CIBSE approved CPD course
With over 60 years of experience within the Heating, Ventilation & Air Conditioning (HVAC) industry we have the know-how to communicate with our clients whom want to expand their knowledge of the products and services including technical and standard issues that come with this specialist trade.
This course explains the different types & functions of Fan Coil Units along with the benefits and components associated with them. Further learning objectives includes details on EC/DC technology, specific fan power (SFP), ducting & noise ratings (NR).
This course will cover the following:

Our dedicated R+D and Test facilities complement our in-house design and manufacturing capability to meet requirements placed by the most demanding customers.
Our combination of real-world simulation, expert staff and certified test equipment means you can be confident that all Diffusion units will perform according to plan in their target environments.
Using instruments calibrated and certified by BSRIA, we measure air volume, thermal and acoustic performance:
Air volumes are measured on a purpose designed flow-measuring rig utilising duct mounted flow measurement equipment. The rig measures air volume, motor amps, motor power and power factor simultaneously. Units can be mounted on the rig with the project ductwork and grilles fitted to give an accurate measurement of actual site external pressure drop.
The acoustic test lab consists of two 4mx4mx4m (64m3) reverberation chambers positioned end-to-end to allow measurements of the inlet/casing radiated and discharge levels simultaneously using full octave band sound measuring equipment.
The chambers can also accept the ductwork and grille layouts for a specific project to be fitted to the unit under test, so an ‘as installed on site’ scenario can be accurately acoustically measured.
The thermal test lab consists of a computer controlled thermal test system to accurately simulate the internal load conditions required for a given project.
The system also controls the operating parameters of the unit under test with regards to water flow rates, air volume and external pressure drop. It can be used for both heating and cooling in airside and waterside control formats. Heat exchanger pressure drops can also be measured and recorded, and all results are made available as comprehensive hardcopy output.
