AHRI - 1230 I-P

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

active, Most Current
Organization: AHRI
Publication Date: 1 January 2021
Status: active
Page Count: 89
scope:

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 Variable Refrigerant Flow (VRF) Systems defined in 3.47.

Exclusions.

This standard does not apply to the rating and testing of:

• Individual assemblies, such as separate condensing units or indoor units;

• Air-conditioners and Heat Pumps, with capacities less than 65,000 Btu/h as defined in AHRI Standard 210/240;

• Water-source Heat Pumps (with the exception of Multi-split Systems) as defined in AHRI/ASHRAE ISO Standard 13256-1;

• Unitary Air-conditioners and Unitary Heat Pumps as defined in AHRI Standard 340/360, with capacities ≥65,000 Btu/h;

• Units equipped with desuperheater/water heating devices as defined in AHRI Standard 470;

• Commercial and Industrial Condensing units with a capacity greater than 135,000 Btu/h as defined in AHRI Standard 365 (I-P);

Energy Source.

This standard applies only to electrically operated, vapor compression refrigeration systems.

Purpose.

The purpose of this standard is to establish for Variable Refrigerant Flow (VRF) Multi-split Air Conditioners and Heat Pumps: definitions; classifications; test requirements; rating requirements; determination of Published Ratings; operating requirements; marking and nameplate data; conformance conditions; minimum data requirements for Published Ratings and calculations.

Intent.

This standard is intended for the guidance of the industry, including manufacturers, engineers, installers, contractors and users.

Specific interests include, but are not limited to, federal regulations, state regulations and efficiency standards developed by ASHRAE, International Energy Conservation Code (IECC), Canadian Standards Association (CSA), and United States Department of Energy (DOE).

Review and Amendment.

This standard is subject to review and amendment as technology advances.
