Factors based on 2.35 GMP per water circuit.
Specify GPM when ordering.
Table 1 indicates usual basic Unit Cooling
capacities at conventional operating conditions which
can be modified for variations in Refrigerant Temperature and Sensible Heat
Percentage by use
factors in Tables 2 and 3.
Heating capacities vary with Entering Air Temperature,
Steam Pressures and Water Temperatures
and can be modified by factors in Tables 4 and 5, interpolating for related
values within reasonable
range.
