Title: Summerization of Construction Equipment
text: This paper discusses some of the problems encountered in “summerizing” or air conditioning a cab used on construction equipment. The environmental conditions of high temperature and high relative humidity combined with severe dust shock and vibration conditions affect the design of components. Components discussed are compressors, condensers, evaporator coils, filters, air ducts, air diffusers and heaters. Installation for ease of maintenance and replacement is emphasized.
