REPORT SS-A - SYSTEM MONTHLY LOADS SUMMARYThis report is always generated by the program for each HVAC systemmodeled. The monthly peak cooling, heating, and electrical loads are printedalong with the cooling, heating, and electrical energy demand for the systemsummarized. This report is for comparison of monthly cooling and heating'needs for the HVAC system. DX cooling is reported here (for PSZ, PMZS, PVAVS,PTAC, and RESYS systems) but is not passed to the PLANT program.1. The title of the report shows the user name of the HVAC system beingsummarized (SYST-1).2. COOLING, HEATING, and ELEC are the three sections of this system levelreport.3. COOLING ENERGY (millions of Btu) is the monthly sum of energy (sensibleand latent) extracted by the HVAC system during the operation hours ofthe system and passed as a load to PLANT.4. MAXIMUM COOLING LOAD (thousands of Btu/hr) includes sensible and latentspace cooling loads, ventilation air, and fan heat. Because systemstart-up loads can be larger than continuous running maximum loads, oftenthe start-up loads are shown in this column. To the left of this columnare the day and hour of the peak cooling load along with the outside drybulb and wet bulb temperatures at the time of the peak.5. HEATING ENERGY (millions of Btu) is the monthly sum of heat delivered bythe secondary HVAC system during the operation hours of the system andpassed as a load to PLANT.6. MAXIMUM HEATING LOAD (thousands of Btu/hr) includes space heating loads,ventilation, and humidification. Again, the peak heating load is oftendue to start-up conditions after the system has been shut downovernight. To the left of this column are the day and hour of the peakheating load along with the outside dry bulb and wet bulb temperatures atthe time of the peak.7.ELECTRICAL ENERGY (kWh) is the monthly electricalconvenience outlets, and supply and return fans.consumption by the pumps is reported in the PLANTconsumption for lights,The electricalprogram.8. MAXIMUM ELEC LOAD (kW) is the monthly peak electrical consumption in aone-hour period for lights, convenience outlets, and fans for the zonesserved by the HVAC system.9. TOTAL is the annual totals for cooling energy, heating energy, andelectrical energy for the HVAC system.10. MAX is the highest monthly peak cooling load, heating load, andelectrical load.VII.S7 (Revised 5/81)
