Vapor cycle system (VCS) with thermal reservoirs for reducing requisite VCS power and size with intermittent heat loads

摘要

A system for providing coolant to a heat load includes a first coolant reservoir providing coolant to the heat load and a second coolant reservoir receiving used coolant after passing through the heat load. The used coolant is refreshed by a cooling apparatus which receives the used coolant from the second coolant reservoir, cools the used coolant, and supplies refreshed coolant to said first coolant reservoir. The resulting dual reservoir system offers significant reductions in the size, weight and power of the vapor cycle system (VCS) equipment while providing for accurate temperature control of the coolant delivered to the heat load.
