R22 low side pressure at 70 degrees.

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.

A. To read AC gauges for R134A refrigerant, you will need to follow a few basic steps. First, ensure that the AC system is turned off and the pressure in the system is equalized. Then, connect the blue hose to the low-pressure side and the red hose to the high-pressure side.

Very high high-side pressure and very low low-side pressure indicates a restriction in the metering device.

Just for kicks, and for a learning experience, check the system vitals, and record the pressures, water temp entering and leaving the ...Using farthest outside scale on gauge. generally it should be around 225 on the high side and near 70 on the low. Keeping this in consideration, what should my Pressures be for …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.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.For recommended fan cycling switch settings, refer to Tables 2 and 3. Differential settings on fan cycling tem-perature controls should be no lower than 3.5°F (2°C). On fan cycling pressure controls with R404A, a differential of approximately 35 psig is recommended. On supermarket applications remote condenser fans may be cycled individ-ually ...An air conditioner with refrigerant R-22 has a low-side pressure of 70 psig and a temperature of 55 degrees Fahrenheit.

Suction pressure at this time was 70 psi and high side was 300 psi and high side needle on gauge was fluttering between approx 300 and 290 psi. Outdoor ambient temperature was 85 degrees. My question is - why is my pressure so high for an R22 system and why is the.The higher the GWP the more harm the refrigerant does to the climate. R-410A has a GWP of over two-thousand whereas R-32 has a GWP of only six-hundred and seventy-five. While R-32 isn’t perfect it is a lot better then R-410A. That is why we are beginning to see a rise of usage of R-32 in the European Union and here in the United …AC symptom #2: Low side pressure is too low, High side pressure is too low. Here are the possibilities. 1. This could be normal if outdoor temps are very low. Fix: None needed. Check again when the temperature rises. 2) Low refrigerant charge (most common cause). Fix: Check for leaks and repair.

Suction Pressure/Low Side. Suction pressure tells us several things. The first thing it tells us is what the boiling temperature of the refrigerant in the evaporator is. If the suction pressure is below 32° saturation temperature, the evaporator coil will eventually freeze.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 range of low side pressure for the R404 is nearby 20 psig in the usual case, and the inlet temperature of the compressor is 25° C approx. For the safe operation of a system with R404 refrigerant, the recommended superheat should be in the range of 20° C to 30° C.T/P chart says pressure is say R22 is 168 @ 90 degrees. How can the OP even have numbers as low as was reported? I would think the unit would have to be nearly empty of charge to have numbers this low.... as I understand it (studying for my 608 T2 exam, BTW ), if I have even a few ounces of R22 in a container at 90F, the pressure should be 168 ...Issued September 2018. The P70, P72, and P170 controls for low pressure applications are designed primarily for low-pressure cut-out control, pump-down control, and capacity control on commercial refrigeration and air conditioning applications.
