Study On Design Strategy Of Unit-typed Office Spatial Natural Ventilation In Summer Time At Severe Cold Region

Use of air conditioning equipment to improve the indoor environment in the room need to keep closed when such cases because indoor air is not an effective replacement,leading to indoor air quality.Sustainable development based on building needs,use of natural ventilation to improve indoor thermal environment back into sight.Through the use of natural ventilation to improve indoor environment can effectively reduce the building's energy consumption.Air quality has improved for the room,so by introducing fresh air with natural ventilation to the Interior,ensure a comfortable indoor environment.Use of air conditioning and mechanical ventilation equipment need to consume large amounts of energy,in order to reduce energy consumption,people pay more attention to the use of natural ventilation in recent years,while helping to reduce the use of air conditioning and bring disease to the body for a long time.Paper first discusses concepts related to Office space and natural ventilation in cold area,through to the cold climate,natural ventilation action principle of ventilation elements,Office space,and natural ventilation and thermal comfort analysis,using it as a basis to propose subsequent simulation of boundary conditions and standards.Secondly,through the Office building in cold area of the modular office space to conduct field investigation,research units of office space in the Office building of natural ventilation in summer,summed up the two typical physical model--the single window with double window-type units of office space.Based on the numerical simulation analysis of two units in the Office space.Used Airpak software unit of office space in two typical models simulate the velocity,temperature and age of air,air path and PMV and PPD field analysis of indoor thermal environment in Office space.Finally,summarize existing modular office space problems and propose appropriate optimization strategy.Results of this research can provide data for the design of a modular office space references and has some significance,lay the Foundation for further study,with a view to promoting sustainable development of modular office space.
