Hello,

Have an office building using chiller, AHU and HRW for PAU. What is the most important data of HRW?

- what are different between 02 below models, which one is better.

Outdoor - Leaving Temp. (Db/Wb) ºC - 27.0/19.0 Efficiency %77

Outdoor - Leaving Temp. (Db/Wb) ºC - 27.9/21.7 Efficiency %78.2


Many thanks

The first is the most efficient - the lower the Wb the better the heat transfer

Thank you very much for you reply, but what about the efficiency? the software tell me that the second one has a higher efficiency than the first one. Why?
