R22 low side pressure at 70 degrees.

One for heating and one for cooling. At a given outdoor ambient, indoor wetbulb and dry bulb, the suction and discharge pressures should intersect on a graph at specific temp readings along a curve on the graph. Also, as Houston said, there should be a desired subcooling reading at the outdoor unit.The low side pressure when the compressor is running is a feature of the compressor's own pumping power combined with the properties of whatever device is being used to …65 psi R22 saturation temp is 37.5. Hard to believe it’s cooling the box at that saturation temp, maybe keeping it in the low 40s. Also you have no superheat. I’d expect to find high subcooling. Sounds likely overcharged. The reason the suction pressure doesn’t change when the solenoid valve closes is because the compressor doesn’t stay ...The saturate pressure-temperature curves of R417a, together with R22, R407c, and R410a, are plotted together in Figure 2 that shows the pressure level of R417a to be about 10% less than that of ...r22 system, 3 ton condenser, high side pressure is415/156, low side is 85/50, the air temp is 98,wet bulb is 71, vapor line temp. is 72. the subcooling is correct. but temps and pressure are to high. … read more

The low side pressure in your air conditioning system should drop down significantly when your engine is running and your AC compressor is cycling on. When the compressor shuts off or you turn your car off the pressures in the system will equalize between the high and low side so the low side pressure will read much higher. ...

Johnstone Supply is a leading wholesale distributor for HVACR equipment, parts and supplies available and in-stock at local branches.The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.

And to add, the suction on the unit with the low high side pressure is high, about 100 psig. And the suction on the unit with the high pressure high side is normal and super heat is correct but the subcooling is way off. The compressor's not running on the 100 psi low/100 psi high unit and the other is probably overcharged. Reply.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.
