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.
