Embodiment Construction

[0048] The heat user of the present embodiment has three rooms, and the model of the radiator of the first room is column type M-132, and the number of assembling pieces is 10; Its characteristic coefficient, for 10 models, is the constant of column type M-132 is :K M1 =5.8224, n 1 =1.286; the connection form is up and down on the same side, and the installation form is installed on the wall with a cover plate. The distance between the cover plate and the top of the radiator is 40mm, so: the first radiator assembly number correction factor β 11 =1.0, the first radiator connection form correction coefficient β 12 =1.0, the first radiator installation form correction coefficient β 13 =1.05.

[0049] The model of the radiator in the second room is column type M-132, and the number of assembled pieces is 8 pieces. Its characteristic coefficient, for 8 pieces, the constant of column type M-132 is: K M2 =4.6579, n 2 =1.286; Correction factor β for the number of assembled pieces...

Abstract

The invention discloses a household heat distribution meter using a three temperature sensor as a measuring unit. The household heat distribution meter using the three temperature sensor as the measuring unit comprises a single chip microcomputer and a display. Each household radiator is provided with an inflow-outflow temperature sensor and an indoor temperature sensor. Formulas used for calculating logarithmic mean temperature difference and heat dissipating capacity of the radiator are stored in the single chip microcomputer. Relevant parameters used for calculating the heat dissipating capacity of each radiator are stored in the single chip microcomputer in advance. The single chip microcomputer conducts the following steps every theta times: (1) reading the inflow-outflow temperature and the indoor temperature of a first radiator; (2) calculating the logarithmic mean temperature difference; (3) putting the logarithmic mean temperature difference and other parameters of the first radiator into the formula used for calculating the heat dissipating capacity to determine the heat dissipating capacity of the first radiator at time theta; (4) storing the determined heat dissipating capacity into an accumulator Q; and then using the same steps to calculate the heat dissipating capacity of a second radiator and until the heat dissipating capacity at time theta of the last radiator is stored in the calculator Q, when the heating period expires, numerical value of the calculator Q is the heat consumption amount of the household.

Description

Technical field [0001] The invention relates to a heating heat distribution meter, in particular to a household heat distribution meter with three temperature sensors as measuring units. Background technique [0002] The inventor of this patent has applied for an invention patent "three-temperature sensor heat distributor", patent number ZL200710071963.0. The heat metering formula of the distributor is theoretically derived from the heat metering formula of the heat meter. The heat metering of the heat meter is the most rigorous in theory. The heat metering of the heat distributor is the actual heat dissipation of the radiator. The traditional electronic heat distribution meter measures not the actual heat dissipation of the radiator but the share of the total heat consumption. [0003] However, one heat distributor with three temperature sensors must be installed for each radiator, which will cause the management personnel of the thermal formula to read the meter more ofte...
