Study On The Characteristics Of Indoor Thermal Environment Monitoring Points Under The Heating Condition Of Air Conditioning

As a common adjustment method of indoor environment,accurate air conditioning relies on the monitoring of the indoor environment.For the indoor environmental parameters’ detection process,the relevant standards have already had clear requirements for the arrangement of measuring points,but the requirements are usually difficult to meet the demands of indoor environmental monitoring points.Therefore,the study of the distribution of indoor thermal environmental parameters under the heating condition of air conditioning based on the requirements of relevant standards to know the characteristics of the monitoring points at different locations under different working conditions is very important.In the current research on the distribution of indoor environmental parameters,both experimental testing and numerical simulation are commonly used research methods.In the research on the optimization of the location of monitoring points,there are relatively few studies on the analysis of the characteristics of the monitoring points based on the distribution of indoor environmental parameters and the actual requirements of the monitoring points’ layout.Based on this,the work is as followed.First of all,by sorting out relative standards,the specific requirements of the layout of indoor environmental measuring points and the testing instruments are clarified.Take the requirements and the actual condition of the experimental demands and laboratory layout characteristics into consideration,this paper makes the arrangement of measuring points and the selection of instruments to complete the construction of the laboratory’s indoor thermal environmental monitoring platform.During the experiment,the indoor thermal environmental parameters under 9 different air supply parameters are continuously monitored,and the parameters of the indoor environmental boundary condition under 9 working conditions are tested.Secondly,the monitoring results obtained in the experimental tests are analyzed.The analysis is about the volatility of the monitoring results,the overall distribution differences of the monitoring results,and the temperature and relative humidity distribution characteristics in the vertical and horizontal directions,and it can obtain the temperature and relative humidity changes at different measuring points over time.Finally,based on the simulation theory and measured data,the indoor temperature and relative humidity distribution under 9 working conditions are numerically simulated,and the temperature and relative humidity distribution under each working condition is obtained.Based on the measurement points determined by the experimental tests,the corresponding temperature and humidity cloud images in all directions are obtained.Combined the simulated results with the actual measurement results,this paper gives a comprehensive analysis of the characteristics of the indoor thermal environment monitoring points under the heating condition of air conditioning.
