AHRI 1230 (I-P): Performance Rating of Variable Refrigerant Flow (VRF) Multi-Split Air-Conditioning and Heat Pump Equipment

This standard applies to variable refrigerant flow (VRF) multi-split air conditioners and multi-split heat pumps using distributed refrigerant technology, including all capacities of VRF water-source heat pump systems and VRF air-source systems with cooling capacity ≥ 65,000 Btu/h, as defined in Section 3, and referenced as the “Basic Model.”
Note: In the event that this standard is required to demonstrate regulatory compliance, stakeholders must abide by all published requirements applicable to the regulated product. For example, for products that contain one or more design characteristics which either prevent testing according to this standard or cause this standard to evaluate the equipment in a manner unrepresentative of its true energy consumption characteristics, DOE requires the manufacturer to submit a petition for waiver, which would include an alternative method of test.

This standard applies to VRF systems defined in 3.47.
