This document compares and contrasts the simple vapor compression refrigeration cycle and the simple vapor absorption refrigeration cycle. It outlines the main components of each cycle - compressor, condenser, expansion valve, evaporator for the vapor compression cycle and absorber, generator, pump, condenser, expansion valve, evaporator for the vapor absorption cycle. It describes the main functions of each component and concludes by stating that the vapor compression cycle is more efficient and has a higher COP but requires electricity, while the vapor absorption cycle is less efficient and complex but uses heat such as steam instead of electricity.
Difference Between Simple Vapour Compression cycle and simple vapour absorption cycle
- 1. Simple Refrigeration Cycle Presented By – Mr. Prasad Ghare
- 2. Simple Vapour Absorption CycleSimple Vapour Compression Cycle
- 3. Components used in both VCR & VAR System Vapour Compression Refrigerant Cycle 1. Compressor 2. Condenser 3. Expansion Valve 4. Evaporator Vapour Absorption Refrigerant Cycle 1. Absorber 2. Generator 3. Pump 4. Condenser 5. Expansion Valve 6. Evaporator
- 4. Main Functions of Components in VCR Cycle 1.Compressor Create flow of refrigerant Create pressure difference 2.Condensor Extract heat from refrigerant and transfer to surrounding Convert vapour refrigerant to liquid refrigerant 3.Expansion Valve/Device Reduce the pressure of refrigerant 4.Evaporator Absorb the heat from room or space which we want to make cool Convert liquid refrigerant to vapour refrigerant
- 5. Main Functions of Components in simple VAR Cycle 1.Condensor 2. Expansion Valve and 3. Evaporator (These 3’s function is same as in VCR cycle) 4.Absorber Suck low pressure refrigerant from evaporator 5.Generator To provide high pressure refrigerant to condensor 6.Pump Pass refrigerant Absorber to Generator
- 6. Simple Vapour Absorption Cycle 1. More Efficient 2. COP is Greater than VAR cycle 3. Compact 4. Electricity are used 5. Compressor is used 1. Less Efficient 2. COP is less than VAR cycle 3. Complex as compare to VCR cycle 4. Steam/Hot water etc. are used 5. Compressor is replaced by Absorber and Generator Vapour Compression Cycle
