Thermodynamic Analysis of Heat Pipe Using Ammonia, Water and Ethanol with a View to Being Used in Refrigeration

Abstract

Heat pipe was developed by NASA for space applications, and this device can be used in simple refrigeration systems, which will have a great impact on the size of the system. Several working fluids can be used in the heat pipe along with the different available material in the designs of the pipe. In this research work several parameters of a heat pipe are observed varying the design conditions alongside the working fluid in the heat pipe which are Water, Ammonia and Ethanol analysed on software. The design conditions are kept as it would be in a commonly used refrigeration system. The capacity of the system is varied and analysis is done. The capacity can be enhanced without much change in the size. Also the temperature of working becomes more or less constant. Water turns out to be a very effective working fluid in a heat pipe with the view of refrigeration when the temperature of working increases.
