Load & Design第 14 / 110 题
If a home has a calculated cooling load of 30,000 BTU/hr, what nominal equipment size is the closest match?
a.2 tons
b.2.5 tons
c.3.5 tons
d.4 tons
解析
30,000 BTU/hr divided by 12,000 BTU/hr per ton equals 2.5 tons. Manual S guides selecting a unit whose capacity at design conditions closely matches this load. Choosing 2.5 tons avoids the humidity and cycling problems of oversizing.
