Description
The technical field is as follows:
the invention relates to the field of heating and ventilation equipment, in particular to a heating and ventilation big data energy-saving system.
Background art:
modern society is facing more and more serious energy crisis, and building energy conservation has received more and more attention. Central air conditioning is an indispensable energy consumption operation system in modern buildings. The central air-conditioning system consumes a large amount of energy while providing comfortable living and working environments for people. According to statistics of relevant data, the energy consumption of buildings in China accounts for about 30% of the total energy consumption, and in buildings with central air conditioners, the central air conditioner accounts for about 70% and tends to increase year by year. At present, most air conditioning systems using water-air are adopted in buildings in China.
On the premise of meeting the requirement of comfort level, the reasonable control of the operation of the central air-conditioning system is the most effective measure for reducing the energy consumption of the air conditioner. At present, a variable flow control technology based on constant temperature difference or constant pressure difference is adopted for the operation energy conservation of a cold source of the central air conditioner, and compared with the traditional constant flow operation mode of the central air conditioner, the application of the variable flow control mode reduces the operation energy consumption of a chilled water pump of the central air conditioner, and the variable flow control technology is widely applied. However, the effect of practical application shows that the current variable flow control mode has obvious defects in the aspects of ensuring user comfort, energy saving effect and the like, and because of the difficulty in acquiring the information of the terminal equipment and the user, the centralized effect of the user load is still used as the control basis, the actual condition of user load change cannot be well reflected and the comfort of all users can not be ensured. The control mode has the defects that the further reduction of the operation energy consumption of the central air-conditioning system is restricted.
The current central air-conditioning system does not have the function of real-time adjustment according to the requirements of users, namely, the requirements of the users are not known, the load requirement of each time period is not known, and accurate control cannot be achieved. The cold and heat quantity of the host equipment of the existing central air-conditioning system is mainly adjusted according to the change of the return water temperature. Under the cold supply working condition, the temperature difference between the water supply and the water return of the water system is less than 3 ℃ (the design temperature difference is 5 ℃), and under the heat supply working condition, the temperature difference between the water supply and the water return of the water system is less than 6 ℃ (the design temperature difference is 10 ℃), and measures for reducing the flow are adopted to adjust the cold and heat loads. However, the flow of the main engine of the system is fixed, and even if a variable-frequency circulating water pump is adopted, the system works in a full-frequency full-load state, and the due flow regulation effect cannot be achieved.
The central air-conditioning system is provided with cold and hot loads by the main machine, and the pipeline constant flow system is used for providing cold and hot water for the end equipment. All the tail end equipment is manually controlled, when the equipment is started, the electric two-way valve of the tail end pipeline is opened, and circulating water of the main pipeline flows through the tail end equipment through the two-way valve to perform cold and heat exchange. When the indoor temperature reaches the set temperature, the electric two-way valve is closed, and the tail end waterway circulation is blocked. The system operates regardless of the number of end devices that are turned on and regardless of whether the end device temperature is satisfied. Once the system is started to operate, the host equipment and the circulating water pump run at full load, and rated water flow and cold and hot loads are provided for the tail end. The host system equipment and the tail end independent equipment operate independently respectively, and the load demand change of a single user cannot be reflected well and the comfort level cannot be guaranteed only by taking the centralized effect of the user load as a control basis.
Once the installation of the existing central air conditioning system is completed, the system is independent. The cold and hot load adjustment device cannot be fully combined with the change of weather and the actual temperature requirement, and can only receive the adjustment of cold and hot loads in a passive mode through the feeling of a user, and the mode is passive and slow, so that the requirement of comfort level is lowered. It is impossible to help people to arrange time effectively and save various energy sources.
The invention content is as follows:
the invention aims to provide a heating and ventilation big data energy-saving system, which is based on the basic defects of the existing central air-conditioning energy-saving control mode and the knowledge on the development of a network control technology, does not adopt a control mode based on the centralized effect of user load any more, but fully utilizes the advantages of the network control technology, directly takes the information of a central air-conditioning terminal user as the basis and aims at researching 'adjustment according to user load requirements', and adopts an improved dynamic coefficient value to predict the load requirements of users in the next time period in real time according to the current load of the terminal users on the basis of a central air-conditioning system terminal equipment cold consumption model provided by the invention. On the basis of the real-time prediction of the dynamic load of the air conditioner, the variable flow control of the central air conditioning system is completed by combining weather parameters, a new control mode is provided for the variable flow control of the central air conditioning system, the purpose of adjusting the load of a central air conditioning host according to the load requirement of a user is achieved, and the running energy consumption of the central air conditioner is effectively reduced.
