Research on optimization design methods of air conditioning systems in a large hospital in Shaanxi Province

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.
