Both types of systems; that is, the centralized system and the packaged unit system are designed to give the same results-the same temperature and humidity. Both systems occupy practically the same space. The main difference is in the equipment itself.

As a number of neighborhood theatres are now or in the near future will be contemplating air conditioning, a few additional notes on the packaged-typo system perhaps would be helpful.

Packaged System

From the stadpoint of an investment, the packaged system has the advantage of employing standardized factoryebuilt equipment. The equipment can be considered as a fixture and a large percentage of the investment is in the form of the complete packaged unit with a known value. This equipment is movable.

In case of additions or alterations to the theatre, the packaged unit system can be easily added to without destroying any of the value of the original investment. Packaged units were developed for unattended operation. There is only one switch to turn on and off. Compact operating mechanisms are fully enclosed in an attractive cabinet. There is no exposed wiring and the unit is not subject to tampering. It can be employee operated as it is completely automatic and self-contained.

In case one of the units should fail, the system would still operate at slightly reduced capacity, no costly shutdown would result and the theatre would not be without air conditioning until repairs or replacements could be made. The units are quiet, vibrationless and economically maintained.

The compressor of each packaged air conditioner operates only as the heat load in its own area requires. This means that only as much horsepower is in use as the load requires, which fact is redected in operating costs.

Packaged units have been particularly designed to eliminate maintenance and service. The compressor is of the hermetically-sealed type with built-in motor. The entire compressor operates with a forced lubrication system in a bath of oil, thus providing long life and minimum maintenance, Some of these compressors have operated as long as 25,000 hours, or approximately 20 years service, without noticeable wear or. reduction in capacity, Any commercial service man can easily service this equipment and parts and service are immediately available. Records of operation on this equipment show a remarkable low operating maintenance cost, with very few failures.

During the past 20 years the American pattern of living has changed trcmendously. A continuous stream of new inventions and developments has fashioned entirely new concepts of what could be termed 20th century living. Modern air conditioning is one of many products enabling us to live better, in greater comfort, and to extract more enjoyment from our leisure entertainment.
