Can Waste Heat from an Oven Power an Absorption Refrigerator?

AI Thread Summary
Using waste heat from a tunnel oven can effectively power an absorption refrigerator, with the LiBr-H2O system recommended as the optimal refrigerant. To implement this, it's essential to ensure the heat source reaches a minimum temperature to maintain system efficiency. The Carnot efficiency formula provides a framework for understanding the temperature requirements, with T1 representing the heat source temperature. Proper integration of the refrigerant into the system is crucial for effective operation. Utilizing waste heat not only enhances energy efficiency but also reduces operational costs.

Hello people I need your help.

I am kind new to refrigeration and I want to design one. I have a waste exhaust heat from the Exhaust of the tunnel oven that I have designed. Now I want to use that waste heat as the heat source for the Absorption refrigerator.

Q1: what's the best solution I can use as a refrigerant?

Q2: how can I put that solution into the system?

Thank you a lot.

For absorption refrigerator, you can use LiBr-H2O system.
 
Thank you very much. What is minimum temperature that I should apply as a heat source to make the system work?
 
Carnot Efficiency of absorption cycle = ((T1-T2)/T1) * (T4/(T3-T4))
T1 = temperature of heat source
T4 = temperature of refrigerated space
T2 = T3 = ambient temperature
All values are in kelvin

LiBr-H2O system is the best.
 
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter.
