The paper addresses the problem of finding appropriate solutions for heat recovery from thermal engines used in containerized electrical generators. The use of special design heat exchangers using corrugated pipes in tight geometries was studied in comparison with classical pipe heat exchangers. The heat recovery targeted both flue gases and engine block cooling. The flue gases — water heat exchanger...
The Heat exchanger is a significant system that are used in process, manufacturing and production industries. In present days the system developed should be effective and work in the most efficient way and must be energy saving. This enables us to concentrate on the field of heat exchangers where the energy processing happens. The consistent monitoring and control of temperature improves the performance...
Remote labs that enable students to conduct real-world experiments at a distance using a computer and Web-based tools can be the only realistic method of performing practical experiments in the context of distance learning.
A shell-and-double concentric-tube heat exchanger is a new invention in heat transfer devices that is used for transfer of internal thermal energy between three fluids at different temperatures. The structure of the heat exchanger for this project is made of a shell which encloses sixty-six double concentric tubes. There are three inlets and three outlets for all the fluids. The typical shell-and-tube...
According to the basic formula of central heating system, the running adjustment formular is derived concerning it. On the basis of the formula, the running adjustment curve is obtained by using origin when adopting the different ways of regulation on both sides of heat exchanger. Finally with the outdoor temperature, it is concluded that the adjusting method of the variable flow and temperature of...
This paper firstly introduces the principles of Refrigerant Phase-Change Stirling-Cycle solar power towers This heat engines use solar reservoire. When the refrigerant in an engine cylinder absorbs heat from high-temperature heat sources, refrigerant is transformed from liquid to gas and the volume of the refrigerant expands to drive the piston apply work. When the refrigerant releases heat to low-temperature...

This paper is to test the performance of Heat Pipe Fresh Air Ventilation, the core component of the Heat Pipe Fresh Air Ventilation this article designed is new energy-saving exchanger, namely the heat pipe heat exchanger, so the main tasks of measuring shift to a measurement of the heat pipe heat exchanger performance. To validate the design of a new heat exchanger can achieve the desired heat transfer...
To the basis of first law of thermodynamics, mainly applicable to engineering calculations; to the basis of the second law of thermodynamics - entropy analysis method, can be used to apply to theoretical analysis and engineering calculations. In this paper, a single performance valuation and entropy analysis for heat recovery equipment have been used, which is to make performance evaluation of heat...
The purpose of the present activity was investigation of heat transfer in heat exchanger (condensator) of air conditioning systems. For this purpose the two dimensional model of calculation of heat transfer in the heat exchanger (cross-precise compact plate-ribbed) is designed. As a result of calculations the two dimensional fields of temperatures of a heat-transport surface received, ground which...
