HOT AIR HEATING
ADDRESS AT TECHNICAL COLLEGE. An interesting lecture on the hygenics of ventilation was given in the Technical Col-' lege by Mr R. N. Andrew, president of the National Warm Air Heating Association of New Zealand. Mr Andrew dealt fully with the heating and ventilating plant recently installed in the new Majestic Theatre, Wellington. Three and a-quarter million cubic feet of fresh air is taken from the roof of the building, said Mr Andrew, every hour. The air is washed, filtered and then distributed throughout the building by means of two huge fans, each 9ft. 6ins. high and each driven by a 10-horse power electric motor. The air is thus changed throughout the whole building every 15 minutes. After leaving the fans, and before entering the theatre by the distributing ducts, the air is passed through a large brick chamber situated in front of each fan and in each chamber is placed an oil fired, warm air furnace. In winter the oil burners are started and the air delivered to the building is warmed, but in the hot weather cold air is delivered throughout the building. Another unique feature of the design is the fact that the installation is so arranged
that the tea-room and vestibules can be supplied with warm air and the theatre with cold air at the same time. Should the theatre develop a stuffy smell on hot muggy nights the plant is fitted with a zephyr atomizer, which injects a small quantity of lavender water into the fresh air which eliminates any sign of stuffiness. The unit will also spray disinfectant into the incoming air if desired, so that each morning the whole building is thoroughly disinfected from the top of the dome to the basement. This is the first theatre south of the line to be fitted with such a comprehensive system of heating, cooling and ventilation and the plant is very similar to the installations in the famous Roxy and Paramount Theatres in New York. Practically the whole of the Majestic plant was manufactured in Dunedin.
