An AC technician cannot simply add R-410A to a system designed for R-22. Since each type of refrigerant requires different pressure levels, they can’t be used interchangeably (however, R-421A refrigerant can be used as a substitute in R-22 systems). Retrofitting an existing system is often called a “drop-in” replacement. Systems with a low-GWP refrigerant can therefore have a larger charge than those with a higher GWP. R410A is a 50/50 mixture of R125 and R32. However, R410A has a GWP of 2088, compared to just 675 for R32. Daikin’s approach is to replace R410A with R32, along with a number of other companies. This means we can always find the best R22 replacement options for your business and air conditioning system, providing tailored solutions to match your needs and budget.

This eliminates larger VRF utilising this refrigerant. • The maximum charge of R32 before additional safety measures are required is just under 12kg. After this,additional safety measures must be It has a higher cooling capacity than R22, allowing for more efficient and effective cooling. R407C is another popular R22 alternative that has similar thermodynamic properties to R22 and can be used in many existing systems with minimal modifications. Other refrigerants such as R32, R438A, and R422D have also been developed as alternatives to R22. xwbdI.
