随着电力需要量的增加,电力负荷在昼夜间的差别出现逐年扩大的倾向.作为城市用电平衡化的措施,开发有效的蓄热式空调系统,对电力公司和用户双方都带来经济利益,这已成为最近的重要的技术课题.本文介绍了为中小型建筑物而开发的组合式冰蓄热的空调系统.该空调系统以风冷热泵式冷却装置为基础,利用直接膨胀方式的制冰循环,构成不用辅机动力的紧凑的系统.样机试验时,制冰率实现了37%(体积比),蓄热槽的体积是老式水蓄热式的1/5.
As the demand for electricity increases, the day-night differences in electricity load tend to increase year by year.As a measure of urban electricity balance, developing an efficient regenerative air-conditioning system will bring economic benefits to both power companies and users , Which has recently become an important technical issue.This paper presents a combined ice-storage air-conditioning system developed for small and medium-sized buildings.The air-conditioning system is based on an air-cooled heat pump cooling system and utilizes a direct expansion Ice cycle, the formation of compact system without auxiliary power.Pilot prototype test, the ice rate achieved 37% (volume ratio), heat storage tank volume is the old water-regenerative 1/5.
