Addendum ab has been developed to update the referenced Air-Conditioning, Heating and Refrigeration Institute (AHRI) standard for water-source heat pumps, to use a new annualized cooling metric, and to increase the minimum efficiency requirements in Table 6.8.1-15 for water-to-air water-source heat pumps.
