Research On The Energy Efficiency And Economical Analysis Of Heating Meter

Due to the research of heating meter and temperature control in our country at the first stage, some issues and problems has come out. The questions are how much the energy efficiency for heating meter system is, and whether energy saving profit is more than the investment of the epuipment. These are hot issues. This thesis makes reseach on the following.Based on the principle of heating tariff constitute, the structure of heating tariff was analysed. Take Yingkou and Benxi as example, the present and forecast heating tariff are obtained.When heat is as commodity, and heat measurement and temperature control are installed, residents can filledly use free heat. Adjusting temperature by residents encourage enthusiasm of users and heating company to enhance energy efficiency. This thesis devides the energy efficiency. The energy efficiency envelope insulationη₁, the energy efficiency of free heatη₂ , the energy efficiency of behaviorη₃, the total energy efficiencyηrelative to the building without energy saving, and the total energy efficiencyη'relative to the building with energy saving are defined in the thesis, what's more ,the relation among them are also given. By the energy simulation software EnergyPlus, the thesis give the simulation result of energy consumed for heating by the building without energy saving ,the building with 50% energy saving and the building with 65% energy saving in typical cities in different climate zone. On this basis, the thesis analyse the proportion of the energy consumed by the envelope, infiltration and free heat and achieve a series of energy efficiency such asη₁,η₂,η₃,ηandη'.The thesis ascertain the callback period according to the investment of meter and the energy saving profit at the actual heating tariff on the condition of different manner of heating meter.
