Background technology
Material, when undergoing phase transition, can discharge or absorb a large amount of heats, and before and after phase transformation, material is out of phase temperature-resistant.Phase-changing energy storage material is exactly the engineering material utilizing this characteristic of material to apply.When ambient temperature is too high, phase-changing energy storage material, by absorbing the heat of surrounding environment, completes the transformation of low-temperature phase to high-temperature-phase, and holding temperature is stablized simultaneously; When ambient temperature is too low, phase-changing energy storage material, by completing the transformation of high-temperature-phase to low-temperature phase, discharges the heat of absorption simultaneously, thus holding temperature is stable.When phase-changing energy storage material is abundant, this characteristic can be utilized to maintain the temperature stabilization of surrounding enviroment, avoid environment to occur temperature fluctuation.
Given a certain amount of phase-change material, when the total amount of heat that phase-change material absorbs will be slightly less than total amount of heat needed for the complete phase transformation of phase-change material, phase-change material cannot all complete complete phase transformation, be in the state of two-phase coexistent.In this case, the temperature Tp of phase-change material will keep constant.The inlet temperature T1 controlling heat-conducting medium is constant, and simultaneously because the temperature Tp of phase-change material is constant, the derivation temperature T2 of heat-conducting medium also will keep constant.Like this, the turnover temperature difference T of heat-conducting medium will keep constant.Under the condition of heat-conducting medium homogeneous constant, its thermal capacitance C also will be a steady state value.Therefore, the heat Qe that heat-conducting medium can be derived will depend on the quality m of the heat-conducting medium participating in conduction process.Due to density
constant, quality m is proportional to volume V.Therefore, the heat Qe that heat-conducting medium can be derived determines by the heat-conducting medium volume V participating in conduction process.When the conduit cross-sectional area S exporting heat-conducting medium is constant, the volume Vt flow through in the unit interval will be determined by flow velocity ν.As can be seen from formula, when thermal conduction time is constant, coutroi velocity ν just can control the heat Qe that total heat-conducting medium can be derived.
