Common Questions

1
What is 1 Ton of refrigeration?

One ton of refrigeration (TR) is the cooling capacity required to melt 2,000 pounds (1 short ton) of ice in 24 hours, equivalent to 12,000 BTU per hour.

2
How do windows affect cooling load?

Windows contribute significantly to heat gain through solar radiation (especially West-facing) and conduction. High-performance glazing can reduce this load by 30-50%.
