Experimental Study of Single Media Thermocline Thermal-Energy Storage

摘要

Experiments were conducted on a 1200 gallon single medium thermocline facility to determine the feasibility of the thermocline thermal energy storage concept on a large scale and to determine the relative importance of each of the five heat loss mechanisms present in such a system. The results of heat loss tests, static thermocline cool down tests and charge/discharge tests are presented. A simple one-dimensional model is proposed for the prediction of the temperature field during a cool down test in which a thermocline is present. The model agrees well with experiment.
