Abstract
This paper presents the results of performance
monitoring under real winter weather conditions, controlled laboratory
testing and computational fluid dynamics (CFD) analysis of a wall mounted
ventilation air inlet heat convector. For real winter weather monitoring,
the wall-mounted convector was installed in a laboratory room of the
Engineering Building of the School of Construction Management and
Engineering. Air and hot water temperatures and air speeds were measured
at the entrance to the convector and in the room. The hot water
temperature was controlled at 40, 60 and 80 °C.
The monitoring results were later used as boundary conditions for a CFD
simulation to investigate the air movement in the room. Controlled
laboratory testing was conducted in laboratories at the University of
Reading, UK and at Wetterstad Consultancy, Sweden. The results of the
performance investigation showed that the system contributed greatly to
the room heating, particularly at a water temperature of 80 °C.
Also adequate fresh air was supplied to the room. Such a system is able to
provide an energy efficient method of eliminating problems associated with
cold winter draughts.
Key words:
air inlet, heat convector, CFD, pre-heating, measurements.
