Only the DB and WB temperatures determine the target superheat. Here is the formula we use to calculate superheat: Target Superheat = (3 × TWet Bulb ...R410A runs at a higher pressure than R22 does, so a system designed for R22 cannot use R410A. If you put R410A into an R22 system, then the compressor and other components could rupture – completely ruining the system. Another difference between the two refrigerants is that R410A is able to absorb more heat than R22 refrigerant.

When your compressor has both a low head pressure and a high suction pressure your refrigeration equipment is still running, but the temperature is dangerously ...An R-22 evaporator coil operating in A/C mode, will run at approximately 70 PSI. An R-410a coil, conversely, at the same conditions will run at 130 PSI. Almost double the pressure. At first glance this looks concerning. But remember, R-22 coils are typically tested to 300-400 PSI, which is a much higher pressure than R-410a will ever run on the ...Yep, put in a R410A metering device. And convert back to R410A. There are still lots of people afraid of the higher pressures of R410A. So may have been done to keep pressures lower. others thing R410A compressors pump more refrigerant, to get the higher pressure, and think that used for R22 it will be more efficient.

With 410a heat pumps is there a recommended suction pressure. For example with R22 air-con systems I always aim for 400 suction and 1500 discharge and similar with 407c systems. I have been told to aim for round the 100 psi/700kpa mark with is about 0 degree C Was just curious for fault finding purposes. Cheers in advance, chris.
