Description
Technical field
The present invention relates to a kind of industrial The application of single-chip computer technology or single-chip microcomputer application technology at the central heating management domain, specifically a kind of contactless heat, cooling two-purpose intelligent control individual household metering device that is used for central heating is hereinafter to be referred as " intelligent control individual household metering device ".
Technical background
The basic situation of central heating at present is as follows:
(1) China is vast in territory, heating phase, heating system difference are very big, and some local heating have produced immense pressure to local finance, some enterprises also by heating press unable to breath, the contradiction that produces because of heating day by day intensifies, the country also do not have a special relevant law come standard it.As if in the past few years, the heat supply system reform makes slow progress, and some places still stop on the table so far, also do not find the breach, or found also and do not thought.
(2) China's concentrated supply of heating in the city area is to reach more than 1,100,000,000 square metres, indoor heating system is almost all being kept the heat supply network framework of the vertical series and parallel heating of planned economy payment at a lump rate in period formation in period, and the code of building design of Sheng Chenging has been strengthened the continuation of this system conversely again therefrom.Building energy conservation old does not change, new coming again, or even before build after changing, the speed of transformation has indomitable vitality far away from the speed of building.But, the enforcement of the extremely incompatible existing calorimeter metering method of this heating system, the lesson of the heat supply reform that in the past few years has no effect is told us: allow existing building deacclimatize the condition of work of that piece calorimeter simply if continue, this too idealized, changeable in mood pursuit, huge engineered and high cost will make " household metering " to face stranded danger.
(3) existing central heating user's room, the insulation of building energy conservation and air-tightness are too poor, almost all do not meet the standard of building energy conservation, it no matter is welfare house-purchase in the past, in the sale of still present the commercial house, the factor of this standard is not embodied among the house selling price all the time.Have material to claim: the thermal loss of building bottom, top layer and exterior wall (cold wall) generally can reach 20%, after " household metering ", because of the dispute that this factor produced is difficult to solve.If this loss " was not made clear " originally because of house-purchase can be by the user from accepting one's bad luck; So, because of neighbours need not warm up the heating equipment operation fixed expense of being paid during one, should how to be divided into heat supply department.(according to the way of existing pilot, heating cost is made up of with two parts equipment operation fixed expense and meterage)
(4) continuing to use for many years the method by area charge, change into by the way with the charge of heat household metering, not only make the operation of heat supply department and accounting that great variety has taken place, also is a completely new concept to the user.Thermal property has determined its different sub-water, electricity, coal gas, Every household has an ammeter can not solve unreasonable in the charge for prior art, contradictory all to want to rely on this piece table to solve also be unpractical the institute of heat supply reform, and the user really needs is not heat but indoor temperature.Thermal property has determined to reach same temperature, the house of living with the resident relevant, also relevant with exterior wall (cold wall) and phase neighbours' heating position towards, level, and it is different therefore causing the heat of consumption.How much the user will spend, buy what caloric heat just can spend severe winter, is entirely ignorant of, and says nothing of life and has planned.
(5) China utilizes the existing resources such as pipeline, equipment of urban heat supplying system, develops refrigeration, central cooling and also is in conceptual phase, the existing example report of developed countries.This will be a sizable market, in case exploitation will be accelerated the process of " household metering " and excite interest and the expectation of people to the cold, hot two-purpose measuring apparatus.
In sum, urban heat supplying exists the entanglement of cutting constantly, managing also random every aspect from beginning till now.In addition, heat is a kind of special commodity, exists conduction, convection current, three kinds of pipelines of radiation, is impossible if will isolate completely it in the room, has also lost the real meaning of city heat supply reform.

Though directly or more directly heat supply is measured, also should be accurate on the principle, but price is more expensive, install complicatedly, the layout of heating system is had special requirement, and when low discharge, error in dipping is bigger, simultaneously, be subject to the influence of tube wall corrosion degree, bubbly water foam or impurity content, pipe vibration, and the interference of human factor.
The present situation of present " household metering " technology is:
The first, the building energy conservation weak effect, existing factory (storehouse) room, office occupancy and resident are with all building constructions such as rooms, except that have specific use, general heat insulation effect is too poor, and body of wall, the support of floor and the effect of partition have just been emphasized in architectural design, building thermal insulation material is lacked pay attention to.As: heat-preserving walls etc. are not widely used in building construction so far.
The second, the heating system design is unreasonable: the heating system of existing residence building is the vertical series and parallel heating system of planned economy payment at a lump rate in period formation in period mostly.According to existing calorimeter metering method requirement, the indoor heating system must be designed to two-tube level parallel connection (or the series connection of single tube level), the indoor heating system must divide family Cheng Huan.This means and all to make a new start, therefore realize that household metering has certain degree of difficulty the heating system of original heat supply user.In addition, inefficient problem in the heating system, for example heat supply control, system's imbalance, water quality inferiority etc. all affect the process of " household metering ".So, the metering method of prior art existing deficiency in actual application is: heating charging is that unit calculates by heating season and heating building area, no matter you live and do not live, the people is arranged with unmanned in the family, also no matter winter is long and weak point, completely a price, therefore the masses think one-sided agreement, consequent dispute also is in rapid succession, and some infrastructure management company externally claims, and " owner in the sub-district I complete accuse all over ".
