AHRI 370 (SI/I-P): Sound Performance Rating of Large Air-cooled Outdoor Refrigerating and Air-conditioning Equipment

This standard establishes methods for determining the sound ratings of the outdoor portions of factory-made commercial and industrial Large Air-cooled Outdoor Refrigerating and Air-conditioning Equipment. This standard establishes definitions; test requirements; rating requirements; minimum data requirements for Published Ratings; and conformance conditions.

In Scope

AHRI Standard 370 applies to the air-cooled outdoor portions of factory-made commercial and industrial Air-cooled Outdoor Refrigerating and Air-conditioning Equipment. This equipment is covered by:

• AHRI 210/240, Performance Rating of Unitary Air-conditioning & Air-source Heat Pump Equipment,


• AHRI 340/360, Performance Rating of Commercial and Industrial Unitary Air-conditioning and Heat Pump Equipment,


• AHRI 365 (I-P) and AHRI 366 (SI), Commercial and Industrial Unitary Air-conditioning Condensing Units,


• AHRI 520, Performance Rating of Positive Displacement Condensing Units,


• AHRI 460, Performance Rating of Remote Mechanical-draft Air-cooled Refrigerant Condensers,


• AHRI 490 (I-P) and AHRI 491 (SI), Remote Mechanical-draft Evaporatively-cooled Refrigerant Condensers,


• AHRI 550/590 (I-P) and AHRI 551/591 (SI), Performance Rating of Water Chilling Packages Using the Vapor Compression Cycle.

Exclusions

This standard does not apply to the outdoor portions of unitary air-conditioning or heat pump equipment that fall within the scope of AHRI 270, Sound Rating of Outdoor Unitary Equipment (cooling capacity ratings of less than 10.5 kW (36,000 BTU/Hr)).
