Thus lower the temperature of intake air, more is the energy efficiency of a compressor. As the volume of hot air reduces on cooling volumetric efficiency increases.Įvery 4 Â☌ rise in inlet air temperature results in higher energy consumption by 1 percent to achieve equivalent output. Intercoolers improve the efficiency of compressor. Cooling air down to or below its initial temperature will remove moisture down to the dew point, improving the quality of the air. Thus volume of fluid decreases which increases the volumetric capacity and decreases the work done by motor.įig 1: 2 stage compressor block diagram įig 2: Tube and shell heat exchanger įollowing are the functions of an intercooler used in compressor:Ītmospheric air contains moisture, and furthermore, the air may pick up oil vapor as it passes through some parts of the compressors. Intercoolers are generally placed in between two stages of compression as it cools down the hot fluid before sending it to second compression. Intercoolers can be placed horizontally or vertically but horizontal intercoolers are more effective thus horizontal intercoolers generally used. Intercoolers are placed after compression or between two stages of compression. The volume required of these compressed gases is very high so it is required to compress these gases efficiently. Industries often use compressed gases such as air, hydrogen, acetylene, oxygen, methane, etc. Keywordstube and shell heat exchanger, HTRI, temparature, compressor.
#Heat exchanger calculation word software
This is the software for the rating, design, and/or simulation of a wide variety of heat transfer equipment, including shell-and-tube and non-tubular exchangers, air coolers and economizers, and fired heaters. the design calculations of tube and shell heat exchanger are verified by HTRI(Heat Transfer Research Inc.) software.
#Heat exchanger calculation word verification
this article includes thermal design calculation and verification of all the process parameters which are required for proper functioning of the compressor system as a whole. Tube and shell tube and shell heat exchanger is type of heat exchanger in which two fluids which are at different temperatures are separated by solid wall. They are widely used in petroleum refineries, sewage treatment, air conditioning, power station, space heating and petrochemical plants. plate heat exchanger, Double pipe heat exchanger, shell and tube heat exchanger, condensers, evaporators and boilers are the most common types of heat exchangers.
