1.R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan, Europe and USA.
Parts designed specifically for R-410A must be used as 410A operates at higher pressures than other refrigerants. R-410A systems thus require service personnel to use different tools, equipment, safety standards, and techniques. Equipment manufacturers are aware of these changes and require the certification of professionals installing R-410A systems.
Unlike alkyl halide refrigerants that contain bromine or chlorine, R-410A (which contains only fluorine) does not contribute to ozone depletion, and is therefore becoming more widely used, as ozone-depleting refrigerants like R-22 are phased out.The overall impact on global warming of R-410A systems will be substantially lower than that of R-22 systems due to reduced greenhouse gas emissions from power plants.
1.Because R410A and R22 pressures are different (R410A pressure is much higher than R22) and compressor oils are different.
Therefore, for the after-sales maintenance of the refrigeration equipment that is initially installed as R22 refrigerant, if you need to add or replace the refrigerant, you can only add R22. Usually you can't replace R22 with R410A (that is, you can't usually change it completely).
2.The Federal Clean Air Act restricts the sale and use of CFC and HCFC refrigerants to technician certified by an EPA.
With this purchase, you are stating that you are EPA certified or that this product will be used by a licensed technician. your payment will be used as your electronic signature.
3.No returns on refrigerant gases unless it is done in compliance with federal hazmat regulations and return shipping fees paid by the buyer.
