Improved value of temperature different on climatic chamber climatic chamber for thermal conditions

摘要

Climatic chamber machine at Climatherm laboratory was used for thermal test on wall model.This climatic chamber machine allows the measurement of different environmental variables.In this research, thermal performance tests were conducted on wall model imposing boundary condition vary the cavity distance between two wall elements and then these tests were performed in steady-state conditions.Wall model prepared from aluminum composite and was maintaining controlling the air temperature difference between the two chambers 20°C and the air debit constant.In the first part of this paper, a description of the climatic chamber machine, operation ranges, and theoretical work principles of the climatic chamber are presented.Then, the second part shows the results for the thermal test on wall model.The thermal test performed with the climatic chamber machine allows simulating environmental conditions accurately during in certain distance of cavity and specific air debit.As a result, the configuration settings value at the climatic chamber machine has to correction to reach the air temperature difference as planned.The air temperature difference at the beginning of the thermal conditions on wall model is less than the planned air temperature difference.However, this correction value of temperature shows agreement result with the value 20°C in temperature different.
