Three-temperature sensor heat distributor

Abstract

The invention discloses a heating heat metering tri-temperature sensor thermal distributor, including a single chip computer, an influent temperature sensor, a backwater temperature sensor, an indoor temperature sensor and a display, wherein the tri-temperature sensor and the display are respectively connected with the I / O port of the single chip computer storing three formulas: 1.computing the radiator characteristic coefficient A, 2.computing the logarithm average difference in temperature, 3.computing the radiating quantity of the radiator. The tri-temperature sensor thermal distributor is input with the related parameters of the radiating quantity of the radiator and the interval time into the single chip computer before the installation; the program executes the following steps when computing: reading the temperature of the temperature sensor in fixed interval, computing the logarithm average difference in temperature according to the three read temperature by the formula 2, then obtaining the radiating quantity of the radiator using the logarithm average difference in temperature and storing into the accumulator of the single chip computer. The invention is suitable for the heating heat metering of the buildings, such as the house, the enterprise and institution and the business building.

Description

Technical field [0001] The invention relates to a heat distributor for heating, in particular to a heat distributor with three temperature sensors. Background technique [0002] At present, the electronic heat distributors used for heating heat metering at home and abroad are generally divided into two categories, one is a single temperature sensor heat distributor, and the other is a dual temperature sensor heat distributor. The temperature at a certain point is used as the average surface temperature to calculate the heat dissipation, and the latter measures the heat dissipation of the radiator based on the temperature difference between the average surface temperature of the radiator and the room temperature. Its disadvantages are: [0003] 1. This measurement method based only on the temperature of one point on the radiator or the temperature of the radiator and the room temperature lacks theoretical basis; [0004] 2. Due to the uncertainty of the average temperature ...

AI Technical Summary

Problems solved by technology

[0003] 1. This measurement method based only on the temperature of one point on the radiator or the temperature of the radiator and the room temperature lacks theoretical basis;

[0004] 2. Due to the uncertainty of the average temperature measurement of the radiator, it is inaccurate to measure the average temperature by fixing the heat distributor at one point;

[0005] 3. There are too many correction coefficients and the correction process is too complicated;

[0006] 4. Due to the above-mentioned reasons, the reading of the heat distributor does not reflect the actual heat consumption, so there is a phenomenon that the same reading this year is different from last year, but the heat fee delivered is different, causing confusion in charging
