Abstract
The proposed paper establishes a standard for load control of the air conditioning system and leak detection, for Trucks, Tractors, Harvester, Sprayers and Construction Machines. Also develop tests to measure the performance of air conditioning system in product audits.
These processes are focused on mass production and not for repairs.
The target, is establish an parameter objectively, for the comfort conditions offered by air conditioning systems, because the field claims, generally are subjective.
All test and controls are designed for, ecologic fluid. R-134a
In this paper, parameters are shown to directly control, the comfort provided by the air conditioning system of Agricultural Equipment, Construction and Industrial Vehicles, taking measurements of temperature inside the cabin and ambient conditions. Also, we have indirect parameters, for comparison with the internationally established comfort zones by ASHRAE organization for inside a cabin. Taking temperature measurements in louvers, and pressures in the air conditioning system (low pressure and high pressure).
The indirect measurements are especially important when there not is optimum environmental conditions for direct reading or, there not is a climate chamber where you can reproduce ideal ambient conditions.
