SEER (or SEER2) is a rating that describes what?
a.Furnace heating efficiency
b.The seasonal cooling efficiency of air-conditioning equipment
c.The refrigerant type
d.The duct leakage rate
解析
SEER, and the updated SEER2, express the seasonal cooling output divided by the electrical energy input, so a higher number means greater cooling efficiency. It is used to compare and select air conditioners and heat pumps. California energy standards set minimum SEER values.
