Embodiment Construction

[0036] The following drawings are used to illustrate the present invention, but not to limit the scope of the present invention.

[0037] figure 1 It is the control flow chart of the compensation algorithm of the present invention. As shown in the figure, the calculation formula of water supply temperature is selected according to the outdoor temperature. According to the height of the outdoor temperature, the outdoor temperature is divided into t<-8°C, -8°C≤t<0°C, 0 ℃ ≤ t < 8 ℃ and t ≥ 8 ℃, there are four sections in total. Different temperature sections correspond to different calculation formulas (formula 1~4). Substitute the collected temperature and set temperature values ​​into the above formula to obtain the water supply temperature value, and at the same time The calculated water supply temperature is corrected according to different time periods, weather and holidays. The corrected temperature is the target water supply temperature. The opening of the electric three-w...

Abstract

The invention relates to a climate compensation algorithm and a control method for supply water temperature of a central heating system. The climate compensation algorithm comprises calculation formulas of different outdoor temperature ranges, water temperature corrections of different time ranges, water temperature corrections of different weathers (sunny days and snow days) and water temperature corrections during holidays. A control method of a climate compensator electric three-way valve comprises the steps of: calculating a theoretical user supply water temperature value according to an outdoor temperature and changes of a user supply water temperature, correcting the theoretical value to be a target supply water temperature value, comparing an actual user supply water temperature with the target supply water temperature, and adjusting the electric three-way valve to a best working state through combining with a heating end user indoor temperature and using an intelligent proportion integration differentiation (PID) control method, so that the actual supply water temperature output by a heat source accords with the target supply water temperature value, and the actual supply water temperature is tightly combined with the outdoor temperature, and consequently, heat supply requirements of heat users of the heating system are ensured, and the aim of maximum energy saving operation is achieved.

Description

technical field [0001] The invention relates to a climate compensation algorithm and control method for a centralized heating system, in particular to a system that can automatically control the heating system according to the change of outdoor meteorological parameters and the heat consumption law of heating users, according to a specific compensation algorithm and control method Quality adjustment and volume adjustment to meet the heat demand of heating users whose indoor temperature reaches the standard. The invention is suitable for regional central heating climate compensation system. Background technique [0002] At present, the control of the heating system is relatively simple, even manually controlled, and the management is relatively extensive, which will cause the end heating users to be underheated or overheated, and affect the thermal comfort of the heating users. In fact, the user's demand for heat is constantly changing due to factors such as outdoor temperatu...
