The present setup is designed to study the heat transfer through composite walls. It consists of a heater sandwiched between a composite structure having three different types of slab on either side. A small hand press frame is provided to ensure the perfect contact between the slabs. Heat produced by heater flows axially on both the sides. Temperature Sensors are embedded at the interfaces of slabs to determine the temperature gradient. The experiments can be conducted at various values of heat input and calculation can be made accordingly. Electronic energy meter is provided to measure the heat input. It has an interfacing unit designed along with Lab view software. This educational software allows/enables user to log the real time experimental data and tabulate the experimental/sample reading according to the requirement of experiment. User have a control on data logging, printing the stored data and preparing spread sheets in Excel. Flexible graph plotting facility is also available in the software.

•Cabinet to accommodate the slab assembly with front window of acrylic.

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.

Experimentation/Learning Objectives

•To determine total thermal resistance and thermal conductivity of composite walls.

•To plot temperature gradient along composite walls.

Utilities Required

•Electricity Supply: 1 Phase, 220 V AC, 50 Hz, 5-15 amp combined socket with earth connection (Earth voltage should be less than 5 volts)

•Table for set-up support.

•Computer System: i-3 processor with DVD Drive, Windows 7, MS-Office pre-loaded. One USB slot required in PC for Data Acquisition Card.
