Embodiment Construction
[0055] The invention proposes a secondary network water supply temperature setting method based on weather forecast and system historical data. The method uses weather forecast data, user room temperature data, and historical supply and return water temperature and flow data of the heating system to calculate the next time system set water temperature.
[0056] For the central heating secondary network, this scheme proposes a method to calculate the set water supply temperature of the secondary network based on the current meteorological data, user room temperature data, and historical supply and return water temperature and flow data of the heating system. The method relies on the room temperature sensor installed in the heat user's room, the secondary side supply and return water temperature sensor of the heat exchanger, the flow sensor and reading the hourly weather forecast to implement. The room temperature sensor can collect the user's indoor temperature in real time, an...

The present invention relates to the field of centralized heating operation adjustment. In order to propose a simple and feasible method for setting the water supply temperature of the secondary network based on weather forecast and system historical data, which facilitates the efficient operation of the system and improves the satisfaction of users with heat, the present invention is based on The method for setting the water supply temperature of the secondary network based on historical data and meteorological parameters is implemented by relying on the room temperature sensor installed in the thermal user's room, the temperature sensor of the secondary side of the heat exchanger, the flow sensor, and the reading of the hourly weather forecast. The sensor collects the user's indoor temperature in real time. The primary and secondary side supply and return water temperature and flow rate sensors of the heat exchanger respectively collect the primary and secondary side supply and return water temperature and flow rate of the heat exchanger in real time, and transmit them to the host computer and save them in the database. Read the data in the database to obtain the set value of the water supply temperature of the secondary network, and the controller adjusts the electric valve according to the difference between the current water supply temperature of the secondary side and the set temperature. The invention is mainly applied to the occasion of centralized heat supply management.
Description
technical field [0001] The invention relates to the field of central heating operation adjustment, in particular to a method for setting the water supply temperature of a secondary network based on historical data and meteorological parameters. Background technique [0002] The water supply temperature of the heating system directly affects the thermal comfort of end users and the energy consumption of the system. At present, the commonly used methods for setting the water supply temperature of heating systems include empirical methods, machine learning prediction methods, and theoretical calculation methods. [0003] The empirical method to set the water supply temperature mainly depends on the experience of the on-site staff, and adjusts it according to the current meteorological parameters and user feedback. Therefore, the adjustment effect of the experience adjustment method largely depends on the experience of the operator. Due to the dynamic characteristics of the he...
