A method for apartment registration of consumed heat in a high-rise building with vertical run of tubes (standpipes) consists in that from the beginning of measurement in each fixed time for the central computer are formed: with the first integral temperature sensor - integral temperature of heat carrier values at entrance to the room for the whole time of measurement, with the second integral temperature sensor - integral value of temperature of heat carrier at exit from the room for the whole time of measurement, and the central computer having obtained data from the flow rate meter of volumetric flow rate of heat carrier performs calculation of the average value of volumetric flow rate of heat carrier through the room standpipe during the whole time of measurement, with calculation of the room consumed heat by the formula:(2)where- average value of volumetric flow rate of heat carrier through the room standpipe during the whole time of measurement, m/h;- thermal coefficient, GJ/C°;- temperature of heat carrier at entrance to the room, C°;- temperature of heat carrier at exit from the room, C°;- same for all the measurements time of beginning of measurement, h;- fixed value of time for formation of measured values, h;- time of measurement, h, where- number of measurements, 1, 2, 3 …;- the whole time of measurement, t;- integral value of temperature of heat carrier at entrance to the room during the whole time of measurement;- integral value of temperature of heat carrier at exit from the room during the whole time of measurement, and in the sum of calculations by the rooms it forms the value of apartment consumed heat. |
