(54) Ventilating system


(57) A ventilating unit has a diffuser coupled for delivering air into an accommodation space. The ventilating unit is arranged to draw air in from said roof space and deliver the air to the diffuser for delivery to the accommodation space. Air from the accommodation space is drawn into the diffuser and mixed with the primary air flow from the roof space so as to increase the temperature of the air prior to delivery into said accommodation space. Typically the only means by which the secondary air flow of air into the diffuser from the accommodation space is achieved is by means of the primary air flow over an aperture or slot.
