6) The Bin Method is used to determine the energy usage
of 32 °F the number of occupied hours is 200. If the occupied building load is as follows:
in a building. For a bin with an average temperature
4o = 20,000 – 500 to Btu/hr
and the manufacturer claims that the unit heating capacity is given by
C = 150 to + 6000
Btu/hr
with a degradation coefficient of 0.2, determine:
a) the occupied part-load factor (PLF), and
b) the occupied run time in hours.
(18 minutes, 0.874, 8.48 hrs)
