Study On The Thermal Environment Of Residential Cluster Based On Layout Pattern In Winter

Cluster thermal environment means that the 3D thermal environment which be composed of the indoor of building and the outdoor of cluster. The study on cluster layout pattern, it is not only contributing to improve the climate adaptability, terrain adaptability and environment adaptability, but also providing the optimization plan for the residential plan that can reduce the building energy consumption with contenting the quality of the resident environment.In view of the architectural technology, the thesis combine to the way of the theory analysis simulation calculate and investigation:At first, Thorough describing the physics process of the building thermal of cluster, the thesis analysis each impact mechanism of cluster indoor and outdoor and the doubleaction process of the indoor and outdoor heat-attected. It is grasped the conformation mechanism of the cluster microclimate and is abstracted mathematical model.Secondly, a union simulation program for the cluster thermal environment and building energy consumption is given. It is based on the thorough analysis of its thermal process as well as the integrated and accurate calculation of the relevant factors and adopting the way of success iteration to solve the problem of atmosphere parameter in the simulation of the thermal environment. Look on the simulation data of the CFD software as the import data of the building energy simulation software. Thorough the residential synthesis experiment, the thesis analysis and found that the simulation forecast digital approach the measuring digital. It is be proved of the accuracy of the simulation programmer.Then, for example in Xi'an, with lots of numerical example experiments, under holding the indoor temperature, the thesis successively change the cluster layout parameter that the designer care and obtain the optimization cluster plan that looked energy consumption on as reference for the diversify cluster layout by the simulation programmer. The optimization cluster plan is:the north building and the south building are all L shape, the building energy consumption is the lowest when the openning of enclosed layout lived in the east side and the ratio is 2:1; the building energy consumption is the lowest when the distance of solar is 1.2H in the array layout; the building energy consumption is the lowest when the north building and the south building is compare to 1.5:1; the building energy consumption is the lowest when the wind projection angle is in the 30 degree-45 degree; the north building is L shape and the south building is line or the south building is L shape the north building is line, the building energy consumption of the semi-enclosed layout is the lowest when the shape scale ratio of the L shape building is 0:1:0.5.The effects of some important the cluster layout are compared quantitatively for the.thermal environment and building energy consumption. It should be combined the thermal environment design with the architecture design. Thorough the architectural technology measure, it is be provided the optimization plan at the form combination for the designer in the plan prime.
