摘要

本文介绍了一种3罐蓄热系统。该系统由冷油罐、蓄热罐和残排罐组成。冷油通过重力流入加热室,加热到所需温度后,机械恒温器打开,使热油流入储热罐。将0.5升水煮沸后,将储水箱排出蒸煮装置。用过的油靠重力流到排水箱中。分别考虑0.5、2.1、2.8和6.5 g/s的流量。充电效率为51.3%,总放电效率范围为15.3 ~ 34.7%。当电源嵌入储罐内时,充电效率提高。在不同的流量下,瞬时放电功率都有一个峰值。所采用的蒸煮装置传热效率范围为34.7 ~ 57.6%。根据所获得的排放结果,提出并说明了一种油基TES系统的施胶方法。关键词:三缸,施胶,出料,效率,热能

Performance Investigations of the Charging and Discharging Processes in a 3-Tank Thermal Energy Storage System
The paper presents a 3 tank thermal energy storage system. The system consists of cold oil reservoir, heat storage tank, and a residual drainage tank. Cold oil flows by gravity into a heating chamber and after being heated to the required temperature, a mechanical thermostat opens allowing the hot oil to flow into a heat storage tank. The storage tank was discharged through the cooking unit by boiling 0.5 litres of water. The used oil flowed by gravity to the drainage tank. The discharge flow rates of 0.5, 2.1, 2.8 and 6.5 g/s were considered. A charging efficiency of 51.3% and overall discharging efficiency range of 15.3 34.7% were achieved. Charging efficiency increased when the source was embedded in the storage tank. The instantaneous discharge power had a peak value for each flow rate. The adopted cooking unit had a thermal transfer efficiency range of 34.7 57.6%. A method for sizing oil based TES systems was proposed and illustrated based on the obtained discharge results. Keywords:     3-tank, sizing, discharging, efficiency, thermal energy
