1.1
Outline
1.1.1 About Refrigerant R410A
Characteristics of new refrigerant, R410A
1. Performance
Almost the same performance as R22 and R407C
2. Pressure
Working pressure is approx. 1.4 times more than R22 and R407C.
3. Refrigerant composition
Few problems in composition control, since it is a Quasi-azeotropic mixture refrigerant.
1.Non-azeotropic mixture refrigerant : mixture of two or more refrigerants having different boiling
points.
2.Quasi-azeotropic mixture refrigerant : mixture of two or more refrigerants having similar boiling
points.
3.The design pressure is different at each product. Please refer to the installation manual for each
product.
