Comparison between Vapour compression & Vapour Absorption refrigeration systems S.No. Vapour Compression System Vapour Absorption System 1 This system has more wear and tear and produces more noise due to the moving parts of the compressor. Only moving part in this system is an aqua pump. Hence the quieter in operation and less wear and tear 2. Electric power is needed to drive the system Waste of exhaust steam may be used. No need of electric power 3. Capacity of the system drops rapidly with lowered evaporator pressure Capacity of the system decreases with the lowered evaporative pressure, by increasing the steam pressure in generator. 4. At partial loads performance is poor. At partial loads performance is not affected. 5. Mechanical energy is supplied through compressor Heat energy is utilised 6. Energy supplied is ¼ to ½ of the refrigerating effect Energy supplied is about one and half times the refrigerating effect

Comparison between Vapour compression & Vapour Absorption refrigeration systems S.No. Vapour Compression System Vapour Absorption System 7. Charging of the refrigerating to the system is easy Charging of refrigerant is difficult 8. Preventive measure is needed, since liquid refrigerant accumulated in the cylinder may damage to the cylinder Liquid refrigerant has no bad effect on the system.
