Guidelines for Evaluation of Cab Temperature

A guideline for evaluating the temperature environment of agricultural and industrial equipment cabs is presented. The average cab temperature is compared to the comfortable, slightly cool, and slightly warm areas on the 1972 ASHRAE comfort chart. A procedure for uniformly determining average cab temperature is outlined. The parameters to consider in a cab heat load calculation are reviewed. This indicates the relative importance of conduction, solar, and infiltration heat loads when designing air-conditioned cabs.
