ANSI/ASHRAE 206-2024
Method of Testing for Rating of Multipurpose Heat Pumps for Residential Spece Conditioning and Water Heating
Provides uniform test methods and calculation procedures for establishing the efficiencies of multipurpose residential heat pumps for space conditioning, water heating, and/or dehumidification. Specifies the test equipment for performing such tests, the data required and calculations to be used, and lists and defines the terms used in testing. The procedures in this standard may be used as a basis for establishing efficiency ratings for such equipment and for estimating annual energy consumption. Covers electrically powered unitary integrated appliances that provide combinations of space conditioning, water heating, and/or dehumidification functions. The equipment to which this standard applies may have the capability to heat water and/or to perform space dehumidification without requiring the simultaneous performance of space conditioning. It addresses air-source, water-source, ground water-source, ground-source closed loop, and direct geoexchange equipment. It applies to air-source equipment rated below 65,000 Btu/h (19,000 W) and water-source, ground water-source, ground-source closed loop, and direct geoexchange equipment rated below 135,000 Btu/h (40,000 W). The method of testing in this standard is broadly applicable, but this standard provides cooling and heating hours in temperature bins for only the contiguous states of the continental USA. Includes test methods for steady-state, cyclic, and part-load performance and methods for establishing seasonal performance. Equipment with single-capacity, multiple-capacity, and variable-capacity, or multiple compressors is covered. The equipment to which this standard applies may be ducted or ductless, but is limited to forced air space conditioning.
