The 410a part of the gauge is reading 44 low and 106 for high.However, if you're talking about completely replacing R-22 with R-410a, the answer is also probably not. R-410a has to be charged at a higher pressure than R-22. Your old system may not be suited to operating at that higher pressure. The ultimate answer would be to consult the manufacturing specs for your equipment to see if they approve R-410a ...The fan cycling control will then start the fan when the pressure reaches the cut-in setting. Example: An R134a condenser operating in a 45° outdoor ambient temperature. When the head pressure drops to 90° condensing temperature or 104 psig, the fan shuts off. This is the cut-out pressure.

Low pressure refrigerant switches on Carrier HVACR typically open at 50 psi and close at 100 psi.Thank you for asking about your Volkswagen. On a 95 degree day, the low side should be reading at or around 35 PSI, so it sounds like the A/C is in normal working condition. Try checking the high-side PSI to see if it is abnormal. The high-side PSI reading on a 95 degree day should be about 240 PSI. Thank you!-BDPWhen connecting gauges, connect to the always-suction port on the low side. On quite a few systems, you can get your head pressure on the liquid line, but some systems may require you to connect to the discharge line to check the head pressure. A common rule of thumb is the 100-degrees over ambient rule; the temperature of the discharge line on ...R22 changes from a liquid to a gas in the evaporator coils of the air handler.

Explanation: The pressure of a gas is directly proportional to its temperature, according to Charles's Law. Therefore, to determine the approximate pressure of the storage cylinder containing R-410A at 80°F, we need to know the pressure of the gas at a known temperature.Good Subcooling Value for R-410A: Similar to superheat, the ideal subcooling value for R-410A can vary depending on factors like system design and operating conditions. However, a common target for R-410A systems is to achieve a subcooling value in the range of 8 to 15 degrees Fahrenheit (°F) or approximately 4.4 to 8.3 degrees Celsius (°C).The picture below shows a system running on a 85°F day that had 6 ounces of R-410A added. In the picture, the manifold valve to the blue hose is closed so the blue gauge is measuring the pressure inside the running system. The vapor pressure is 118 PSIG and because it is 85°F outside, the R-410A bottle pressure is 254 PSIG.I have a question regarding the 410A systems and there related pressures.

Due to the close performance, it is expected that R-410A line . size charts will work well for R ...Suction Pressure / EVAP DTD Rule of Thumb Another common old school rule of thumb is suction pressure should be close to the outdoor temperature in an R22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient.We can use the saturation pressure-temperature relationship for R-410A, which can be found in refrigerant property tables or online resources. Step 3/10 3. According to the saturation pressure-temperature relationship for R-410A, the initial pressure at 60°C is approximately 1960 kPa.
