According to the annual comprehensive energy efficiency analysis of air conditioning water system,presents a calculation method of the pump operating condition point at different load ratios, including the method to determine the pipeline impedance and the influencial factors of the pump operating condition point.Taking a project as an example,analyses the operating state and seasonal energy consumption of each pump,under the following conditions:the system consists of three large capacity heat pump units and a small capacity heat pump unit with the pumps running at constant frequency,the load ratio is from 10% to 100%,and with two strategies of “priority of small capacity pump”and “priority of large capacity pump”.Many factors affect the energy consumption of air conditioning water system.Based on the operating characteristics,the reasonable matching pump model and optimization of operating strategy are important to improve the stability and reduce the energy consumption of air conditioning system.
