Hello friends,
I am confused about Ashrae, thus I need to ask you about it.
I use 2006 ashrae and I think there is a problem in “Suction, Discharge and Liquid Line Capacities in Kilowatts for Refrigerant 404 a (single or High-Stage Applications)”. The problem is in the liquid line section at the header. It seems like this;
Liquid Lines (40 °C)
See note a
Velocity = 0,5 m/s ∆T=2 K/m ∆T=5 K/m
According to me, the ∆T’s are supposed to be 0,02 K/m and 0,05 K/m. Could you please confirm me which one is correct ? 0,02 – 0,05 K/m or the current ones (2 K/m ; 5 K/m) ?
Does anyone know the answer ? Thanks people.
