Related Standard 210/240
Standard 210/240 Scope
Related Standard 1230
The purpose of this standard is to establish, for Unitary Air-Conditioners and Air-Source Unitary Heat Pumps: definitions; classifications; test requirements; rating requirements; minimum data requirements for Published Ratings; operating requirements; marking and nameplate data; and conformance conditions.
Standard 1230 Scope
This standard covers matched variable refrigerant flow Multi-split Air Conditioners and Multi-split Heat Pumps using distributed refrigerant technology as defined in Section 3 of this standard. This standard 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 Variable Refrigerant Flow (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, type of refrigeration cycle, or secondary fluid (e.g. air-to-air or water-to-air).
Matched one-to-one or multi-split ductless-split air conditioner and ductless-split heat pump systems using distributed refrigerant technology for cooling and heating. Each indoor unit is designed to condition a single zone.
Ductless split systems consist 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.
There are five classes of ductless split systems:
- Ductless One-to-One Split Systems
- Space Constrained Ductless-Split Systems
- Ductless Multi-Split Systems
- Variable Refrigerant Flow (VRF) Ductless Split Systems
- Heat Recovery Multi-Split Systems
Included are ductless-split matched system air conditioners and heat pumps irrespective of their type of power source or type of refrigeration cycle.
Specifically excluded are products included in the scopes of other product sections of AHRI and room air conditioners and heat pumps.
