ME-894 Advanced Refrigeration and Air-conditioning

Campus	College of E&ME
Programs	PG
Session	Fall Semester 2016
Course Title	Advanced Refrigeration and Air-conditioning
Course Code	ME-894
Credit Hours	3
Pre-Requisutes	Thermodynamics, Heat Transfer
Course Objectives	Refrigeration and Air conditioning is the crucial of all mechanical engineering subjects because it is related to all fields of life. The fluid flow and work transfer equations of fluids is well applied in this subject and it is the key subject for mechanical engineers.The course is the further extension of the fundamental knowledge gained in the undergraduate courses of Refrigeration and Air-conditioning, heat transfer and thermodynamics. Students will learn to design and implement refrigeration and air conditioning systems using standards. In addition to the study of various basic refrigeration cycles and air-conditioning systems, some of the advanced and complex refrigeration cycles are made a part of this advanced course. Detailed thermal analysis and design calculations, technical and operating procedures of key components of refrigeration and air conditioning machines are also included.
Detail Content	Review of fundamental concepts of refrigeration and air conditioning, Simple and multi-pressure vapor compression refrigeration Vapor absorption refrigeration systems Low temperature refrigeration (cryogenics) Design and analysis of refrigeration components: Compressors Expansion devices Condensers and evaporators Steam ejector and thermoelectric refrigeration systems Air conditioning systems and equipments Load estimation Psychrometric analysis of the air conditioning systems Fans and air distribution devices Piping and duct design Course Outcome To describe the working principles of various methods to produce low temperatures To clearly explain and express various types of refrigeration and air-conditioning systems To analyze and perform design calculations for vapor compression and vapor absorption refrigeration systems for different refrigerants To enumerate salient features, types, selection criteria of components of refrigeration systems (e.g. compressors, expansion devices, condensers and evaporators etc. ) and also to perform design calculation based on key design variable To define and estimate psychrometric properties and to represent psychrometric processes on psychrometric chart To perform complete psychrometric analysis of the air-conditioning system To be able to perform heating and cooling load calculation of a room/building To apply Bernoulli equation and frictional charts/equations to air conditioning duct to estimate various pressure heads, pressure loss and fan power input To design air conditioning ducts using using velocity method, equal friction method, or static regain method
