ASHRAE 116

Abstract

This standard covers electrically driven, air-cooled air conditioners and heat pumps used in residential applications with cooling capacity of 65,000 Btu/h and less or, in the case of heating-only heat pumps, heating capacity of 65,000 Btu/h and less. <br>The methods of test in this standard are broadly applicable, but this standard provides cooling and heating hours in temperature bins for only the contiguous states of the continental USA. <br>This standard includes test methods for steady-state, cyclic, and part-load performance and methods for establishing seasonal performance. Equipment with single-speed, multiple-speed, variable-speed, unloading, or multiple compressors for ducted and ductless systems is included. <br>This standard does not apply to room air conditioners. See ASHRAE Standards 16 and 58. <br><strong>PURPOSE</strong> <br>This standard provides test methods and calculational procedures for determining the capacities and cooling seasonal efficiency ratios for unitary air-conditioning and heat pump equipment and heating seasonal performance factors for heat pump equipment.
