Problems with specifying ∆Tmin in design of processes with heat exchangers
نویسندگان
چکیده
We show in this paper that the common method of specifying ∆Tmin in design of heat exchanger systems may lead to wrong decisions and should be used with care. Although specifying ∆Tmin is reasonable for heat exchanger networks synthesis with given stream data, it should not generally be used for obtaining optimal design data and especially not stream data (temperatures). An alternative simple TAC method is suggested and compared with the ∆Tmin-method on three vapour compression (refrigeration) cycle case studies.

In many industrial processes, heat exchangers play the important role of the cooling function. The effective heat transfer rate in a specific process strongly depends on the heat exchanger design. The most popular type of heat exchangers commonly used in the automotive industry, is called "radiator". In engines, radiators play the important role of the cooling process. The present study is de...

Heat exchangers are one of the most important devices of mechanical systems in modernsociety. Most industrial processes involve the transfer of heat and more often they requirethe heat transfer process to be controlled. A heat exchanger is the heat exchanged betweentwo media, one being cold and the other being hot. There are different types of heatexchanger, but the type which is widely used in...

At many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. In such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. In this research work a n...
