Research On The Design Of The New Air Conditioning System Of Museum

This paper first describes the architectural features of museums and museum’sspecial requirements of the indoor temperature and humidity of the environment, andemphasizes the importance of airflow organization form for air conditioning.Seekingthe reasonable airflow organization to meet the requirements of human comfort andenergy conservation.And the airflow of air conditioning system is introduced in thispaper.Describes the research method of airflow organization classification and theairflow organization, and focuses on the CFD simulation method.By comparing the jetformula method, Zonal Model method, CFD method and model experiment method,analysis the difference of these methods, so as to find the most suitable method isapplied to the engineering practice and research, and it is CFD simulation method.Thanthe model experiment method the CFD simulation method for calculating cost is lowand than jet formula method and Zonal Model method it is high,so it is suitable for theengineering practice and research.Since the CFD simulation method has so many advantages, the paper choose CFDsimulation method, and then introduce the CFD simulation method.Introduce thetheoretical basis of CFD and application software of CFD.And then introduce the basicmodel and the method of control equations and CFD fluid dynamics.The research ofmuseum organization airflow focuses on the simulation of humidity field simulation,sothe component transport equations have been focused analysis and researched.This paper presents the slot used for Museum showcases air-conditioning,compared to the original Museum of airflow and sent back.This paper presents the slotblowing using for Museum showcases air-conditioning,and compared to the originalMuseum of airflow.Uses FLUENT to simulate two kinds of air distribution in differentconditions.Comparing the simulation results with two different air distribution, analyzedthe difference of the two kinds of air distribution under different working conditions,and described the existence of the original flow organization problem, on which methodis more suitable for the Museum of air conditioning.Finally we have a conclusion.This research indicated that, compared with the slot blowing diffuser to supply airand sent back the tuyere, slot outlet can meet the design requirements and can saveenergy.Because the slot outlet installation is simple, beautiful, and the entrainmenteffect is small, so it is much more suitable for the museum building than cyclone outlet.
