New Standard Showcases Efficiency of VRF Multi-Splits

The Air-Conditioning. Heating and Refrigeration Institute (AHRI) has for the first time created a standard to compare the efficiency of variable refrigerant flow (VRF) multi-split heating and cooling systems. The standard, AHRI 1230-2010, creates testing procedures for VRF multi-split systems, including those with variable-speed compressors. It covers VRF air conditioners and heat pumps using distributed refrigerant technology with heating and cooling capacities for outdoor units from 12,000 to 300,000 Btu/hr (3,500–90,000 W) and indoor units from 5,000 to 60,000 Btu/hr (1,000–20,000 W), with indoor units conditioning a single zone.
