Experimental Investigation of Air Conditioning in a Bi-climatic Room

Abstract

This paper is a preliminary study to the investigation of hygrothermal behavior of wall implemented as separating wall of bi-climatic rooms. One room simulates indoor environment while the second simulates exterior climatic solicitations (temperature and relative humidity). Four typical Tunisian winter climate are selected for this study. The aims are to check the homogeneity of ambient conditions in the rooms, the reaching of the set point, the delay to reach it after setting then if the ambient conditions remain constant once they are reached, and finally the response time of the whole system. The results underline that some climate are easy to reach while other may be difficult to obtain due to competitions between climatic systems. This may be solved by acting on the device management. The typical response times are short enough to plan daily cyclic variations in the following steps of the study and ambient conditions are homogeneous in the room.
