After the … The ability of certain liquids to absorb enormous quantities of heat as they vaporize is the basis of this system. The working of Vapor Compression Refrigeration System can be completed under 4 processes and are as follows. It can be operated by any type of prime mover/system such as electrical motors, petrol/diesel engine, etc. The plate evaporators are used in domestic fridges and freezers etc. The liquid refrigerant coming out from condenser through expansion valve is passed through coiled tube and gets evaporated and the vapor thus formed in evaporator is sucked by the compressor. The components of the Vapor Compression Refrigeration cycle are Compressor, Condenser, Receiver, Expansion Valve, and Evaporator. Vapor compression refrigeration system consists of the following important components: 1. Thus, the evaporator coils are always dry. All joints are completely welded, such that there is no leakage of refrigerants. The vapour at low pressure and low temperature enters the compressor from the evaporator where it is compressed to high pressure and high temperature. Vapour compression refrigeration is the primary method to provide mechanical cooling. The low temperature, low pressure vapour at state B is compressed by the compressor. Privacy Policy 9. 5/25/2017 1 Ch 3: Components of Vapor Compression Refrigeration System Md Rahmatuzzaman Rana Assistant Professor, Dept of FET, SUST Objectives • To let students become familiar with the main components (evaporator, compressor, condenser, valve) of a refrigeration system • To investigate the environmental effects of … The model is then used to determine the refrigerant charge in This is used for low- capacity unit, such as domestic fridges, window air conditioner, etc. It is used in domestic refrigeration for keeping the food. This paper is to study the thermal analysis of vapor compression refrigeration system using R134a in primary circuit and Al 2 O3-Water based nano-fluids in secondary circuit. Key Components of Mechanical Compression Chillers: Evaporator: Chillers produce chilled water in the evaporator where the cold refrigerant flows over the evaporator tube bundle. This is w… The vapor-compression cycle is used in most household refrigerators as well as in light commercial, commercial, and industrial refrigeration systems. This is used in small hermetic unit such as domestic refrigerator, fridges, and window air conditioners. Next the refrigerant flows through the condenser, where it condenses from vapor form to liquid form, giving off heat in the process. Gandhinagar Institute Of Technology Subject – Applied Thermal and Hydraulic Engineering(2140907) Branch – Electrical Topic – Refrigeration - vapour compression refrigeration system 2. The device is incorporated in between receiver and the evaporator. In this video,I have explained Vapour Compression Refrigeration System. He also holds the position of Assistant Professor at Sreenidhi Institute of Science and Technology. In the process of being compressed the cool, gaseous refrigerant is turned to a very hot and high-pressure vapor. 6.15. Watch Queue Queue The power utilized in vapour com­pression system is high grade energy i.e., electric power for running the compressor motor. The vapour at low temperature and low pressure enter the compressor where it is compressed isentropically and subsequently, its temperature and pressure considerably increase. The condenser consists of copper or steel coil in which high-pressure and high-temperature refrigerant vapor is condensed. Here in this platform, you get the subject-oriented notes, latest jobs, trends, and news at your fingertips. Components of Vapor Compression Refrigeration System 1. Hence these systems are also called as heat operated or thermal energy driven systems. Compressor. 2. 1/2 to 1/3 of refrigerating effect. 2. In this system a working fluid known as refrigerant (such as Freon-12, Freon-22, NH3, SO2, CO2, etc.) To learn more about vapor compression refrigeration systems, and how to find the right parts for your HVAC or refrigeration system, contact Compressors Unlimited today. The Vapor Compression Refrigeration Cycle involves four components: compressor, condenser, expansion valve/throttle valve and evaporator. From the receiver tank, it passes through the expansion valve, where it is throttled down to low pressure and temperature.
