The described apparatus supplements rather than disables the normal cooling process of human physiology by providing a large quantity of cooling air that is moved with significant perspiration evaporation velocity within a protective clothing ensemble. The disclosed apparatus provides cooling for up to five separate protected persons with capacities and cooling capability in excess of previously known personal cooling systems. Use of the cooling system for electronic and other military equipment is also disclosed.Other References
