7.14. 83 additional parking meters were installed in the central district of Victoria bringing the total number of meters now installed and under regular maintenance to 376.
STEAM SECTION
7.15. A steam laundry installation complete with steam boiler, hot water boilers, soap boiler, cascade washing machine, steam presses, steam calendar, hydro extractor, etc. was installed in the Lai Chi Kok Prison. This installation was required urgently and was completed within four weeks.
7.16. 236 pressure vessels were overhauled and submitted for survey. These included 15 steam boilers, 2 heating boilers, kitchen equipment, calorifiers, air receivers, abattoir equipment, technical college equipment and 117 sterilizers, autoclaves and disinfectors in Government hospitals and clinics.
7.17. Seven new sterilizers, a new steam operated tilting kettle, and an autoclave were installed. A steam operated twin press with associated air compressor unit and cooling water tank unit was resited at Stanley Prison. The central autoclave room at Kowloon Hospital was re-arranged including the removal and re-installation of a gas fired sterilizer unit in 'M' Block and the installation of an experimental steam sterilizing sink in 'F' Block.
AIR CONDITIONING AND REFRIGERATION SECTION
7.18. The demand for air-conditioning and refrigeration installations in Government premises continued and as a result the responsibilities of the Section steadily increased.
7.19. The capacity of air conditioning installations completed under contract totalled no less than 1,835 tons of refrigeration, and work was in progress on other projects equivalent to a capacity of a further 2,774 tons of refrigeration.
7.20. Of the projects completed the most notable was that in the City Hall with a maximum simultaneous peak load of approximately 730 tons of refrigeration and an installed main plant capacity of approximately 680 tons of refrigeration. The plant consists of 4 reciprocating compressors driven by 180 H.P. motors and operating on the heat pump principle by reversal of the refrigerant circuit. The building is cooled by chilled water during the summer and heated by warm water during the winter.
