Program Scope

• This certification program covers matched variable refrigerant flow multi-split air-conditioner and multi-split heat pump systems, that comply with either the National Appliance Energy Conservation Act (NAECA) or the Energy Policy Act (EPACT) and use distributed refrigerant technology with cooling and heating capacities for outdoor units from 12,000 Btu/h [3508 W] to 300,000 Btu/h [87,692 W] and indoor units from 5,000 Btu/h [1,462 W] to 60,000 Btu/h [17,538 W]. Each indoor unit is designed to condition a single zone.
• This certification program applies to variable refrigerant flow multi-split systems consisting of the following matched components: a) an outdoor unit with single or multiple compressors or variable capacity compressor or with a variable speed drive; b) indoor unit(s) that have a coil, air movement device intended for single zone air distribution, and a temperature sensing control; and c) a zone temperature control device.
• The multi-split systems covered in this standard are VRF Multi-Split Systems and Heat Recovery VRF Multi-Split Systems. Included are multi-split, matched system air-conditioners and heat pumps irrespective of their type of electric power source, or secondary fluid (e.g. air-to-air or water-to-air).
