(54) | A room air cooling arrangement |
(57) A ceiling mounted room air cooling device comprises a longitudinal primary air channel,
a room air cooling coil, a mixing chamber for mixing cooled room air and primary air,
means for supplying primary air to the mixing chamber through the medium of an induction
effect which serves to suck room air into the device and to pass said air through
the cooling coil and into the mixing chamber, and one or more outlet channels through
which a mixture of cooled room air and the supplied primary air exit from said device.
The device is characterised in that the primary air channel is divided into two spaces
by a longitudinal air-permeable partition wall. The first space receives primary air
from an external source and is delimited from the second space with respect to flow.
The second space forms that part of the primary air channel in which the primary air
supply means is arranged in a partition wall or partition walls delimiting the mixing
chamber. The air-permeable partition wall preferably comprises perforated sheet metal.
The partition wall or walls between the second space and the mixing chamber will conveniently
extend generally transversely to the flow direction in the adjacent outlet channel. |
