Intelligent buildings are the application of the Internet of Things in buildings, and building automatic control systems can bring people a safe, efficient, comfortable and convenient building environment. Building automation systems can improve the performance of equipment in buildings and give full play to the advantages of the Internet of Things to achieve optimal energy dispatch and reduce costs. It is the most in-depth and potential energy-saving technology in intelligence. The intelligence of buildings is now directly linked to the management level of the property.
The most common electrical appliance used in summer is the air conditioner. However, the air conditioner is also a bigger appliance. On the one hand, the air conditioner consumes a lot of energy, which will undoubtedly increase the cost of building management; Even, forgetting to turn off the air conditioner, etc. are the main causes of waste.
Energy-saving operation plan for optimizing cold source supply scheduling
In response to the above problems, an optimized control mode is adopted, based on the principle of “time sharing, segmentation, and temperature sharing”, and the cooling source is allocated according to the actual usage. According to the different time of the building’s demand for the cooling source, the building automation system is used to return the fan The water valve control is divided into different time periods to meet their needs. For example, during the period from 9:00 to 11:00 in the morning, the system will give priority to the sunny part, and the same is true in the afternoon. In other periods, according to specific usage conditions, when the return water temperature is too high and the cold source is insufficient, the secondary demand can be increased.
From the actual situation, through real-time control of the start and stop time of the air conditioning equipment, fan frequency, fresh air valve opening and water valve opening, the effect of optimizing the distribution of cold sources is achieved. Without turning on other units and pumps, The optimized supply of cold sources is realized, and the waste of cold sources caused by increasing the number of equipment operations due to insufficient cold source demand is avoided.
After the building is put into operation, it is a comprehensive and systematic control process to accurately adjust the operating state of the equipment according to the actual use of the building and the equipment load, and to achieve energy-saving operation while ensuring indoor comfort. Property personnel need to fully understand the characteristics of energy demand in the building, be proficient in the operating principles of the building automation system and controlled equipment, and target the overall energy deployment, deploy the energy supply to the maximum extent, achieve energy saving effects, and realize the coexistence of all parties’ interests .
