Explanation: The expansion is an adiabatic throttling process in which enthalpy remains unchanged. Explanation: This is the COP of vapour refrigeration cycle.
Which component of a Vapour compression refrigeration unit is housed inside the freezer of a domestic refrigerator?
The compressor is located at the back of the refrigerator and in the bottom area. The compressor sucks the refrigerant from the evaporator and discharges it at high pressure and temperature. The compressor is driven by the electric motor and it is a major power-consuming device of the refrigerator.
What components in a compression refrigeration system maintain the pressure difference in the system?
To maintain the difference in pressure between the condenser and the evaporator caused by the compressor, an expansion valve is needed in the cycle. The expansion valve separates the high-pressure part of the system from the low-pressure part. Only a small trickle of refrigerant liquid flows through the valve.
What are the main components of the domestic refrigerators?
The main working parts of a refrigerator include: a compressor, a condenser, an evaporator, an expansion valve, and refrigerant .
How does Vapour compression cycle work?
The compressor takes in a low temperature, low pressure refrigerant vapor, and compresses it into a high temperature, high pressure vapor . ... The heat from the source boils off the refrigerant through phase change heat transfer, and the low temperature, low pressure gas enters the compressor, completing the cycle.
What are the components of refrigeration system?
- The compressor.
- The condenser.
- The expansion device.
- The evaporator.
What is the purpose of the 4 major components in the refrigeration cycle?
There are four main components to the refrigeration cycle: evaporator, compressor, condenser, and metering device/ thermal expansion valve (TXV). The main function of the refrigeration cycle is to absorb heat from indoor air and dispel it outdoors .
Which two components do the compressor function in Vapour absorption system?
The majors difference between the two systems is the method of suction and compression of refrigerant in the refrigeration cycle. In a Vapour compression system, the compressor sucks the refrigerant from the evaporator and compresses it under high pressure.
What are the commonly used refrigerants for Vapour compression chillers?
The most common include ammonia, Freon (and other chlorofluorocarbon refrigerants, aka CFCs) , and HFC-134a (a non-toxic hydrofluorocarbon). The Vapor-Compression Refrigeration Cycle is comprised of four steps.
What is Vapour compression system and Vapour absorption system?
A Vapour absorption system utilizes the low-grade form of heat energy to produce Cold . ... The compressor of the Vapour Compression Refrigeration System is replaced by the use of absorber, pump, and generator.
What is a Vapour absorption system?
Simple vapour absorption system In this system an absorber , a pump, a generator and a pressure reducing valve replace the compressor. The low pressure ammonia vapour leaving the evaporator enters the absorber where it is absorbed by the cold water in the absorber.
Is the vapor compression system a mechanical refrigeration system?
Although mechanical vapour compression is the most common design of refrigeration cycle , there are other alternatives. ... The advantage of this system is that most of the energy required to run an absorption refrigeration system can be provided in the form of heat rather than as mechanical power.
Which component is absent in vapor absorption cycle?
In Vapour Absorption Refrigeration System (VARS), the components used are Evaporator, Absorber, Pump, Generator, Condenser, Expander. In Vapour Compression Refrigeration System (VCRS), the components used are Evaporator, Compressor, Condenser and Expander. Thus generator, absorber and pump are absent in VCRS.
What is vapor compression cycle of a refrigeration system?
The Vapor Compression Refrigeration Cycle
The compression refrigeration cycle consists of circulating a liquid refrigerant through four stages of a closed system . As the refrigerant circulates through the system, it is alternately compressed and expanded, changing its state from a liquid to a vapor.
What are the main components of the high pressure side of a refrigeration system?
- low-pressure side of a refrigeration system. Consists of all the components that operate at or below evaporating pressure. ...
- high-pressure side of the refrigeration system. ...
- discharge pressure, head pressure, or evaporator by the compressor through the suction line, high-side pressure.
What components in a compression refrigeration system maintain the pressure difference in the system quizlet?
The four major components of the compression-refrigeration cycle in order are: Compressor, condenser, metering device, evaporator .
Which component of the refrigeration cycle controls the flow of refrigerant to the evaporator it also separates the high and low pressure sides of the system?
The TXV separates the high pressure and low-pressure sides of a refrigeration or air conditioning system. Liquid refrigerant enters the valve under high pressure, but its pressure is reduced when the TXV limits the amount of refrigerant entering the evaporator.
Which component of the refrigeration cycle controls the flow of refrigerant to the evaporator?
The flow of refrigerant into the evaporator is controlled by the pressure differential across the expansion device or, in the case of a thermal expansion valve , by the degree of superheat of the suction gas. Thus, the thermal expansion valve shown requires a sensor bulb located at the evaporator outlet.
What is the component directly following the condenser in a refrigeration system?
Correct answer is A: receiver . In a refrigeration system with a TXV or other type of throttling device, the component directly following the condenser would be the receiver.
What is domestic refrigeration system?
[də′mes·tik ri′frij·ə‚rād·ər] (mechanical engineering) A refrigeration system for household use which typically has a compression machine designed for continuous automatic operation and for conservation of the charges of refrigerant and oil, and is usually motor-driven and air-cooled.
What is simple Vapour compression system?
Introduction. A vapour compression refrigeration system is an improved type of air refrigeration system in which a suitable working substance, termed as refrigerant, is used. It condenses and evaporates at temperatures and pressures close to the atmospheric conditions.
Which of the following components are not used in simple Vapour absorption system?
In the vapor compression refrigeration system (VCRS), the components used are Evaporator, Compressor, Condenser, and Expander. Thus generator, absorber, and pump are absent in VCRS.
What makes a compressor an important component in the refrigeration system?
Compressor is the most important component, which is usually called the main engine in refrigeration system. The refrigerant steam is increased from low pressure to high pressure and the continuous flow and transportation of the steam is achieved by the work of the compressor.
Which component feeds liquid refrigerant into the evaporator?
This component is the metering device , also referred to as the expansion device. The metering device is responsible for feeding the proper amount of refrigerant to the evaporator coil.
