摘　　要：本文通过负荷计算分析,发现某办公建筑负荷率在90%~100%区间的占整个空调运行期的时间比例不足2%。运用MATLAB仿真模拟并分析了空调期采用定压差变频变供水温度运行策略的运行情况,得到能耗、流量、供回水温度等的变化曲线,并与定压差流量旁通方法进行对比,发现采用变频变流量可较流量旁通方式节能7%。By building load calculation and analysis, it was found that an office building load rate of 90% to 100% accounts for less than 2% of the entire air conditioning operation time. By using MATLAB simulation and analysis of the operation of air-conditioning system with the optimization control of constant pressure difference value, variable frequency and variable water temperature, it can be access to the change curve of energy consumption, water flow, return water temperature and so on. Compared with the result constant pressure difference value and flow bypass strategy, it is found that variable frequency variable flow can save energy by 7%.
