What is vapour compression cycle?
The Vapor Compression Refrigeration Cycle involves four components: compressor, condenser, expansion valve/throttle valve and evaporator. It is a compression process, whose aim is to raise the refrigerant pressure, as it flows from an evaporator.
What is PH and TS diagram?
The P-H and T-S diagram for the simple vapor compression refrigeration cycle is shown in the figure for vapour entering the compressor is in dry saturation condition The dry and saturated vapour entering the compressor at point 1 that vapour compresses isentropic ally from point 1 to 2 which increases the pressure from …
What type of VCR is shown in the TS diagram?
1. What type of VCR is shown in the T – s diagram? Explanation: In the shown T – s diagram the refrigerant after condensation process is cooled below the saturation temperature before expansion by throttling. This type of process is called undercooling or subcooling of the refrigerant.
What are the different components of vapour compression system and explain with neat sketch?
Answer: Vapour compression refrigeration cycle Vapour compression refrigeration cycle consist of four different processes 1) Compression 2) Condensation 3) Expansion 4) Evaporation Components and its functions 1) Compressor – The low pressure & temperature refrigerant from evaporator is drawn into compressor.
What is the Vapour compression cycle write its application?
Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), 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.
What is a P-H diagram?
A p-h diagram is a figure with a vertical axis of absolute pressure and a horizontal axis of specific enthalpy. It is an important diagram used frequently for a performance calculation of a refrigerating machine. A p-h diagram is made respectively for a specified refrigerant.
What are the four components of vapor-compression system?
3.4. 2 Vapor compression refrigerators. A detailed description of the vapor compression refrigeration is available in any basic thermodynamics textbook. All vapor compression refrigerators are made of four main components: a compressor, a condenser, an expansion orifice, and an evaporator.
What are the 4 process of refrigeration?
A refrigeration cycle has four major components: the compressor, condenser, expansion device, and evaporator. Refrigerant remains piped between these four components in the refrigerant loop.
