Abstract：
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.
