The Demand for Air-Conditioning After the War (Continued from page 9) code regulations in effect do not require such an attendant. This type of machine can be started and stopped from the manager's office, if desired. We also shall have the reciprocating type of multi-cylinder refrigerating compressor which can be made fully automatic, thereby obtaining either a system of chilling water' and then pumping the water to the conditioner, or using direct expansion. The selection of any refrigerating machine requires careful planning with regard to fulfilling the conditions called for in municipal codes for the installation of refrigerating equipment ; and where no such code is in effect, the Saftey Code for Mechanical Refrigeration, sponsored by the American Society of Refrigerating Engineers and adopted under the rules of the Air Conditioning Association, should be followed. This Safety Code was developed over a period of many years and is, as it states, the Standard of the American Standards Association. Theatre owners would be well advised to have all their installations meet the above Safety Code, since it behooves the theatre industry to take every precaution to make their properties safe in all respects for the use of the public. COST EXPECTATIONS The actual cost of a suitable system for a theatre in the post-war era will undoubtedly be somewhat higher due to increased cost of labor and probable increased cost of materials. This will be more or less in line with what the specialists in building construction have forecast, and it is to be expected that the skilled labor used for installation purposes will require a higher hourly rate than before the •war. In the reconversion period, it will be difficult to predict the performance of labor due to the fact that such labor will not be available when needed. The added cost of materials undoubtedly will be reflected in this period as the maximum price regulations are removed. The increase may be very slight, but it is not to be expected that, by any miracle, the total cost can be less than before the war. The air-conditioning installations in both new and existing theatres after the war will have to satisfy high standards of comfort and reliability, at a minimum operating and maintenance cost. It surely should not be the theatre owner's idea to save any small extra first cost necessary to insure these results. We know now what those standards are, and how to achieve them. The higher standards of air-conditioning that are the present trend today, after more than twenty years of experience, will still be the guide for the theatre man after the war.
