2.9.Difference between vapour compression system and vapour absorption system
Vapour compression system | Vapour absorption system |
---|---|
The system has a main parts like Compressor, condenser receiver, refrigerant control device and evaporator | The system has a main parts like generator, rectifier, condenser absorber and evaporator |
The system is noisy in operation | The system is quiet in operation |
The system has so many moving parts, so there is a possibility of wear and tear | The system has no moving parts and no possibility of wear and tear or sticking. |
Energy supplied is mechanical | Energy input is mainly heat |
Generally steel, copper tube is used to connect the parts | Steel tube is used to connect the parts |
To reduce the high pressure control devices like expansion valve, front valve, capacity tube are used | To reduce the pressure hydrogen gas is provided |
The flow of gas depends upon the compressor | The flow of gas depends upon the gravity and working of the generator |
This system is required to operate by prime movers like electric motor, diesel or petrol engine | This system is required to operate by heat energy like gas kerosene or electric heater. |
This system is more efficient and occupies more space | This system is poor efficient |
Charging of refrigerant is quite simple | Charging of refrigerant to the system is difficult |
Energy supply is low | Energy supply is high |
