Energy Efficiency Regulations

Regulatory definition

Large air conditioner, a commercial or industrial unitary air conditioner with a cooling capacity of at least 19 kW (65,000 Btu/h) but less than 223 kW (760,000 Btu/h). It does not include a single package vertical air conditioner.

Large heat pump, a commercial or industrial unitary heat pump that is intended for air-conditioning and space-heating applications and that has a cooling capacity of at least 19 kW (65,000 Btu/h) but less than 223 kW (760,000 Btu/h). It does not include a single package vertical heat pump.

Large condensing unit, a commercial or industrial condensing unit that is intended for air conditioning applications and that has a cooling capacity of at least 40 kW (135,000 Btu/h) but not more than 70 kW (240,000 Btu/h)
