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 The widespread use of large central air conditioning has brought a new problem: the accurate measurement of energy consumption by users, the cost of sharing is reasonable and so on, which directly affects the level of modern property management, so cold and heat measurement technology is imminent. In this paper, through the theoretical analysis of the relevant data that affect the measurement of the hot and cold water table of the central air conditioning system, the mathematical model is established, the measurement scheme is determined, the problems existing in the measurement are solved, and the prototype work of the hot and cold table is completed. Through the test data, repeated software and hardware parts of the instrument. The current measurement accuracy of the instrument has been greatly improved than the prototype. After several users indicate that the instrument is a high performance practical measurement device
