摘要
以某商业项目空调水系统冷水及冷却水双侧大温差结合二次泵变频技术的应用为例,从末端设备、水泵、冷却塔、主机、管路等方面分析了空调系统设计流程和设备选择过程。比较了大温差系统和常规温差系统的耗电功率和初投资,验证了大温差技术在该项目应用中的可行性。
Taking the large temperature difference water system with variable secondary pumps as an example, in which to the both sides of chilled water and cooling water is applied the large temperature difference technique, presents the HVAC system design procedure and selection of equipment such as the terminal equipments, pumps, cooling towers, chillers and pipelines. Compares the system to the conventional system in power consumption and initial costs, and validates the feasibility of this technique in this project.
