The widespread utilization of mechanical refrigeration systems by the theatre industry has to a large extent been responsible for acceptance of comfort air conditioning and the many improvements which have been of benefit to the user of air conditioning equipment. The large theatres were the first to proclaim the advantages of their air conditioning installations, many of which operated without adequate temperature control thus creating a wonderfully cold inside for the patrons, along with a delightful blast of cooled air covering the sidewalk area in front of the theatre. The small neighborhood theatres necessarily adopted air conditioning and were forced to economize on operation and installation costs due to their seating capacity.

The outlying theatre can use package type unit air conditioners which are completely self-contained air conditioning systems, In addition to capacity for cooling, they are equipped with fans for air circulation and ventilation. they accomplish dehumidification. and are also equipped with filtcrs to clean the air. They will also supply heating and humidification by the addition of standard accessories, and are so constructed that automatic tempe'aturc and humidity control can be utilized.
