7. COOLING CAPACITY (KBTU/HR) is either the value entered by the user forthe keyword COOLING-CAPACITY at the system level or is computed bySYSTEMS from the total cooling capacity (sensible plus latent) from thepeak loads. If the cfm chosen for the system is different from theuser-specified value of RATED-CFM, COOLING CAPACITY may reflect acorrection for off-rated performance.8. SENSIBLE (SHR) is the sensible heat ratio, i.e., the fraction of thetotal cooling capacity that is sensible cooling capacity at the peak ordesign condition, adjusted for RATED-CFM. If the user has not enteredCOOL-SH-CAP at the system level for a central system, this value iscalculated from a simulation of the conditions at peak loads, adjustedfor RATED-CFM.9. HEATING CAPACITY (KBTU/HR) is the maximum value for heating and again itreflects either the user input or a calculation from peak loads. Likethe COOLING CAPACITY, this value will be zero for zonal systems, wherethe capacity is shown at the zone level.10. COOLING EIR (BTU/BTU) is the electric input ratio for cooling and iseither taken from the user input or from the default. This value may bemodified if the supply cfm differs from the RATED-CFM. The same is truefor HEATING EIR.11. SUPPLY CFM is the calculated or input cfm for each zone. Only if theuser has specified a value for the ASSIGNED-CFM keyword in the ZONEinstruction will the value here correspond to the user input. The otherkeywords, AIR-CHANGES/HR and CFM/SQFT, will be accepted by SYSTEMS onlyif they are consistent with the user-supplied HEATING-CAPACITY andCOOLING-CAPACITY, and are equivalent to a cfm larger than that of theexhaust from or the ventilation to the zone. If so, the cfm-equivalentvalues of the keywords AIR-CHANGES/HR and CFM/SQFT will be rounded up tothe nearest 10 cfm. In any case, the ALTITUDE MULTIPLIER will be applied.12.FAN (KW) is the total of the zoneconsumption at design conditions.there are no zone fans.supply and exhaust fan electricalIn the example shown, this is zero, as13. MINIMUM CFM RATIO will reflect the user's input for the MIN-CFM-RATIO,unless that input is in conflict with exhaust or ventilationrequirements. In the absence of user input, SYSTEMS will calculate theminimum cfm ratio for those variable air volume systems for which it maybe less than 1.0 from the minimum cfm needed to meet the peak loads orthe user-specified or the calculated heating capacity.14. OUTSIDE AIR CFM reflects the user-specified outside air quantity enteredat the zone level. If OUTSIDE-AIR-CFM is specified, its value ismultiplied by the ALTITUDE MULTIPLIER and reported here. Otherwise thereported value is the maximum of the cfm-equivalent values of OA-CHANGESand OA-CFM/PER, rounded upward to the nearest 10 cfm and then multipliedby the ALTITUDE MULTIPLIER. For the actual amount of outside airdelivered to the zone for central systems, see OUTSIDE AIR above.VII.54
