Embodiment 1

[0034] Such as figure 1 with image 3 , the installation principles and calculation methods of typical room temperature monitoring points in buildings without basements;

[0035] (1) Divide all households in the building into three categories, the first category includes the top floor households, the second category includes the middle households, and the third category includes the left, right and bottom households;

[0036] (2) The first type of households should install at least one room temperature monitoring point, the second type of households should install at least two room temperature monitoring points, one monitoring point has heating for the upstairs residents, and the other upstairs residents have no heating, and the third type of residents should install at least two At room temperature monitoring points, one monitoring point provides heating for upstairs residents, while the other upstairs does not provide heating. A total of at least 5 monitoring points should ...

Embodiment 2

[0042] Such as figure 2 with image 3 , there are installation principles and calculation methods for typical room temperature monitoring points in basement buildings:

[0043] (1) Divide the building households into four categories, the first category includes the top floor households, the second category includes the middle households, the third category includes the left and right edge households, and the fourth category includes the bottom floor households;

[0044] (2) The first type of households should install at least one room temperature monitoring point, the second type of households should install at least two room temperature monitoring points, one monitoring point has heating for the upstairs residents, and the other upstairs residents have no heating; the third type of residents should install at least two One room temperature monitoring point, the upstairs residents of one monitoring point have heating, and the other upstairs residents have no heating; the fou...

Embodiment 3

[0050] A heat exchange station serves residential buildings with high floors. In order to ensure the safe and stable operation of the system, it is divided into high and low areas. Among them, floors 13 and above are high areas, and floors below are low areas. There is no basement. Indoor temperature measuring points are randomly installed in each district. The communication signal of the temperature measuring points in the high area is not good, which leads to the low efficiency of room temperature point collection. A total of 6 room temperature monitoring points are online normally, and 27 points in the low area are normally online.

[0051] In December, the supply and return water temperatures in the high and low areas are basically equal. According to experience, it can be considered that the heating effects in the high and low areas are basically equal, that is, there is not much difference in the comprehensive room temperature. See Table 1 for the average room temperatur...

Abstract

The invention provides a comprehensive indoor temperature calculation method based on building user classification, and aims at overcoming the defects of an existing building typical room temperaturemonitoring point random installation and average value calculation method. The comprehensive indoor temperature calculation method mainly comprises the steps of determining the type of a target building, classifying users at different positions of the building, installing room temperature monitoring points at the typical positions of all the categories, determining the weights of all the typical points, and finally calculating the comprehensive indoor temperature capable of reflecting the heat supply effect of the building. Therefore, a heat supply system is guided to operate in an energy-saving manner, and real on-demand heat supply is achieved.

Description

technical field [0001] The invention belongs to the technical field of heat supply and energy saving, and in particular relates to a comprehensive indoor temperature calculation method based on building user classification. Background technique [0002] Only when the heating system realizes on-demand heating can it improve energy utilization efficiency, reduce heating energy consumption, and alleviate air pollution during the heating season in heating cities. The only criterion for judging whether the system is on-demand heating is whether the indoor temperature reaches the standard. Only when the indoor temperature reaches the target value can it be called real on-demand heating. However, it is impossible to install room temperature monitoring equipment for every household. Therefore, heating companies often install room temperature in typical households in buildings far, middle and near from the heat exchange station. However, there are many heat users in each building. Wh...
