Heat Transmission Of Thermal Energy - 3198 Words

Running Head: Report Heat transmission Heat transmission is the process through which heat is transferred in swap of thermal energy that exists between the physical systems, depending on the pressure and temperature by dissipating heat. The essential modes of transferring the heat are convection, conduction or diffusion and radiation. Heat is transferred from region of high temperature to low temperature region. The various modes of heat transfer are as follows: Conduction Conduction mode of heat transfer is the process in which transfer of energy is taken place between the objects that are having the physical existence. In this process heat is spreads through a matter when faster molecules and atoms run over with the slower†¦show more content†¦In radiation heat can be transferred through empty breathing space with the help of thermal radiation. Building are designed and built with the purpose to provide shelter and comfort zone to the living of human being. Buildings are also a major source to rescue from the external temperature, various unstable weather conditions and environment. In accordance with the natural rule the human beings release well defined amount of heat in order to feel comfortable. The reduction of heat will maintain the normal body temperature of human being. If the heat is not released the person will not maintain its normal body temperature and feel either cold or hot. Heat is released to maintain the body temperature and to maintain that normality heat must be released into the external environment. Heat will help to maintain the temperature if required amount of heat is not released it would create a warmer temperature and resultant a suffocation and if too much heat is released temperature could become cooler. Heat can be released through various building elements such as doors, floors, windows or bu ilding sealing. Heat transferred due to the certain loads, these loads are also known as the fabric heat gain or loss. Generally heat is transferred from high temperature region to low temperature region. Heat transmission through building, wall, and floor or of any construction can be expressed in the form of an equation. The equation is as follows. Ht?= U A
