In this article, we will study the Difference Between Vapour Compression and Vapour Absorption Refrigeration Systems in detail. We have also provided a PDF for the same. The main differences between Vapour Compression and Vapour Absorption Refrigeration Systems are Vapor compression has a high C.O.P (Coefficient of Performance) and Vapour Absorption has low C.O.P
Vapour Compression Refrigeration system
The Vapour compression refrigeration system is by far the most popular and widely used in refrigeration and air conditioning both for industrial and domestic applications. In this system, the working substance is a refrigerant like NH3, R-11, and R-12.
This Vapour Compression system mainly consists of a Refrigerator compressor, a liquid compressor, a liquid receiver, and a refrigerant control valve also called an Expansion valve and Evaporator.
Vapour Absorption Refrigeration system
A Vapour absorption system utilizes the low-grade form of heat energy to produce Cold. Whereas the VCR system needs work energy to produce cold which is a high-grade form of energy and expensive to produce. The compressor of the Vapour Compression Refrigeration System is replaced by the use of an absorber, pump, and generator.
This system consists of a condenser, expansion device, and evaporator with absorber, pump, and generator as a replacement for compressor of the Vapour Compression Refrigeration system

| The possibility of leakage of refrigerant is more. | The possibility of leakage of refrigerant is less. |
| Performance is adversely affected by part loads. | Reduced loads do not affect its performance. |
| It can not be located outside without shelter. | It can be located outside without shelter. |
| It is less bulky. | It is bulky. |
| Liquid traces in the suction line may damage the compressor. | Liquid traces in the refrigerant at the exit of the evaporator is not harmful to any component. |
| Wear and tear are high. | Wear and tear are less. |
| It has a compressor and a motor. Therefore, It is more noise in operation. | It has a pump only a moving part. hence it is quiet in operation. |
| It uses high-grade work energy. It needs electrical energy for its operation. | It uses low-grade heat energy, therefore, It can operate on exhaust from I.C. engines or Kerosene lamps or process heat. |
FAQ
What Is The Difference Between Vapour Compression And Vapour Absorption Refrigeration System?
The Key Difference between Vapour compression and vapour absorption refrigeration systems is that they have different principles. In compression systems, a compressor raises refrigerant pressure and temperature, causing it to condense in the condenser. It then passes through an expansion valve, reducing pressure and temperature, and absorbs heat in the evaporator. In absorption systems, the refrigerant vapor is absorbed by an absorbent, heated to release the vapor, and then condensed and recycled. Compression systems use a compressor, while absorption systems rely on an absorbent. Vapor compression has high C.O.P and Vapor absorption has low COP (COEFFICIENT OF PERFORMANCE)
What Is The Vapor Compression Refrigeration System?
The Vapour compression refrigeration system is by far the most popular and widely used system in refrigeration and air conditioning bot for industrial and domestic applications.
Conclusion
In conclusion, understanding the difference between Vapour Compression and Vapour Absorption systems is essential in selecting the most appropriate cooling technology for a specific application. While vapor compression systems are widely used due to their high efficiency and low cost, vapor absorption systems offer advantages in terms of energy consumption and environmental impact.
By considering the pros and cons of each system, individuals and organizations can make informed decisions and achieve optimal cooling performance. It is important to avoid plagiarism by appropriately citing any sources used in the research process.
