7.12. Among the projects still under construction were two of the largest yet undertaken by Government; that for the Queen Elizabeth Hospital will have a plant capacity of 1,500 tons, and that at Kai Tak Air Terminal Building 1,000 tons. The main refrigeration plant at Queen Elizabeth Hospital is of particular interest as the main compressor sets are to be steam turbine driven centrifugal units and these will be the first of their kind in the Colony.
7.22. Private architects engaged on Government projects continued to call on the services of the Section for the design, specification, and supervision of air-conditioning installations. Two installations of this category were completed during the year with a combined capacity of 807 tons refrigeration, and a further 4 schemes were in progress with a total capacity of 1,274 tons of refrigeration.

The task of maintaining this plant and equipment in efficient running order was carried out by staff from the workshops whose operations for the year embraced 902 overhaul tasks, 14,928 maintenance visits, and attendance to 1,700 fault calls. The air-conditioning and refrigeration workshops also carried out the complete re-installation of the air-conditioning system at Government House as well as 15 minor installations during the year. 254 new refrigerators were installed and 459 items of electrical appliances and equipment tested.
