In industries now a day the control of chemical process is important craft. Mostly all the chemical process are highly nonlinear in nature this cause instability of the process. This paper deals with basic simulation studies on of the interactive thermal process. The Combination processes of Continuous stirred tank reactor (CSTR) and heat exchanger were controlled and the mathematical model was developed...
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...

In this report, we describe the design of a concentrated solar thermoelectric (TE) system which can provide both electricity and hot water. Today's thermoelectric materials have a relatively low efficiency (~6% for temperature difference across the thermoelement on the order of 300°C). However since thermoelectrics don't need their cold side to be near room temperature, (in another word, one can chose...
In the present energy crisis situation, maximization utilization of energy use is vital matter, especially an air conditioning unit which is one of the largest energy use in the home. The objectives of this paper are to: i) design and development of a portable air conditioning:-heat pump unit using helical coil heat exchanger, ii) improve the cooling performance of a portable air-conditioning heat...
