Based On Architecture In-Between Space In Hot Summer And Cold Winter Climate Zone Ventilation Strategy Reserach

This study first reviews and explain the concept of In-Between space and the research method employed for building ventilation.In-Between space refers to a space with the coexistence of multiple spaces in architecture.Its relational,spontaneous property and public characteristics help improve the transformation ability of alternating architectural space experience.Based on the study of the interaction between In-Between space and building ventilation,a classification method of InBetween space is proposed,which takes the degree of interface exposure as the main characteristic parameter.The open interface and regular hexahedron were mapped by this method,and the mechanism of building ventilation in In-Between space was studied through the regularization of space.The analysis of measured data shows that the superimposed effect of openness and shading improves the cooling effects of the corridor,and the cooling effect of the combination of corridor and the In-Between space shading is closely related to the scale of overlaps,orientation,and occupied time.Then,three traditional two-story buildings in the middle and late Qing Dynasty in Changsha are selected for investigation in hot summer and cold winter regions,based on the classification method of buildings from four dimensions,including space category,traditional architecture,time category and multi-story architecture.Through the integrated of geographic information technology and building information technology,the digital twin models of the buildings are created,and then the thermal and humid environmental data of the buildings are collected in the In-Between space.The main characteristic parameters of natural ventilation in the In-Between space are measured and analyzed.Based on the BIM models,the plane area of the In-Between space,the comparison of the form and function of the intermediary space,as well as the combination mode of the intermediary space are analyzed and evaluated.The results show that the intermediary space accounts for about 70% of the first floor and 30% of the second floor of the traditional building.By studying the rules of In-Between space through the restoration of the scene of the buldings,it is revealed that the traditional architecture presents strong regional comprehensiveness and complexity,which is highly consistent with the similar characteristics of the modern complex architecture.At the same time,it is found that the integration of traditional architectural In-Between space plays a decisive role in the overall morphological characteristics of architecture.The thermal pressure effect of patio and pavilion is verified by temperature stratification test.The combination of patio and pavilion and the combination of patio and courtyard can both enhance the ventilation effect,and the effectiveness of ventilative cooling can be guaranteed and strengthened by setting multi-directional vents.In this paper,the coupling mechanism of plane scale,floor number,hall and cross ventilation effect on the natural ventilation of surrounding rooms is studied based on typical In-Between spaces such as patio,covered hall and open hall.The results show that: 1)When an In-Between space is created in a building,it is easy to form a ventilation corridor in the interior to promote indoor air flow and improve its own heatsinking ability and indoor thermal comfort.Therefore,it is necessary to set up InBetween space and for ventilation design;2)When the size(length and width)of the patio decreases,the heat gain due to solar radiation in the patio decreases,and the average indoor temperature decreases,and vice versa;3)When the height of the patio increases,the shading effect of the patio of the surrounding rooms will be strengthened,and the temperature in the patio will decrease;The more the hight increases,the closer the temperature in the bottom patio will be to that in the surrounding rooms.4)In traditional buildings,thermal and wind pressure effects are mainly due to ventilation openings,corridors,and floors,and forced wind pressure effects(such as fans)are used to reduce indoor temperature and improve thermal comfort.The results show that: 1)when the patio and room are combined,the setting of the patio is beneficial to increase the solar heat gain in and around the patio and form a large temperature gradient,thus promoting the ventilation due to thermal pressure;2)When the covered hall is combined with the room,the setting of the covered hall can not only increase the solar heat gain of the intermediary space,but also reduce the thermal pressure effect due to the shielding effect of the covered hall,making the temperature accumulation effect of the covered hall and the surrounding intermediary space more obvious,thus promoting the ventilation due to thermal pressure;3)There is an optimal proportion of the size in the cover hall to achieve the best cooling effect on the cover hall and surrounding rooms.Therefore,it is beneficial to improve the natural ventilation and cooling effect of the In-Between space and surrounding rooms by fully considering the openings,doors or windows and the organization of the In-Between space in architectural design.Finally,the coupling strategy of renewable energy application technology and building ventilation technology is studied.Taking solar ventilation technology and wind tunnel technology as an example,it is found that,the core principle of renewable energy application to promote building ventilation is to expand the application of thermal pressure effect and wind pressure effect,and the application strategy on coupling of the two technologies is proposed.The application of passive solar ventilation is to improve the thermal pressure effect;Wind tunnel technology combines the effects of thermal pressure and wind pressure.Through the construction and integration of more than ten spatial scenes,two typical intermediary space groups are proposed,and the application modes of traditional architectural principles and scene mapping in modern urban complex scenes are analyzed and studied.The concrete construction form and air flow organization solution of single design and technical strategy are put forward,and the possibility of integration of multiple architectural ventilation design and technical strategy combination form is explored.Taking urban complex as an example,the application methods and modes are studied from two aspects of coupling the ventilation design strategy of traditional building In-Between space and innovating the coupling ventilation technology strategy of renewable energy technology.Through the construction and integration of more than ten spatial scenes,two typical intermediary space groups are proposed,and the application modes of traditional architectural principles and scene mapping in modern urban complex scenes are analyzed and studied.The structure form and air flow organization solution of single design and technical strategy are put forward,and the possibility of integration of multiple architectural ventilation design and technical strategy combination form is explored.Finally,the coupling strategy of renewable energy application technology and building ventilation technology is studied.The main contribution of this paper is that,by disitinguishing core concept of InBetween space,the author endows it with the attributes of relationship,spontaneity,public and attributes that can integrate two kinds of space without losing their own characteristics and puts forward a research method of classifying In-Between space with the degree of interface openness as the main characteristic parameter.Through integrating the technology of information collection and cloud data collaboration,field investigation is carried out to establish the digital twin model.Through field testing and simulation,the influences of ventilation openings,corridors and floors on the thermal pressure and wind pressure effect of ventilation was studied.Simulation of typical InBetween space was carried out to analyze the mechanism and performance of ventilation coupling strategies,including patio size,covered hall size,open hall size and the combination of different In-Between space,two typical intermediary space group modules are proposed,and the reconstruction and integration analysis of more than ten spatial scenes show the potential of application of traditional architecture scene mapping in modern urban complex scene.By expanding the application of thermal pressure effect and wind pressure effect,the integration of renewable energy ventilation technology in modern urban complex is analyzed.
