Vapour absorption cooling system for cars

Click For Summary

Discussion Overview

The discussion revolves around the feasibility and efficiency of using a vapor absorption cooling system for automobiles, specifically utilizing exhaust gases for air conditioning purposes. Participants explore the theoretical and practical implications of this approach.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether it is possible to provide cooling for automobiles using a vapor absorption compression system that utilizes exhaust gases, and inquires about the potential efficiency of such a method.
  • Another participant seeks clarification on whether the discussion pertains to air conditioning (A/C) or the engine itself.
  • A subsequent reply confirms that the focus is on A/C functioning.
  • Concerns are raised regarding the practicality of utilizing exhaust gases, with one participant suggesting that in the USA, the loss of heat in heat exchangers may outweigh the benefits of using waste heat for cooling.
  • In contrast, another participant posits that since conventional A/C systems primarily rely on shaft power while an absorption system would use waste exhaust heat, there could be potential savings worth investigating further.

Areas of Agreement / Disagreement

Participants express differing views on the practicality and efficiency of using exhaust gases for vapor absorption cooling. Some raise concerns about heat loss, while others suggest potential benefits, indicating that the discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Limitations include the dependence on specific conditions regarding heat exchanger efficiency and the definitions of terms used in the discussion. The feasibility of the proposed system may vary based on regional regulations and technological implementations.

It is for A/C functioning.

India, and Indian equivalent of EPA is not familiar to me; in the
USA you'll lose more than the "waste heat" is worth in heat exchangers that "isolate" it from the passenger compartment.
 
Since the normal AC primarily uses shaft power and an absorption system would use the waste exhaust heat, I would think there would be a savings. It's worth looking into in some more detail...
