SAE J169_198503

The purpose of this document is to establish air conditioning design guidelines that will apply to most systems rather than the specific design of any particular system. Operating conditions and characteristics of the equipment will determine the design of any successful system, and since these characteristics and conditions vary greatly from one application to another, the designer must determine the goals expected to be reached under the conditions encountered. To determine the capacity of such items as blowers, condenser fans, condenser coils, evaporator coils, filters, compressors, etc., will require the adherence to several guidelines, some of which are outlined in the following paragraphs. SAE J169 is being revised to develop a single document which would include all off-road equipment. The original document was written for construction and industrial equipment only. As part of the five year review the introduction was revised to delete reference to an automobile trip and the reference list was reviewed. Many of the references were part of the original document which were not deleted when the document was changed in later revisions.
