specific Embodiment approach 1

[0052] Specific implementation mode one: the thermal metering temperature apportionment method with window opening correction function of the present embodiment, it is realized according to the following steps:

[0053] Step 1. Calculate the heat supply Q shared by each household i Divided into two parts: one part measures the heat Q at room temperature ti , and the other part is the additional heat Q for opening the window wi The measured heat at room temperature is apportioned according to the average indoor temperature measured by the metering temperature sensor, and the additional heat for opening the window is calculated according to the average temperature near the window measured by the monitoring temperature sensor, that is

[0054] Q i =Q ti +Q wi (1)

[0055] The heat supply apportioned and metered by each household within a unit time in the building is: ΔQ ik =ΔQ tik +ΔQ wik ;

[0056] Step 2. Calculation of the measured heat ΔQ at room temperature of e...

Abstract

The invention discloses a thermal metering temperature apportionment method with a window opening correction function, which relates to a thermal metering temperature apportionment method. The invention solves the problems that the existing temperature-based heat apportionment system cannot recognize the windows in real time and the identification time lags, cannot quantitatively measure the heat consumed by opening the windows, and cannot quantify the penalty mechanism for opening the windows. The main steps of the method of the present invention are: the heat supply of each household in the unit time of the building is: ΔQik=ΔQtik+ΔQwik, the heat measured at room temperature of each household within the calculation unit time ΔQtik, and the additional heat of each household opening windows within the calculation unit time ΔQwik, find out the heat supply apportioned and metered by each household. The invention theoretically solves the problem of quantitative calculation of energy consumption caused by opening windows, and provides theoretical support for the temperature apportionment technology. The problem of real-time identification of window opening in the temperature and heat allocation method is realized. The invention can quantitatively measure the heat consumed by opening the window, quantify the penalty mechanism for opening the window, and solve the problem of justice.

Description

technical field [0001] The invention relates to a heat metering temperature apportionment method. Background technique [0002] The heating area in our country consumes a large amount of energy for heating every year. In order to reduce heating energy consumption, the state has been vigorously promoting the reform of the heating charging system, and implementing charging according to heat. If heating is to be charged according to heat, it is necessary to have a heat meter that can measure heat. Enterprises at home and abroad are all focusing on China's huge heat metering market, and have invested funds in the development of heat metering instruments and invested in developing the heat metering market. In just a few years, there are more than 200 manufacturers of household heat meters alone. At present, the technical route adopted by many domestic enterprises and inventors mostly uses the method of measuring the heat supplied by the heating network to each household in the...
