| Description
| - The utility model relates to a digital integrated intelligent control system of a central air-conditioner, which has the key technology of building an intelligent working condition calculation control processing system to accurately calculate timely dynamic supplied water temperature. The intelligent working condition calculation control processing system consists of a fan coil working condition collection processing module group, an indoor supplied water temperature calibration module and a simulation calculation correction supplied water temperature module; an air-conditioner main machine is enabled to refrigerate according to dynamic actual requirements under the control of the intelligent working condition calculation control processing system, simultaneously the digital integrated intelligent control system can fit for economic operating condition performance curve of the air-conditioner main machine, reduce the consumption of the air-conditioner main machine and timely meet the requirements of indoor air-conditioning effect; and an operation marginal adjusting method of required cold capacity and efficiency built through the working condition signals and energy efficiency evaluation signals of the air-conditioner main machine can continuously adjust the energy efficiency of the air-conditioner main machine, and reduce running of the air-conditioner main machine under low working conditions, thereby correspondingly saving the consumed energy of the air-conditioner main machine.
