Both older R-22 and R-134 operate at lower pressures than R-410A. R22 Refrigerant Pressure Rules of Thumb Typical Off, Low, High side R22 Pressures & Temperatures. On a properly-charged and working air conditioning system using R-22 refrigerant. Low pressure refrigerant switches on Carrier HVACR typically open at 50 psi and close at 100 psi.When I got the call back for high pressure I decided to jump out the pressure limit switch and observe the startup pressures with my gauges. I was amazed to observe that this unit starts on the high side at about 550 psi (which seems extraordinarily high) and then drops down to a normal operating pressure within about 15 seconds.R32 has a GWP of 675, approximately 70% lower than the GWP of R410A, which is 2088. Due to its single-component nature, R32 heat pumps use 20% less refrigerant than R410A heat pumps. Consequently, their operational costs are lower. R410A refrigerant cannot be reclaimed like R32, as the former is a blend.This is a chart that tells you what pressure R407C should have at -49°F to 150°F temperatures. Using an R407c pressure temperature chart you can also check what temperature a saturated R407c liquid and vapor should have at -10.4 psig to 437.5 psig pressure.

A common rule of thumb is the 100-degrees over ambient rule; the temperature of the discharge line on a running system should be 100-110 degrees above the outdoor air temperature.You can pressurize a system to 150 psig with refrigerant and use an electronic leak detector locate the general area of any leaks, then a bubble solution to pin point the leak. That is how it is properly done. Some systems allow higher than 150 psig test pressures, if so, its stamped on the name plate of the system.I originally wrote this guideline back in 2003, and truthfully, not much has changed since then in regards to checking a heat mode charge on a heat pump. Step #1 - If there is any frost on the outside unit, get it completely defrosted first. Step #2 - Check all the obvious things first, filter, coils, blower wheel, etc.So they say to only charge 410a as a liquid.

Normally if system is running you can use the compressor to suck the refer in through the low side. With 410a I only do 6-8 ...The manual states that the design pressure should be 255/465 psi. The running pressure is about 200 on the fluid line and 150 on the exhaust line. This is what my installer feels like a good pressure. However, the company that sold me the system said that the pressure should be ~100psi on either line.

Using the previous examples comparing the operating pressures of an R-22 system to an R-410A system, the. R-22 system would have a compression ratio of 3.02:1, while the R-410A system would have a compression ratio of 2.98:1. The actual efficiency gains from R-410A are due to its superior thermodynamic values over R-22.

Using the temperature rise method (CFM = KW (Volts X Amps) X 3.413 divided by (Temp rise X 1.08)), check the airflow. Using the manufacturer's coil specification sheets, confirm the pressure drop across coils. The airflow measurement is used to find the evaporator load, so it must be accurate. Check the system operating pressures.
