Abstract
The present invention relates to a method for measuring quantity of heat consumed by each home under identical temperature, which is used for measuring the quantity of heat consumed by each home in a subdistrict through a system device composed of an indoor constant temperature control circuit a, a system signal circuit b and a computer 8, and a corresponding application program, wherein the indoor constant temperature control circuit a is formed by the serial connection of a double-knife switch, a temperature control switch and an electromagnetic valve of each home; the system signal circuit b is composed of a relay, a plurality of switching-quantity input modules, a programmable controller and a heat measuring meter; the computer 8 finally reads heat measuring data. When the method is used for measurement, firstly, the temperature control switch of each home in the subdistrict is set under identical temperature; then, the system device of the present invention is used for recording the total quantity of the heat within prescribed time and the time of using the heat and not using the heat; because a heat supply area of each home in the subdistrict is known, a calculating formula (1) in the present invention can be used for calculating the quantity of the heat consumed by each home within the prescribed time. Consequently, the existing actual problem of measuring quantity of heat consumed by each home by one heat measuring meter is solved.
Description
Technical field
The present invention relates to the method for a kind of residential quarters Winter heat supply phase with the heat separating user metering, particularly a kind of in the method for setting under the identical prerequisite of each user's heat supply temperature with the heat separating user metering.
Background technology
Current, aspect the heat separating user metering, normally adopting heat supply to enter the method that a heat meter is installed at the water pipe place each user, though the method can be measured the actual heat of using of each resident family truly, there is the problem of the following aspects in actual applications in it.
(1) heat meter of current use can only measure in the indoor hear rate of resident family hot water, and can't measure hot water by the hear rate of supplying heat source (as the boiler room) in the piping system of resident family, thereby the interests of heat supply side are incurred loss.
(2) in a residential building, the resident family that has is positioned at the central part of buildings, the resident family that has is positioned at the position, outer of buildings, if they indoorly will reach same temperature in the heat supply phase, to consume more heat (because their indoor wall is by exterior wall of buildings) undoubtedly to the latter, and concerning the house purchaser of the almost same price house-purchase of flower, it is irrational that those resident families that are positioned at position, buildings outer all will pay more heating fee every year.
(3) when the heat meter of current use is installed by resident family, a manually-operated gate must be installed simultaneously, so that open and close according to actual needs or adjustment heating load.But we know with heat is easy of people's perception unlike water or electricity consumption, so people are when regulating the valve of heat supply water, can not accurately be transferred to optimum temperature once, this is in use invisible to have increased inconvenience of using, if regulate simultaneously excessive (it is too big that valve leaves) also can cause economically loss and the waste of the energy.
(4) use the mode of a heat meter metering with current each user with heat, can only measure when resident family opens heating valve, hot water is in indoor hear rate, if resident family's valve-off indoor temperature can reduce gradually, heat simultaneously in the man of resident family can be by body of wall from high to low to its indoor heat radiation, but this moment, the hotlist of this resident family stopped metering, and neighbours will bear more hear rate around it.Simultaneously heating system is also in heat radiation, and it is irrational at this moment not measuring the system radiating that the user that turns off the heat supply valve should bear.
Summary of the invention
Use a heat meter to carry out the problem that household metering exists in actual applications at each user, task of the present invention is exactly the method with the heat separating user metering of the constant indoor temperature of design one cover brand new ideas, make resident family more convenient, measure with heat that more science is more reasonable with heat.
The basic design of the method is at first each all to be set under the identical temperature with indoor temperature, measures the overall heat consumption (Q of sub-district heat supply in the setting-up time section again with a heat meter
Always), re-use each user in the device patrol record provided by the invention sub-district in during this period the hot time of actual usefulness (t) and the time (t ') of heat of no use, because each user's area of heat-supply service (S) is known in the sub-district, the indoor of each user all is set under the same temperature simultaneously.So just can calculate in the official hour section hear rate on every square metre of area of heat-supply service, and then calculate the calculating heat of each household in during this period, its calculation procedure is as follows:
(a ') its computing formula is as follows:
