Variable Refrigerant Flow (VRF) Multi-Split Air Conditioning and Heat Pump Equipment

Resources

Program Scope

This certification program applies to production models of 50 and 60 Hz VRF systems that meet the following criteria and: Include multi-split system air conditioners and heat pumps irrespective of their electric power source or secondary fluid (e.g. air-to-air or water-to-air) with cooling capacity equal to or above 65,000 Btu/h for air-source systems, and all cooling capacities for water-source systems.

  • Use distributed refrigerant technology with cooling and heating capacities for outdoor units up to 760,000 with indoor units from 5,000 Btu/h [1,462 W] to 144,000 Btu/h [42,202 W]. Each indoor unit is designed to condition a single zone;
  • Consisting of the following matched components: a) an outdoor unit with single or multiple compressors or variable capacity compressor; b) multiple indoor units; and c) a zone temperature control device.
