Abstract

Refrigeration system works on the second law of thermodynamics specifically on the Clausius statement which summarizes that the refrigerator is nothing but a reversed heat engine which consumes energy in the form of work to transfer heat from Low temperature body to high temperature body. Refrigeration system mainly works on Vapour Compression Refrigeration cycle (VCR), in simple VCR cycle the refrigerant after condensation enters into the region of interest after throttling i.e. from where the heat is to be removed. Greater the extent of condensation that ensures the low temperature vapour in cooling region. To enhance the performance means to enhance the cooling capacity but with adjustment of the consequences of doing so. The heat exchanger is installed between the suction line and the discharge line which transfer the heat from low temp low pressure suction line to the high temperature high pressure discharge line also known as Liquid Suction Heat Exchanger. The liquid in the discharge line gets sub cooled and the vapour gets superheated due to which the compressor works increases due to increase in specific volume. In this experimentation various parameters change. This paper identifies the ways of installing the heat exchanger and to find the best suitable way and to analyze the impacts of experimentation on various operating parameters.
