ASHRAE 206 ADD A
Method of Test for Rating of Multi-Purpose Heat Pumps for Residential Space Conditioning and Water Heating
Year: 2014
Abstract: FOREWORD
Addendum a changes the intermediate compressor speed for the intermediate heating test from 1/2 of the speed between minimum capacity (k = 1) and the speed for maximum capacity (k = 2) to 1/3 for variable capacity systems. This change brings the testing for variable-capacity air source systems under Standard 206 into agreement with ANSI/ASHRAE Standard 116-2010, Methods of Testing for Rating Seasonal Efficiency of Unitary Air-Conditioners and Heat Pumps. It also changes the intermediate compressor speed for the intermediate heating test from 1/2 to 1/3 for variable-capacity liquid-source and variable-capacity direct geoexchange systems to keep them consistent with the variable- capacity air source systems. The entering water temperature for ground-loop variable-capacity equipment and the entering refrigerant temperature for direct geoexchange variable- capacity equipment is changed from 2.5°C (36.5°F) to 1.7°C (35.0°F) for the intermediate speed heating test to make them consistent with the change in speed. These changes are reflected in Tables 10.7a, 10.7b, and 10.7c
Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and (for deletions) unless the instructions specifically mention some other means of indicating the changes.
