised humidity control, and protracted cooling cycles. Moreover, the compressor may face strain due to an excessive workload, potentially accelerating wear and tear.Instagram:https://instagram. plasma center athens georgiaboul floridales schwab hillsboro imbrierogers and hollands locations pressure is 6.154 in.Hg vacuum, or 11.674 psia (29.921 – 6.154 = 23.767 × 0.491 = 11.67).
