DESCRIPTION
This standard 19/30358876 DC BS ISO 21773. Method of test and characterization of performance for energy recovery components is classified in these ICS categories:
  • 23.120 Ventilators. Fans. Air-conditioners
  • 91.120.10 Thermal insulation of buildings

This standard prescribes the methods for testing the performance of air-to-air heat/energy exchangers when used as devices to transfer heat or heat and water vapor between two airstreams used in ventilation systems. This standard prescribes methods to characterize the performance of exchangers for use in calculation of the energy performance of buildings. The types of air-to-air heat/energy exchangers covered by this standard are:

  1. fixed-plate exchangers [also known as recuperators],

  2. rotary exchangers, including heat wheels and total energy wheels [also known as regenerators],

  3. heat pipe exchangers using a heat transfer medium, excluding those using mechanical pumping,

This standard does not provide a method for measuring the response of exchangers to the formation of frost.
