Abstract

The invention provides a heat exchange station feedback prediction regulation and control method based on indoor temperature. The method aims to solve the problems of high energy consumption and low heat comfort caused by an existing heat exchange station feedforward regulation method, and mainly comprises the following steps: establishing a secondary water supply temperature prediction model; determining water supply and return temperature difference change values at different outdoor temperatures; determining an adjustment period and time; and determining a secondary water supply temperaturecorrection model. Compared with a traditional adjusting method, the method can guarantee the operation stability of a pipe network, improve the heat comfort of heat users and achieve energy-saving operation of a heat supply system.

Description

technical field [0001] The invention belongs to the technical field of heat supply and energy saving, and in particular relates to a feedback prediction control method for a heat exchange station based on indoor temperature. Background technique [0002] The ultimate goal of heating is to reach the standard indoor temperature. Only when the room temperature meets the user's thermal needs can it be called truly realizing on-demand heating. With the rapid development of intelligence, most of the heating stations in China have realized remote monitoring and remote control of heating parameters. At that time, the personnel of the heating company can check the heating parameters of the entire heating system anytime and anywhere, and make timely energy-saving control strategies , which means that the high energy consumption caused by backward infrastructure has gradually weakened. However, the problems of poor thermal comfort and high energy consumption still exist. The main rea...
