A kind of room temperature is identical uses the heat separating user metering method
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:

1 double-break switch among Fig. 1,2 temperature detect switch (TDS)s, 3 solenoid valves, 4 relays, 5 switching input modules, 6 heat meters, 7 Programmable Logic Controllers, 8 computing machines; A constant indoor temperature control circuit, b system signal circuit.
Embodiment
In conjunction with Figure of description 1, the constant indoor temperature control circuit a that this method is composed in series by double-break switch, temperature detect switch (TDS) and the solenoid valve that contains each user; The heat of using that contains each user in system and device that system signal circuit b that each user's relay, some switching input modules, Programmable Logic Controller and heat meter form and the computing machine 8 that finally reads hot continuous data constitute and the corresponding application metering sub-district thereof.Wherein constant indoor temperature control circuit a connected mode is: the stiff end of double-break switch is connected with an end of power supply, connects arbitrarily with temperature detect switch (TDS) and solenoid valve with a contact of double-break switch, inserts the power supply other end then; The connected mode of system signal circuit b is: another contact of above-mentioned each user's double-break switch 1 is connected with an end of relay 4 coils; The other end of relay coil is connected with the other end of above-mentioned power supply, and the tip side of relay is connected with the input end of switching input module 5; The communication port of switching input module plays corresponding input interface with Programmable Logic Controller and is connected, and the signal output part of heat meter 6 is connected with above-mentioned Programmable Logic Controller 7 corresponding input interfaces.
In conjunction with Figure of description 2, at first the temperature detect switch (TDS) with each user in the sub-district all is set in (as 21 ℃) (step 10) under the identical temperature, be area of heat-supply service constant and the heating system heat radiation time coefficient assignment (step 20) of each user in the system and device application program then, the cycle of initialization system device for reading data is 24 hours (step 30) simultaneously.Programmable Logic Controller 7 reads the sub-district that heat meter 6 measured by the cycle of setting and always uses thermal data (step 40).In the section cycle length of above-mentioned setting (24 hours), switching input module 5 patrols and examines and writes down the closing of each user's double-break switch of access, disconnected state and duration (step 50) through relay 4, just hot time of user's usefulness and establishing the hot time of using; During this period, when user's heat, with double-break switch 1 closure, this moment, room temperature was lower than the temperature (21 ℃) that temperature detect switch (TDS) 2 sets, and solenoid valve 3 is opened, and heating system begins to indoor heating, and room temperature raises; When room temperature was higher than the design temperature upper limit (as 22 ℃), temperature detect switch (TDS) disconnected, closed electromagnetic valve, and heating system is suspended heat supply; When room temperature is lower than the lower limit (as 20 ℃) of design temperature, the temperature detect switch (TDS) closure, solenoid valve is opened, and heating system is heat supply again, thereby realizes indoor thermostatic control, and this moment, the closure time of double-break switch was the above-mentioned hot time of using; When the user need not be hot, double-break switch is disconnected, closed electromagnetic valve, heating system stops heat supply, and be the above-mentioned useless hot time trip time of double-break switch this moment.Press the cycle of above-mentioned setting then, Programmable Logic Controller 7 reads each user's heat time and the hot time data useless that all switching input modules are write down in the said system signal circuit b, heat is always used in the sub-district of being read according to each known in sub-district user's area of heat-supply service and step 40 again, according to above-mentioned formula share metering and add up each user with heat (step 60).The register that has been read the switching input module metering time data of data makes zero, and above-mentioned then module is restarted the patrolling and examining and writing down of next cycle time period (step 70 is returned step 50 then).Regularly gather user's heat information, tabulation, the printing (step 80) that Programmable Logic Controller 7 is stored with computing machine 8 at last, as the foundation of collecting the charges.Thereby finish temperature control and hot purpose of measuring that the present invention will reach.
