Fan convectors are a well-established terminal system for room temperature control. Most are installed with flexible or rigid ducts in gaps in the ceiling and serve a series of final outlets in the form of slotted, vortex or louvred diffusers. However, in most cases, these individual components are supplied by different manufacturers.

Accurate fan coil unit condo testing can show that the unit performs exactly as claimed, minimizing project risk and giving customers peace of mind, as well as helping to develop the best solution for a particular project.

Test facility meeting the stringent requirements of BS4856 Part 1 1972, Methods for testing and evaluating fan coil units, heating and cooling modules, and Eurovent fan coil unit thermal test methods 6/3-1996.

The chamber can test the heating capacity and air volume performance of four-pipe fan coil units with cooling and heating capacities up to 6 kW and airflow rates between 50 and 500 l/s. Horizontal and vertical units (with or without ducts) can be tested.

Future problems

Airside fan coil units are very popular, accounting for about a quarter of the market, with two basic designs available. The inlet or outlet valve options use a series of valves/valves to direct air through the heating, bypass and cooling zones to control the outlet temperature.

The transmission or potential energy loss of some fan coil units can exceed 500W in the bypass position.

The newly developed fan convectors reduce this energy loss significantly and in general the effort can be described as insignificant they also meet the new requirements of Part L.
