Energy management system for the household appliances in terms of monitoring and control
is described in this paper. Monitoring the energy consumption is the initial step to reduce it …

Abstract The Heating, Ventilating and Air Conditioning (HVAC) system has large thermal
inertia, pure lag time and nonlinear characteristic. Furthermore the plant is susceptible to …

4-1C In heat transfer analysis, some bodies are observed to behave like a" lump" whose
entire body temperature remains essentially uniform at all times during a heat transfer …

3-164 A circuit board houses electronic components on one side, dissipating a total of 15 W
through the backside of the board to the surrounding medium. The temperatures on the two …

3-127 Hot water flows through a 5-m long section of a thin walled hot water pipe that passes
through the center of a 14-cm thick wall filled with fiberglass insulation. The rate of heat …

3-83C In a cylindrical pipe or a spherical shell, the additional insulation increases the
conduction resistance of insulation, but decreases the convection resistance of the surface …

3-64C When the diameter of cylinder is very small compared to its length, it can be treated
as an indefinitely long cylinder. Cylindrical rods can also be treated as being infinitely long …

3-44C Thermal contact resistance can be minimized by (1) applying a thermally conducting
liquid on the surfaces before they are pressed against each other,(2) by replacing the air at …

3-1C (a) If the lateral surfaces of the rod are insulated, the heat transfer surface area of the
cylindrical rod is the bottom or the top surface area of the rod, 4/2 D As π=.(b) If the top and …
