What is BS 4857-1 – Thermal and aerodynamic performance of terminal reheat units about ?

Terminal reheat units are a type of air handling system that are generally used in conjunction with constant air volume (CAV) and variable air volume (VAV) systems, for efficient reheating of air in the occupied space. BS 4857 is a British Standards that discusses the methods for testing and rating of terminal reheat units, for air distribution systems. The main aim of the BS 4857 series is to provide manufacturers with best industry testing methods to determine the performance of terminal reheat units. BS 4857-1 is the first part of the BS 4857 series that describes methods of thermal and aerodynamic testing and rating for high pressure terminal reheat units with or without flow rate controllers. It describes the equipment required and gives instructions for the calculation, interpretation and interpolation of results.
