Dynamic climate compensation method for centralized heating

Abstract

The invention discloses a dynamic climate compensation method for centralized heating. Firstly, the outdoor temperature is predicted, water supply and return temperatures are adjusted some time ahead according to the predicted value of the outdoor temperature, and the hysteresis of pipe network adjustment in the manner that adjustment is performed while sampling is overcome. The outdoor temperature of the next day is predicted according to local historical meteorological data and weather forecast of the meteorological department, and the value is used as basic data for prediction of a thermal load; and then the thermal load is predicted, that is, the thermal load curve of the next day is calculated according to the outdoor temperature. With the method, the outdoor temperature is reasonably predicted so as to realize advanced dynamic adjustment of a climate compensator; heating medium parameters of a heating system are adjusted by the aid of an adjusting model according to the thermal load value set in advance, a heat source is changed from original wide passive heating into active heating, on the premise that the indoor temperature for the user is stable, the operation adjusting indictor of the heating system within the specified time are given in advance, the heating efficiency is improved, and the heating energy consumption is reduced.

Description

technical field [0001] The invention relates to a dynamic climate compensation method for central heating. Background technique [0002] The purpose of the heating system to heat the heating building is to meet the needs of users for thermal comfort and to ensure that the indoor temperature is within a certain range. With the change of outdoor temperature, the user's indoor temperature is prevented from being too low or too high. , while the system is running, due to changes in outdoor meteorological conditions and other factors, the heat load of the building will change accordingly. Therefore, in order to adapt the heat supply of the heat source to the change of the user's heat load, it is necessary to adjust the heat supply of the heat source accordingly, that is, the heating system should adjust the heat supply according to the change of the building's heat load. In order to realize on-demand heating, so as to ensure that the user's indoor temperature meets the thermal c...

AI Technical Summary

Problems solved by technology

In the adjustment and control process, because the outdoor temperature is collected and adjusted immediately, and because the heating pipe network is a relatively large system, there is a user-side hysteresis in the pipe network adjustment, resulting in distortion of the adjustment

It is impossible to predict the 24h outdoor temperature change in advance, resulting in passive heating at the heat source, which not only increases the heating cost, but also cannot reflect the dynamic characteristics of the building's heat load, and cannot well meet the user's heat demand
