Description

This Part of this British Standard deals with methods of carrying out thermal and volumetric tests on units intended for use with additional ducting containing fluid to air heat exchangers and incorporating their own electrically powered fan system. The units may be either for heating or for cooling applications and the latter may be with or without dehumidification under frost-free conditions. The tests are to be carried out on units in an essentially clean condition.

Units for use with additional ducting containing fluid to air heat exchangers and incorporating their own electrically powered fan system. For heating or cooling applications, the latter with or without dehumidification under frost-free conditions.
