NEW PROJECTS AND DESIGN
Queen Elizabeth Hospital
7.05. The main switchboard and the emergency generator were successfully installed and commissioned, the former having a distribution capacity of 3,500 KVA and the latter 680 KW. These are the largest single pieces of equipment of these categories installed in Government premises to date. The mechanical and electrical services were completed in time for the official opening of the hospital in September, 1963. During the following six months, the whole of the extensive plant and equipment was gradually brought into full operation. The total steam capacity of the boiler plant is 88,000 pounds of steam per hour which is distributed throughout the building to some 360 steam-consuming appliances such as sterilizers, kitchen equipment, laundry machinery, calorifiers and two 685-H.P. turbine-driven compressors which provide a total of 1,500 tons of refrigeration for air-conditioning purposes. The steam distribution itself involves over 6 miles of pipework of diameters varying between 12" and 1/2". The boiler fuel supply is maintained from two 280-tons-capacity tanks which are filled by means of a 6" diameter main running 14 miles from the Hung Hom reclamation site where the oil is delivered by barge. Also located at Hung Hom are the pumps which deliver 4 million gallons of sea-water per day to the hospital to cool the refrigeration condensers. A further major installation of its kind is the hospital compressed air system which is served by three 100-c.f.m. air compressors and distributes air to draw-off points throughout the building. Work on the laundry and the installation of the large radiological machines continues.
Queen Mary Hospital
