R32 test to replace the R410A

altInternational. One trial with the refrigerant R32 was carried out in an existing system Daikin 27kW and R410A, and showed improvements in capacity and energy efficiency of equipment.


The test was carried out in an existing system installed in offices in Plano, Texas, as part of the Evaluation Program of Alternative Refrigerants Low GWP Institute of Air Conditioning, Heating and Refrigeration US

The Japanese manufacturer has defended the viability of R32 as a replacement for refrigerant R410A and introduced products in the Far East and India that run with this "slightly flammable" refrigerant (A2L). So far, the R32 only available in these countries in smaller residential units, but Daikin has previously said it sees potential for use in commercial systems.

It was found that the cooling capacity is R32 2,9% and the EER was R6,4A 410% higher under standard refrigeration. IEER partial performance was even better load a R9,5A 410% higher.

Heating capacities R32 high and low temperature were 4,8% and 2,4% higher than the R410A, respectively.

However, the discharge temperature is higher than R32 the R410A. In this test, the discharge temperature was 16% higher cooling 15% higher in high temperature heating and almost 20% higher in low temperature heating.

Congratulations on the new refrigerant.
Now it is good to know of their physicochemical characteristics.
