摘要

CO2水合物浆作为新型两相载冷剂应用于蓄冷空调中,可以有效调节用电高峰,合理利用电能,拥有很好的应用前景.一般可以通过增压鼓泡的方法制得CO2水合物浆,制备方法简单节能,而且蓄冷特性出色,相变温度适宜.在此根据非牛顿流体的特点,综述了国内外关于CO2水合物浆流变方程的选择,列出了表观粘度和流变指数的计算方法,并指出CO2水合物浆具有优良的流动特性.%As a new type of two phase secondary refrigerant, CO2 hydrate slurry has a good application prospect in air conditioningrnsystem with cool storage for its efficient and reasonable shift of power peak. Usually it is produced by pressurization and bubblingrngas in a vessel which is simple and energy conservation. In addition, CO2 hydrate slurry has a good performance in cool storage andrnphase change temperature. According to performance of non-Newtonian fluids, this work summarizes the rheology equation of CO2rnhydrate slurry, lists the calculation method of apparent viscosity and rheological index and points out the excellent flow characteristicrnof CO2 hydrate slurry.
