ABSTRACT
W. Jones suggests that the art of plant location is to minimise the lengths of piping and ductwork that link the plant with ancillary components or terminal units, while ensuring proper performance. Because copious quantities of outside air are essential and its free flow to and from the tower must not be compromised by the proximity of neighbouring structures, the best location for a cooling tower is often on a roof. Air-handling plantrooms may accommodate a packaged air-handling unit for supply air; an extract fan and motor set; ducts for supply, recirculated, discharge and fresh air; silencers; duct-mounted heated batteries; controls; switch-gear; pumps and lagged pipes. With high-rise buildings the cost of duct-work and the space it occupies can be minimised by putting airhandling units in a plant room on an intermediate floor, specially intended and constructed for the purpose.
