RSH = 100 kW (Room sensible heat) |
RLH = 25 kW (Room latent heat) |
OASH = 10 kW (Outside air sensible heat) |
OALH = 10 kW (Outside air latent heat) |
A) 0.72 and 0.8
B) 0.8 and 0.79
C) 0.79 and 0.8
D) 0.79 and 0.72
Correct Answer: B
Solution :
RSHF \[=\frac{RSH}{RSH+RLH}\] \[=\frac{100}{100+25}=\frac{100}{125}=0.8\] \[ESHF=\frac{RSHJ+OASH+BPF}{(RSH+OASH\times BPF)\,+\,RLH\,\,+\,\,OALH\,\,+\,\,BPF)}\] \[=\frac{100+10\times 0.15}{(100+25)\,+\,(10+10\,)\times 0.15}\] \[=\frac{101.5}{128}=0.79\]You need to login to perform this action.
