A Research On The Temperature Response To The Intermitting Heating In A Room With Composite Material Walls

Directing against the relationship between the thermal comfortableness of human bodies and the room and the inner wall temperature, a mathematical model was proposed and tested for the room temperature response to the intermitting heating in a room with walls built with composite materials. Numerical results indicate that the arrangement of the material has significant influences on the room temperature response curve, under the identical heating (refrigerating) condition, with the composite material wall formed by the identical materials and the same size. This will greatly affect the comfortableness of the human body in the room with intermitting heating. The research work includes three aspects:The first is the theoretical study on the room temperature response to the intermitting heating. According to unsteady- state heat conduction theory,the various temperature change detail theory model about the various structure room was proposed,In order to describe the temperature change law of structure itself when indoor or outdoor condition change . The mathematical model about the various structures room is synthesized together , on this foundation,the instantaneous energy of the room was balanced,and the normal differential coefficient –partial differential coefficient equation model about the temperature response to the room with walls built with composite material was built,and finds the solution to mathematical method of this model. So, the room temperature response to the intermitting heating in a room with walls built with composite material wall is connected with the factor such as the external environment temperature of building and the hot physics property parameter, size of structure and the type of structure and the initial appearance of indoor as well as the quantity of heat supplying of room etc. The second is study on the calculation and experiment of the temperature response to the room with walls built with different interior material. Firstly , base on the theory model of the room temperature response to the room with walls built with composite material,the hot property of trends under the hot condition was analyzed about the intermitting heating room formed by the different structures,that structural parameter and hot physics property parameter influence upon indoor temperature response was quantified. The major influence factor among them was ascertained .Then ,one set of 1:1 was built inside a typical room the trial system of the different inner surface materials to carry on pair-comparison testing, the air temperature of indoor and the interior wall surface temperature under the different conditions was measured. The third is study on the calculation and experiment of the temperature response to the room with walls built with the material in different order. In allusion to the same building model, we studied on the calculation and experiment of the room temperature response to the room with walls built with the material in different order, that verified what difference among those about the room temperature response to the intermitting heating room.
