Review
After determining the entering air conditions for the coil and the slope of the
SHR line, the coil curves were used to find the required supply air conditions.
This point (D) was established by the intersection of the coil curve and the SHR
line.
By knowing the design room conditions A and the required supply air
conditions D, the corresponding supply airflow could be calculated.
After the entering (C) and leaving (D) coil conditions were established, the
enthalpies for each were read from the psychrometric chart. These enthalpy
values and the previously calculated supply airflow were used to determine the
refrigeration load in Btu/hr or tons.
