摘要

针对一种自制的能够与太阳能空调系统匹配的相变蓄冷材料，建立了蓄冷球蓄\释冷过程数学模型，得到稳态及非稳态工况下蓄冷球内温度分布、蓄\释冷量、蓄\释冷速率的变化规律及影响因素。同时，在相应工况下对单个蓄冷球进行蓄\释冷循环实验，验证理论结果。研究表明，自制蓄冷球能够在170min完成相变。缩小球径、降低冷冻水温度、增大球壁热导率及减小球壁厚度均可缩短蓄冷时间。稳态运行工况下，蓄冷球的蓄\释冷量分别为17.30kJ和16.46kJ；太阳能空调非稳态运行工况下，蓄冷球在165min完成相变，蓄冷量为16.34kJ。

Abstract

A phase change material (PCM) is prepared for cold storage application of solar air-conditioning systems. On the basis of the self-developed PCM

the mathematical model of a spherical capsule storage ball is built to analyze the variation and influencing factors of the temperature distribution

cold storage capacity and cold storage rate during the charging and discharging process. Experiments on the charging and discharging characteristics of the storage ball are conducted in certain working conditions. The results show that the phase transition of the storage ball completes in 170min. The charging duration can be reduced by decreasing the chilled water temperature

sphere diameter and thickness of the sphere wall

and increasing the thermal conductivity of the sphere wall. In a steady state condition

the charging and discharging capacity are 17.30kJ and 16.46kJ

respectively. In a non-steady state condition

the phase transition completes in 165min with a charging capacity of 16.34kJ.
