Abstract
The invention relates to a centralized heat supply measuring and charging method. A real-time effective area distribution method for heat energy comprises the following steps of: for a heat energy distribution accounting unit, checking the room area of each user, and correcting the room area to obtain an effective area of the user; then according to a ratio of the effective area of the in-use room of each user of a heat supply region in a certain unit time to the effective area of the in-use rooms of all users, performing real-time distribution on the instant heat energy values of total heat energy meters of the heat supply region in the unit time; and accumulating the real-time distributed heat energy value distributed to each user from one certain moment to the other moment to obtain a distributed total heat energy value of the users in the time period as basis for heat supply measuring and charging. The method realizes on-demand measuring and charging of centralized heat supply/warming with low cost by distributing the heat energy through the real-time effective area and canceling a heat energy meter; and the charging method is scientific and reasonable, is easily accepted by the users, and has low equipment investment cost. The method can improve the energy-saving consciousness of the users, and is favorable for saving energy.
Description
One, technical field: the present invention relates to a kind of central heating metering and billing method, particularly relate to the real-time actual effect area distributions of a kind of heat energy method.
Two, background technology: in the total energy consumption of the social energy of China, resident's building heating energy consumption occupies suitable pith.Because at present most building heatings all are to collect heating cost according to user's construction area, and no matter the user with still need not, with many or with lacking.This has just reduced the enthusiasm that the resident saves heating energy consumption greatly, has caused very big energy waste unintentionally.
In the motive heat distribution system, the calorimeter allocative decision is a charging method the most rational.Theoretically, the calorimeter allocative decision adopts calorimeter to be installed in every household, and just as ammeter, water meter accurate recording this family energy consumption, according to the data of these energy consumptions, no matter the area size can accomplish how much energy to pay how many expenses with.But because the integrating of heat energy has higher requirement to the temperature difference and flow, and present design, manufacturing process can not guarantee these data stability, special heat energy table for low discharge, adaptability is poorer, service life is shorter, the maintenance and repair cost is very high, and input and benefit are not complementary, and have been fade-in difficult boundary.This is the shortcoming of an essence of present calorimeter allocative decision existence, and equipment has high input, and operation cost is very high.Present popular " time and area apportion design " heat energy allocative decision, the chances are according to the time of using heat energy and use the area of heat energy to calculate for the principle of its distribution.Result calculated is that the time of heating is long more, and the area in room is big more, and obtaining energy will be many more.But actual conditions but are, the user uses the length of heat energy time and the size of room area, be not the many and few whole factors of this user's heat of decision, different users is in different time heatings, even the time of heating is identical, the heat energy that they obtain also may be inequality, only judges with the length of heating time how much what obtain heat energy is unilateral.
At present, implementing its profound reason of household metering is to be means with the economic lever, encourage the user can be initiatively when not needing to heat, conscious valve-off stops or reducing heat supply, promotes to save minimizing energy waste, aim of saving to reach.Since the heat energy of heating also is a kind of commodity simultaneously, adopt scientific and reasonable charging way just can show social equity so.Current heat energy allocative decision except heat energy table real time measure is still measured not enough science, rationally, is unfavorable for encouraging the user that untapped room thermal source is turned off with flexible way energy savings more.
In a word, " time and area " or similar heat energy allocative decision, only utilize the length of heating time, and do not differentiate the heating temporal differences, cause to distribute and have bigger error, user's entire area is participated in the distribution as fixing data in addition, thereby have certain limitation, promotion user partial that can not be strong warms oneself energy savings.
The user heating heat distribution scheme of science can accomplish to help to improve the consciousness that the resident saves with heat and paying close association, to user and even entire society, all has considerable society and economic benefit.The characteristics that rational heat energy allocative decision should have: 1) rational heat energy allocative decision of having cast aside the heat energy table, should be one and have good physical model structure, the correction factor K formation mechanism that the provides energy science, indubitable, convenient, clear, the plain Numerical Calculation Method that provides, thus be easy to the scheme accepted by users.2) though cast aside the heat energy table, system should remain the distribution system of an actual heat.What of user heating expense, can only with how much being associated of its energy charge, should be not only and the insulation rank in the construction area in house, house, external condition such as whether window be associated.3) on the heat energy allocative decision, should be able to give the gem-pure consciousness of user, how many expenses that pays with how many heats exactly, whenever turns off a fin, and how much you just can save.4) system should have the conscious raising insulation of the user of allowing measure, the function of energy savings.Avoid because of destroying warming measure (windowing such as malice), malice changes sample temperature and escapes the function of paying.
Three, summary of the invention:
The present invention is directed to the prior art deficiency, propose the real-time actual effect area distributions of a kind of heat energy method, cast aside the heat energy table from the heat energy allocative decision, but system remains the distribution system of an actual heat.What of user heating expense, only and what, the real-time actual effect area in house of its energy charge be associated, the insulation rank in the house of getting along well, external condition such as whether window are associated.
The technical solution adopted in the present invention:
