Annual Air Infiltration And Energy Consumption Of The Regional Studies

Air infiltration energy consumption holds the very great proportion in the building energy consumption, so it's not to be sneezed at. The development of energy efficiency in buildings, the use of energy efficiency windows and doors, as well as the consummation of air infiltration computational method, provide foundation for reducing air infiltration energy consumption, simultaneously also set the urgent request for the study of air infiltration energy consumption partition. At present the study of energy efficiency in buildings involves very little to air infiltration energy consumption in our country, moreover has not the study of air infiltration partition. In the meteorological aspect, the outdoor meteorology parameters needed in annual energy consumption calculation is still incomplete at present, while the correlation theoretic models are too complex to apply in the project.In view of above questions, this thesis studied air infiltration partition based on the conception of infiltration degree-hour and the simplified three-wave model. The primary completed research work is following items: According to the air infiltration computational method in "Code for design of heating ventilation and air conditioning" and the infiltration degree-day concept of America, the thesis presented our national concepts of heating infiltration degree-hour and cooling infiltration degree-hour, which can directly show the size of annual infiltration load and provide theoretic basic for the infiltration degree-hour calculation; The simplified three-wave model was established. It was proved feasible by calculating the infiltration degree-hour of five typical cities. So the meteorology parameter was provided accurately for annual infiltration lode; Based on the model, the theoretic risk of climate designing data from our country and "ASHRAE foundamental handbook" was analyzed; The tendency of infiltration energy consumption along with the floor, the building, region, air tightness grade of windows were also analyzed; Finally, this thesis applied fuzzy clustering analysis method to zone the national main cities. An infiltration partition map was formed, while all cities were grouped into six categories. In order to reduce infiltration energy consumption adjust measures to local conditions, different partitions should take different infiltration energy efficiency measures.
