What is simple vapour absorption refrigeration system?
Answer: A Simple Vapor absorption system consists of evaporator, absorber, generator, condenser, expansion valve, pump & reducing valve. In this system ammonia is used as refrigerant and solution is used is aqua ammonia. The released vapor is passed to condenser and weak solution to absorber through a reducing valve.
How vapour absorption refrigeration system works?
In a Vapour compression system, the compressor sucks the refrigerant from the evaporator and compresses it under high pressure. Thus the absorber and generator replace the compressor in the vapor absorption cycle. The absorber enables the refrigerant to flow by absorbing from the absorber to the 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.
What is VARS system?
Vapour Absorption Refrigeration Systems (VARS) belong to the class of vapour cycles similar to vapour compression refrigeration systems. Since these systems run on low-grade thermal energy, they are preferred when low-grade energy such as waste heat or solar energy is available.
What are the main components of vapour absorption refrigeration system?
Components in Vapour Absorption Refrigeration System:
- 1 Evaporator: The main function of the evaporator is to provide cooling to the area with which it is in contact.
- 2 Absorber: The absorber is used to absorb the refrigerant.
- 3 Pump:
- 3 Generator:
- 4 Analyzer:
- 5 Pressure Reducing Valve:
- 5 Condenser:
- 6 Expansion Valve:
What are the advantages of vapour absorption refrigeration system?
Advantages of using Vapor – Absorption Refrigeration System No moving part except pump-motor, which is comparatively smaller than compressor system. Quiet in operation, low maintenance cost. Can work only with thermal energy as an input. Can be built for huge working capacities.
What are the main components of Vapour absorption refrigeration system?
Which refrigerant is used in Vapour absorption refrigerator?
Solution(By Examveda Team) A vapour absorption refrigerator uses Aqua-ammonia as a refrigerant. In the vapor absorption system the refrigerant used is ammonia, water or lithium bromide. The refrigerant gets condensed in the condenser and it gets evaporated in the evaporator.
What are the parts of vapour absorption refrigeration system?
Which refrigerant is used in vapour absorption refrigeration?
A vapour absorption refrigerator uses Aqua-ammonia as a refrigerant. In the vapor absorption system the refrigerant used is ammonia, water or lithium bromide. The refrigerant gets condensed in the condenser and it gets evaporated in the evaporator.
What is the PPT of vapor absorption refrigeration?
The ppt contains detailed study of Vapor Absorption Refrigeration System with neat sketches and description. It is well formed as per the syllabus of GTU 1. Vapor Absorption Refrigeration System (VARS) 1 Faculty Name: Prof. Ajaypalsinh G. Barad Branch: Mechanical Semester: 6th Name of Subject: Refrigeration and Air Conditioning 2.
What is simple vapour absorption system?
4. SIMPLE VAPOUR ABSORPTION SYSTEM • Ammonia vapour from evaporator is absorbed by water in absorber. Condensation heat released is absorbed by cooling water. • After being pumped to generator, heat is supplied which gives ammonia vapour. Weak sol. sent back to absorber.
What is the working principle of refrigeration system?
• After condensation in condenser, refrigerant is throttled by expansion valve and then it evaporates in evaporator providing the refrigeration effect. 4. SIMPLE VAPOUR ABSORPTION SYSTEM • Ammonia vapour from evaporator is absorbed by water in absorber. Condensation heat released is absorbed by cooling water.
What is an absorber in a refrigeration system?
• The compressor is replaced by an absorber, a pump, a generator and a pressure reducing valve. • In this system, the vapour refrigerant from the evaporator is drawn into an absorber where it is absorbed by the weak solution of the refrigerant forming a strong solution.
