Vapor Compression Refrigeration System uses mechanical energy to compress a refrigerant, whereas Vapor Absorption Refrigeration System uses heat energy to absorb a refrigerant.
Vapor Compression Refrigeration System vs. Vapor Absorption Refrigeration System

Key Differences

In a Vapor Compression Refrigeration System, mechanical energy drives a compressor to increase the pressure of the refrigerant, leading to its condensation and release of heat. In contrast, a Vapor Absorption Refrigeration System uses heat energy, often from waste heat or solar energy, to cause the absorption of the refrigerant into a liquid solution, facilitating cooling.

The Vapor Compression Refrigeration System relies on electricity to power the compressor, making it energy-intensive but effective for a wide range of temperatures. On the other hand, the Vapor Absorption Refrigeration System is less energy-intensive as it can utilize low-grade heat sources but is generally less efficient in performance.
