Embodiment 1

[0040] Apply the inventive method to a building with energy consumption of 25-30W / m 2 In the building of , the first adjustment cycle that has already occurred is 0:00-5:59, and 0:00 in the first adjustment cycle is the adjustment time of the first adjustment cycle, and the upcoming second adjustment cycle time is 6:00-11:59. The average value of the outdoor measured value in the first adjustment period is 15 degrees, and according to the recorded temperature value of the weather forecast, the average value of the outdoor temperature forecast value of the second adjustment period is calculated to be 11 degrees, 15-11=4 degrees, It is greater than 3 degrees, so the adjustment condition a in step S1 is met. Therefore, at 6:00, which is 6 hours from the first adjustment period, the thermal station starts to adjust the temperature of the heat medium. At this time, the actual room temperature is 19 degrees, and the target room temperature is 18 degrees. The actual room temperature...

Abstract

The invention relates to a heating medium temperature regulation and control method of a heating station. The heating medium temperature regulation and control method comprises the following steps of S1, periodically evaluating whether heating medium regulation and control are needed or not, wherein an evaluating method is that whether an adjustment condition is met or not is evaluated based on the difference value of outdoor temperature average values of two adjacent evaluation periods and the difference value of the target room temperature and the actual room temperature, and if the adjustment condition is met, heat medium regulation and control are needed; S2, if the adjustment condition is met, the heating station starts to adjust the temperature of a heating medium, and first adjustment is carried out according to a certain adjustment amplitude; S3, after a certain time interval T', whether second adjustment is needed or not is judged; and S4, when the second adjustment is needed, the second adjustment is carried out according to a certain amplitude, and the amplitude of the second adjustment is smaller than that of the first adjustment. According to the heating medium temperature regulation and control method, on-demand heat supply and accurate heat supply are realized.

Description

technical field [0001] The invention relates to the technical field of heat network management, in particular to a method for regulating the temperature of a heat medium in a heat station. Background technique [0002] According to the heat supply form, the heat power station is divided into direct supply station and indirect supply station. The former is directly supplied by the power plant to the user, and the temperature is high, difficult to control, and wastes heat energy. It is the product of the initial power plant waste heat welfare heating. Later, when fees were charged, there were heating companies. With the development of the commodity economy and the commercialization of heat, heat companies began to improve the quality of heat supply, and only then did they have direct supply stations, which belonged to centralized heat supply. There is also a boiler for heating, which saves the power plant link, but the efficiency is low and the pollution is large, and it is ...
