Difference between Vapour Compression and Vapour Absorption Systems with Comparison Chart
Summary:
The Major Difference between Vapour Compression and Vapour Absorption Systems is that there are some aspects in which the vapor absorption refrigeration system is different from that of vapor compression. The principle is the same for the two systems. But there are differences between mechanical parts and power consumption etc.
Comparison Chart
| Particulars | Vapour Compression Systems | Vapour Absorption Systems |
|---|---|---|
| Working method | Refrigerant vapor is compressed | Refrigerant is absorbed and heated |
| Type of the energy Supplied | Mechanical work supply to the compressor | Heat energy supply to the generator |
| Input work required | More compression work is required | Less mechanical energy is required to run a pump. |
| COP | High (Approx. 3) | Low (Approx. 0.6) |
| Capacity | Limited up to 1000 tons for a single compressor. | It may be above 1000 tons |
| Noise | More | Quiet operation |
| Leakage | More leakage due to high pressure | Almost there is no Leakage |
| Operating cost | High because of compressor consumes more work | Less because of less heat energy is required |
| Suitable refrigerant | R-12 | Ammonia |
