陕西省某大型医院空调系统优化设计方法研究
Research on optimization design methods of air conditioning systems in a large hospital in Shaanxi Province
摘要：
大型医院总耗电量中,空调系统耗电量达40%以上,为响应国家“双碳”战略目标、降低医院运行能耗,减少空调系统耗电量首当其冲,但在工程实践中,高投资往往制约了低碳、高效空调系统的发展前景。基于陕西省某大型医院空调系统优化设计,从温湿度独立控制系统、大温差+高温冷水系统、干式风机盘管系统3个设计要点出发,对空调系统碳排放、运行能耗与初投资并行降低的优化设计方法进行了探讨,以应对高效空调系统投资高的问题,助推高效空调系统技术的发展与应用。
Abstract：
In large hospitals, the electricity consumption of air conditioning systems accounts for over 40% of the total electricity consumption. In response to the national “dual carbon” strategic goals and reducing the energy consumption of hospitals, reducing the electricity consumption of air conditioning systems is the top priority. However, in engineering practice, high investment often restricts the development prospects of low-carbon, high-efficiency air conditioning systems. Based on the optimization design of the air conditioning system of a large hospital in Shaanxi Province, this study discusses an optimization design method aiming to concurrently reduce carbon emissions, operational energy consumption, and initial investment of the air conditioning system, focusing on three design points: the temperature and humidity independent control system, the large temperature difference and high-temperature chilled water system, and the dry fan coil system. This approach addresses the issue of high investment in high-efficiency air conditioning systems and promotes the development and application of high-efficiency air conditioning system technologies.
