The refrigerant R407C is used as a replacement of refrigerant R22 due to similar operation properties for the two refrigerants. The experimental results displayed that the R22 refrigeration effect
The Daikin Premium Inverter can be retrofitted onto an existing R22 system by simply replacing both the indoor and outdoor units whilst retaining the field piping intact*. This allows for a convenient and cost effective way of upgrading an existing system that may be towards the end of its useful operating life. The Daikin Premium Inverter Series is equipped with three unique technologies that
If your unit runs on R22, you can replace it with a refrigerant alternative yourself or contact a professional to help you switch out the refrigerant. If the above options aren’t viable, you do have the option of installing a new, modern system in which an R22 alternative is already in place. R22 refrigerant replacement

The equipment used has a smaller footprint and the cooling capacity is higher. A high volumetric capacity also means less gas in a system for the same cooling results from R410A, making R32 more efficient. The running pressure is fairly similar to R410A so there should be no real difference in operating pressures when checked with gauges.
R32 can not be used as a drop-in replacement on existing R22, R407C and R410A systems. As an A2L refrigerant it is not suitable for retrofitting, and charging an existing system with R32 could increase unnecessary wear on the compressor, cause permanent and irrevocable damage to working component or even present a safety risk for the user.
I turned it on, connected the gauges and started adding R134a refrigerant. It took about 12 ounces of the original 13.6 ounces until it was cooling well and was not developing frost on the evaporator. The performance of the system is identical to with R22 refrigerant. It blows 38 degree air with a room temp of 75 degrees with the fan on high speed.

can i replace r22 with r32
