Methods of testing for rating heat-operated unitary air-conditioning and heat-pump equipment.

Author(s) : ASHRAE

Type of monograph: Standard/Recommendation

Summary

This standard replaces standard ANSI-ASHRAE Standard 40-1980 (RA 1992). It provides test methods for determining heating and cooling output capacities and energy inputs of unitary air-conditioning and heat-pump equipment that is heat-operated. These test methods may be used as a basis for rating such equipment. Improvements from the previous version include the addition of environmental chamber design considerations, as well as changes to the air-enthalpy, external resistance and heat balance sections. In addition, chapters on the coolant heat-transfer fluid and refrigerant enthalpy methods have been added.
