Abstract : This study reviewed various combat vehicle crew compartment thermal conditioning concepts. A preliminary selection of candidate systems, based on performance, power, size, weight, logistics, cost, and development status elimated all concepts from further consideration except for air cycle and vapor cycle. Both the air and vapor cycle systems underwent a preliminary design evaluation and a detailed trade-off. Conclusions drawn from the preliminary design and trade-off of these two concepts are: (1) On a comparative point basis, the air and vapor cycles are equivalent; (2) The vapor cycle has distinct advantages in power and cost; (3) The air cycle has distinct advantages in performance and weight for outdoor conditions other than the main design condition of 120 F dry bulb temperature and 3% relative humidity; (4) The air cycle has a slight advantage in size and logistics; and (5) The trade-off categories of reliability and noise, safety, simplicity, maintainability and other are comparable for the two concepts.
