It carries the liquid refrigerant from the receiver and conveys it to the expansion valve. Compressor is the most important part of this system and reciprocating compressor is one of the widely used compressor of it though it varies depending on the requirements. Save my name and email in this browser for the next time I comment. It also maintains a continuous flow of the refrigerant through the system. Alternatively, a refrigeration system can be used for providing cooling in summer and heating in winter. Cycle with superheated vapor before compression, and 5. Vapor-compression refrigeration is a refrigeration system that uses a circulating liquid refrigerant to absorb and remove heat from a space that needs cooling. In a vapour compression refrigeration system, the compressor plays a key role on the power consumption and its overall performance is a result of electrical, mechanical and thermodynamic efficiencies. Cycle with under cooling or sub cooling of refrigerant. The vapor compression cycle circulates a fluid through a compressor, condenser, expansion valve, and evaporator, in order to absorb heat from a refrigerated space at a low temperature and give off heat at a higher temperature to the surroundings, thus keeping the refrigerated space cool.

Cycle with dry saturated vapor after compression, 2. 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. Many scientists have focused their attention to increase the coefficient of performance of the cycle. Oil refineries, petrochemical and chemical processing plants, and natural gas processing plants are among the many types of industrial plants that often utilize large vapor-compression refrigeration systems. During compression Stroke, the pressure and temperature increase until vapor, temperature is greater than the temperature of condenser cooling medium (air or, When the high-pressure refrigerant vapor enters the condenser heat flows from the condenser to the. Compression Process: The vapour at low temperature and low pressure enter the compressor where it is compressed isentropically and subsequently, … All the important details are covered here. From point 2 to point 3, the vapor travels through part of the condenser which removes the superheat by cooling the vapor. SOLUTION: Flownex was used to simulate a vapour compression refrigeration system using R22 as refrigerant. Currently, he is working in the sheet metal industry as a designer. Types of Condensers: • Air-Cooled • Water-Cooled. It conveys the high pressure and high-temperature refrigerant from the compressor to the condenser. Vapor-Compression Refrigeration Cycle This refrigeration cycle is approximately a Rankine cycle run in reverse. When the piston hits the point of maximum downard displacement, it compresses the refrigerant on the upstroke. It can be employed over a large range of temperatures. C.O.P. C.O.P. Main Parts Of Vapor Compression Refrigeration Cycles: Its function is to provide a heat transfer surface through which heat can pass from the refrigerated space into the vaporizing refrigerant. In this system, the working substance is a refrigerant like NH 3, R-11, R-12.. The low-pressure Vapour in the dry state is drawn from the evaporator during the suction stroke, of the compressor. In absorption refrigeration system, however, heat is directly utilized as source of energy. Modern vapor-compression systems for comfort cooling and industrial refrigeration use one of several types of compressors: reciprocating, rotary, helical (screw type), centrifugal, and scroll. After condenser the liquid refrigerant is stored in the liquid receiver until needed. The refrigerant then compressed to high pressure by the compressor and then delivered to … On this channel you can get education and knowledge for general issues and topics From the receiver it passes through an expansion valve where the pressure is reduced sufficiently to allow the vaporization of liquid at a low temperature of about -10°C. ADVERTISEMENTS: Vapour Absorption Refrigeration System (with diagram)! It acts as, a reservoir that stores the liquid refrigerant coming from the condenser and supplies it to the evaporator according to the requirement. Energy in the form of heat is removed from a low-temperature reservoir and transferred to a high-temperature reservoir. A typical refrigeration system is composed of four basic components: compressor, condenser, expansion device and evaporator. Its performance may, therefore, be estimated by calculating the efficiency of the machine which will be equal to the ratio of these two energy quantities. It gives uniform torque, therefore, the smaller flywheel may be used 5. The Vapor Compression Refrigeration Cycle involves four components: compressor, condenser, expansion valve/throttle valve and evaporator. The power utilized in vapour compression system is high grade energy i.e., electric power for running the compressor motor. At point 1 in the diagram, the circulating refrigerant enters the compressor as a saturated vapor. The intake valve closes when the refrigerant pressure inside the cylinder reaches that of the pressure in the evaporator. (a) Compression (b) Condensation (c) Expansion (d) Vaporization a) Compression, The low-pressure Vapour in the dry state is drawn from the evaporator during the suction stroke of the compressor. Each application prefers one or another due to size, noise, efficiency and pressure issues. Between points 4 and 5, the saturated liquid refrigerant passes through the expansion valve and undergoes an abrupt decrease of pressure. A refrigeration system can also be used as a heat pump, in which the useful output is the high-temperature heat rejected at the condenser. The low-pressure refrigerant vapor after expansion in the expansion valve enters the evaporator or refrigerated space where a considerable amount of heat IS absorbed by it and refrigeration is furnished. Vapour Absorption Refrigeration System - MCQs with Answers Q1. Both a steady-state and a transient simulation will be considered. The vapor-compression uses a circulating liquid refrigerant as the medium (usually R134a) which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere.The figure depicts a typical, single-stage vapor-compression system. 3. Of course, it may be preferable to utilize heat as such as it avoids undergoing through […] The first working vapor-compression refrigeration system was built in 1834 by another American who was living in the UK, Jacob Jenkins. Compression Ratio = Absolute Discharge Pressure / Absolute Suction Pressure. The Metering Device converts the High Pressure and High-Temperature Liquid from Condenser to Low Pressure and Low-Temperature Liquid-Vapor mixture, which will be fed to the Evaporator. Cycle with superheated vapor after compression, 4. The resulting refrigerant vapor returns to the compressor inlet at point 1 to complete the thermodynamic cycle. The big majority of refrigerators work based on a principle known as vapor compression. What is Condenser?

The term refrigeration means cooling a space, substance or system to lower and/or maintain its temperature below the ambient one (while the removed heat is rejected at a higher temperature). Expansion from 4-1 results in a very wet refrigerant, causing erosion of turbine blades. 10) Leakage of the refrigerant: In the absorption refrigeration system there are no (or very few) leakages of the refrigerant and the refrigerant itself is very cheap.Thus there are almost zero refrigerant recharging costs. Most of the modern refrigerators work on this cycle, in Its simplest form, there are four fundamental operations required to complete one cycle. From point 1 to point 2, the vapor is isentropically compressed (i.e., compressed at constant entropy) and exits the compressor as a superheated vapor.

After condenser the liquid refrigerant is stored in the liquid receiver until needed. Additionally, he has interested in Product Design, Animation, and Project design. Your email address will not be published. In any refrigeration process, heat is transferred from one region to another with the aid of an external agent. some circumstances, like those found in systems with water cooled condenser, where the dominant thermal resistance may be lower on refrigerant side. That process results in the adiabatic flash evaporation and auto-refrigeration of a portion of the liquid (typically, less than half of the liquid flashes). allow the vaporization of liquid at a low temperature of about -10°C. ... there will also be a rise in the temperature if the vapour is compressed.
