Cooling energy .16
An architect wants to design low-energy
buildings using little cooling. She wants
to place an earth pipe to cool the
ventilation air during warm periods. On
average the outdoor temperature during
the hot season is 33 [oC]. Normally this
air is cooled to 25 [OC] by a compression
chiller. With an earth pipe of 30 [m] the
warm outdoor air can be pre-cooled to
29 [OC]. How much cooling energy will
?be saved by using the earth pipe
% 100 O
% 50 O
% 35 O
% 25 O
