1. Refrigerant R-32

2. Refrigerant R32 ???

3. 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

4. Assessing flammability
Heat of combustion (MJ/kg.)
A1 : incombustible
A2L: rarely flammability
A2: flammability
A3: Severe flammability
Burning speed (hrs./s)

5. The upper - lower limit flammable.
The concentration of the ignition point of the refrigerant R32.
Lower limit = 13.6 %
Upper limit = %
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 cubic meters.
(Normally 9,000 BTU air conditioner with a refrigerant volume of 0.45 kg, which is a very small amount).

6. Suggest a common equipment between R-22 R-410A and R32

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)

7. Pressure gauge and wire for R32 and R410A
Pressure is more than R-22
R32 and R410A pressure terminal is bigger than R22

8. The filling R32(single agent)
No Turning R410A tank down when filling

9. The filling R410A (mixture)
Turn R410A tank down
when filling

10. Comparison the pressure at SUCTION pipe
