Dear Sir,
In response to your letter No* 2826-18/14 regarding
the cost of extending the air cooling to the upstairs rooms and
more offices in the Agency, our Engineering Department have made
a preliminary study and rough estimate of costs for your information.
The existing 5 ton unit with which you now cool three
rooms is not large enough to cool any more rooms and it appears that
the best plan would be to install two 20 ton units, one on each side
of the Agency, with a cold air and return air duct system to and
from each room to be cooled. The existing 5 ton unit would not
be required. One 40 ton unit would require long, difficult and
expensive return air ducts and is not considered as suitable as two
units.
I am returning herewith the two blueprints of the
upstairs and downstairs plan of the Agency on which we have indicated
a possible duct system for two 20 ton units. The cold air ducts to
the rooms are marked in red and the wannair return ducts to the units
are marked in green. This system is, of course, only a preliminary
suggestion and must be subject to further study by you or whoever
engineers the installation of the additional air cooling.
Based on approximately equivalent ceiling heights the
units would cool the following rooms :
