Military combat vehicles differ in many ways from civil automotive vehicles because of their aim of usage and
structure. One of these differences is using spot cooling technic for the air conditioning system in the vehicle.
However, the A/C system in these vehicles is driven by the engine of the vehicle, like in civil automotive vehicles.
When the engine of the vehicle is off, the A/C system does not work as well. But in some conditions, the military
personnel in a military vehicle may need to work on some duties for some period of time without running the
engine of the vehicle. So, military personnel need a secondary system that creates A/C effect for that period of
time. In this study, an analytical model is prepared to determine the total amount of heat transfer value that
should be removed from the personnel by spot cooling with different properties of blowing air to help in
designing this required A/C effective system. This analytical model is validated with an experimental setup that
simulates the conditions of a sample military combat vehicle. This validated analytical model has been carried
out with respect to different blowing air properties and the range of distances between the louver and the
personnel. The values that provide the minimum required amount of heat transfer to be removed from the
personnel are determined and used to create thermal balance curves. These curves can be used to design a new
A/C system to make military personnel comfortable in the vehicle.
