Application test of the onoff valve regulation and heat allocation technique based on building heat metering

In order to verify the adaptability of the onoff control strategy and the rationality of the heat allocation mode based on accumulative open times of onoff valves combined with heating areas, tests an actual heating system by applying the technique. The result shows that the temperature deviation between the set and actual value of rooms under different loads, positions and orientations is minor and the heat allocation mode based on accumulative open times of onoff valves combined with heating areas is reasonable.
