Correction And Achieve On-off Metering Heating System

By changing the existing owners and heating companies charging system, willmobilize the environmental awareness of the owners, the building of a waste of energyin winter serious situation fundamentally resolved. So the introduction of the concept ofhousehold heat metering, heating system opens up new directions for reform. A varietyof measurement systems have sprung up, but many household heat metering systemsneed to change the settings of old housing pipeline, which requires a lot of money toadvance to the initial investment which.Having studied the theory of pre-verification, we found that there are manyadvantages of time-off area method, small changes in the measurement system on thebasis of the existing pipeline, the minimum initial investment, and temperature controlto good effect. Meanwhile, in the absence of heating enterprises to improve the capacityof the premise, to meet the needs of the majority of owners, in addition to householdadjust the room temperature to ensure the smooth and comfortable indoor temperature.However, there are many problem that the metering system, in actual use, often thesame temperature set by the user, but a huge difference to pay heating costs. The maincontents of this study is how to reduce the impact of heat transfer between householdsmetering system at the same time improving its fairness to ensure that heatingcompanies will not be a loss. For heat transfer between households, there are manyapproaches, this paper proposes a new way of thinking. Among households determinedon the basis of heat transfer, in accordance with its specific amounts reflected in thecosts of heat to change its fee structure，to improve the fairness of the system.Through FLUENT software to build indoor temperature fluctuations model. Inorder to ensure meaningful simulation room, a large collection of literature in this article,to accurately calculate the heat capacity of the wall, and as a basis for simulation. Bysimulating a separate room heating, cooling process, in order to determine the location of the room and control points, and then use the software FLUENT UDF modules, PIDcontrol to ensure that the model is stable indoor temperature. Acquisition of adjacentheat transfer value difference room thermostat in order to determine the heat transferbetween the user’s exact value, and as a basis, and gradually analyze the impact of heattransfer between households of household heat metering system.The use of household heat metering heating system, usually two system fee. In thispaper, the two start heating fee structure, fee structure reallocation heat, changinghousehold heat metering charges, thereby reducing the heat transfer to the charge ofinterference between households.
