June 10, 2019

The Air Conditioning, Heating, and Refrigeration Institute (AHRI) has announced the publication of AHRI 1380 (I-P/2019): Demand Response through Variable Capacity HVAC Systems in Residential and Small Commercial Applications. The standard establishes test requirements, operating and physical requirements, minimum data for published ratings requirements, and nameplate data and conformance conditions for variable capacity Demand Response (DR) HVAC systems.

AHRI also published an addendum to AHRI 210/240 (2017): Performance Rating of Unitary Air Conditioning & Air-Source Heat Pump Equipment. The addendum has several changes, including modifications to required tests and calculations as well as added definitions. Both standards are available for free download on the AHRI website.
