Global warming is caused by chlorine 01/11/10 Global warming is caused by chlorine The atmosphere is destroyed by chlorine. Refrigerants with chlorine CFC & HCFC Refrigerant without chlorine HFC www.saijo-denki.co.th

Assessing flammability Heat of combustion (MJ/kg.) A1 : incombustible A2L: rarely flammability A2: flammability A3: Severe flammability Burning speed (hrs./s) www.saijo-denki.co.th

The upper - lower limit flammable. The concentration of the ignition point of the refrigerant R32. Lower limit = 13.6 % Upper limit = 28.4 % Example Room’s size 3 x 3 m and 3 m of height = 27 cubic meter To ignite Required volume of liquid in the chamber up to 3.672 cubic meters. (Normally 9,000 BTU air conditioner with a refrigerant volume of 0.45 kg, which is a very small amount).

Suggest a common equipment between R-22 R-410A and R32 5/7/2018 Equipment for R32 Suggest a common equipment between R-22 R-410A and R32 Refrigerant pressure gauge Can not use between R-22 R-410A and R32. pressure gauge wire Can not use between R-22 R-410A and R32. Vacuum Can use between R-22 R-410A and R32. Note: the compressor oil between R22 to R410A and R32, when combined, acidic corrosion in the system to make it shorter lifespan of the compressor. (R32 oil is heat than R410A oil) www.saijo-denki.co.th

Pressure gauge and wire for R32 and R410A Pressure is more than R-22 R32 and R410A pressure terminal is bigger than R22 www.saijo-denki.co.th

The filling R32(single agent) No Turning R410A tank down when filling www.saijo-denki.co.th

The filling R410A (mixture) Turn R410A tank down when filling www.saijo-denki.co.th

Comparison the pressure at SUCTION pipe 60-80 PSI R-410A 130-140 PSI R-32 140-150 PSI www.saijo-denki.co.th www.saijo-denki.co.th
