R22 low side pressure at 70 degrees.

Usually with our R290 refrigerant, charging can be done by bringing the low side pressure up to a point of about 10 pounds below the outside air temperature. At 80 Degrees F. bring the pressure up to approximately 70 lbs. This works quite well up to about 85 degrees. Above that, we prefer the pressure to be 15 lbs below the outside temperature.

1. Optimal Cooling. When the low side pressure operates within the recommended range for 410a, your system can efficiently absorb heat from your indoor environment. Any deviation from this range might compromise the cooling efficiency, leaving certain areas less cooled than others. 2.High pressure line actual temperature = 107F (subcooling ~4f) Suction line gauge reading PSI/temp = 70psi/41F. Suction line actual temperature = 50F (superheat ~9F too low) Air exiting indoor vents = 54F. Cold air return = 74 (diff = 20F) Bottom line: I am now seeing too little superheat, only 9F.I have an R22 system with a 30 degree low side and a 112 degree - Answered by a verified HVAC Technician.

I got a pressure reading of 90 psi on the low side and 190 psi on the high side.The first thing to realize is that when a system is off and equalized, the system’s pressures on both the high side and the low-pressure side will match. 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.Jun 29, 2010 · You asked for the temperartures of the high side line and the low side line as they leave/return to the condensing unit. The high side line tempersture was about 90 degrees F and the low side line was about 60 degrees F. This unit is a 1990 conventional A/C system. Maybe after 20 years of good service, I should not be trying to repair the problem. Instagram:https://instagram. smoke test in chicagodog ate multivitamin gummybronson fast care locationshobby lobby purple ornaments At 318.5 PSI, the saturated temperature is 100°F. If you measure 118 PSI on the low-pressure side of the system, then you know that the saturated temperature of the refrigerant flowing through the middle of the evaporator coil is at 40°F. This is a useful number when combined with the temperature of the tubing near the pressure port. crumbl cookie baton rougegis venango county Jun 14, 2013 · With clean coils both inside & outside, an inside temperature of 75° with. 50% humidity, I would expect a low side of roughly 70 PSI, and an hi-side pressure of roughly 20-30° above outside ambient temperature.
