Refrigeration System (vapoor Compression Cycle) PPT Presentation Summary : mata pelajaran kompresormateri : refrigeration system. The Basics Essentially, a vapor-compression refrigeration system is a system that uses liquid refrigerant in a closed system which circulates the refrigerant through four stages in which it is alternately compressed and expanded, changing it from liquid to vapor. Vapor-compression refrigeration, in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air-conditioning of buildings and automobiles.

It requires smaller evaporator.-Advantages and Disadvantages of Air Refrigeration System - Mechanism And Working Of A Vapour Compression Refrigeration System - Comparison Between Heat Engine, Refrigerator, And Heat Pump If output of compressor is superheated vapor, 11 12. The refrigerant enters the compressor as saturated vapor at 140 kPa and is compressed to 800 kPa. Figure 1 depicts a typical, single-stage vapor-compression system. 36.20.

It may be recalled that in the compression system the vapour was compressed by undergoing a great change in volume during the compression process. Topic – Refrigeration - vapour compression refrigeration system. These are the evaporator, condenser, compressor and the expansion valve. Working Fluid for Vapor Absorption Refrigeration System (VARS) Some Experimental Results for Different Fluid Various Designs of VARS Cost Analysis Conclusions 2.INTRODUCTION The basic aim of this presentation is to provide basic background and review existing literatures on VARS. The … Types of Refrigeration • Vapour Compression Refrigeration (VCR): uses mechanical energy • Vapour Absorption Re frigeration (VAR): uses thermal energy Vapour Compression Refrigeration • Highly compressed flu ids tend to get colder when allowed to expand • If pressure high enough It is also used in domestic and commercial refrigerators, large-scale warehouses for chilled or frozen storage of foods and meats, refrigerated trucks and railroad cars, and a host of other … Condenser-Removes heat from refrigerant by providing a medium at a lower temperature to which the heat may flow to be dissipated. Latent heat involved in Phase change ensures high value of heat removal, while air refrigeration system has sensible heat only.

Ideal and Actual Vapor-Compression Refrigeration Cycles 16 11–15 Consider a 300 kJ/min refrigeration system that operates on an ideal vapor-compression refrigeration cycle with refrigerant-134a as the working fluid. drs. 35 Refrigeration Equipment Figure 3.1 : Cylinder and Piston Mechanism and P-V Diagram of a Reciprocating Compressor Where D is the bore or diameter and L is the stroke, i.e. Working Fluid for Vapor Absorption Refrigeration System (VARS) Some Experimental Results for Different Fluid Various Designs of VARS Cost Analysis Conclusions 2.INTRODUCTION The basic aim of this presentation is to provide basic background and review existing literatures on VARS. VARS is also belongs to class of vapor cycle is similar to the VCRS. • Also, for some applications the simple vapor-compression refrigeration cycle is inadequate and needs to be modified. Seminar presentation on Vapour Compression Refrigeration, No public clipboards found for this slide, Simple Vapour Compression Refrigeration System. Download Powerpoint; Fig. evaluating property data at principal states of the systems. SOLUTION: Flownex was used to simulate a vapour compression refrigeration system using R22 as refrigerant. 4 . 3 Comparison of mass flow rate for R12 and R134a Solar Refrigeration : Current Status and Future Trends 6.

If you continue browsing the site, you agree to the use of cookies on this website. The most widely used system utilizes a vapor compression machine powered ne via pulley and belt or by an APU (Auxiliary Power Unit). As such, the refrigerant is slightly superheated at the outlet of the evaporator. Prof. @ Dr. Akhilesh Das Gupta Institute of Technology and Management, New Delhi. The resulting vapor is compressed to a higher pressure (1 → 2). sources of this heat: Heat absorbed by the evaporator. VARS is also belongs to class of vapor cycle is similar to the VCRS. Construction: The vapour absorption system consists of a condenser, an expansion valve and an evaporator. • To get acquainted with a vapor-compression refrigeration system • To be able to use pressure-enthalpy diagrams and tables • To determine the C.O.P.
