冷热量测试技术研究

摘要

The popularization of large-scale central air-conditioning system (CACS) has brought forward a new problem,i. e. how to measure the cooling and heating quantum accurately. This problem will directly affect the quality of modern property management. So the study on the technology of measuring heat and cool is very necessary.In this paper, the detailed thermal analysis and the mathematical model of relative parameters that affect the measurement of heat and cool are discussed. A sample instrument based on the model is made, After the trial-use by several customers, the device is proved to be practical,worthwhile and of good capacity.%大型中央空调的普遍使用带来了一个新的问题:各用户消耗能量的准确测量、费用的分摊是否合理等,直接影响到现代物业管理的水平,因此冷热量测量技术的研究迫在眉睫.本文通过理论分析影响中央空调系统冷热表测量的相关数据,建立了数学模型,确定了测量方案,解决了测量中存在的问题,并完成了冷热表的样机制作工作.通过试验数据,反复修正仪表的软件和硬件部分.目前该仪表的测量精度较原理样机有较大的提高.经若干用户使用表明,该仪表是具有较高性能的实用测量装置.
