15.15 A hospital in Denver, Colorado, requires heat- ing to 72F (22C) during the entire heating season. The heat load at-2.5F (-19C) is 10.0 MBtu/h (2950 kW), and the balance-point tem- perature is estimated to be 62F (17C). The boiler capacity (corrected for altitude) is 11.0 MBtu/h (3240 kW) with a full-load efficiency of 82%. Either write a computer program or use spreadsheet software to solve this problem using the bin data for Denver. The part-load equation for the boiler is 15 -Qi-= 0.10 + 0.90(PLR) What are the annual energy consumption, the annually averaged efficiency, and the annual PLR of the boiler?-(4) 15.15 A hospital in Denver, Colorado, requires heat- ing to 72F (22C) during the entire heating season.
