Load & DesignPregunta 2 de 110
One ton of cooling capacity is equal to how many BTU per hour?
a.6,000 BTU/hr
b.9,000 BTU/hr
c.12,000 BTU/hr
d.15,000 BTU/hr
Explicación
A ton of refrigeration equals 12,000 BTU/hr, derived from the heat needed to melt one ton of ice in 24 hours. This unit is the standard used to size air-conditioning and heat-pump equipment. A 3-ton system therefore provides about 36,000 BTU/hr of cooling.
