Reusing lost energy from Compressed air

In summary, heat is not typically trapped and reused during the expansion process of air due to the logistical challenges of implementing an additional set of pipes to carry the heat. However, alternative uses for the heat, such as heating water, may provide beneficial outcomes.

Why is Heat not normally trapped when compressing Air, and reused again in the expansion process of the same air?

Welcome to PF!

It would be hard to reuse it in the expansion in most cases I can think of -- you'd need an extra set of pipes going to each usage point in order to carry the heat. That would be cumbersome for the amount of heat that can be recovered.

If you're lucky, you may be able to find other uses for that heat, such as heating water.

Ok Russ, thanks for that...just tell me, if Heat was used for expansion, how might it be configured to offer the best outcomes?
 

1. How can compressed air be used as a source of energy?

Compressed air can be used as a source of energy by utilizing an air motor or turbine. These devices convert the stored energy in compressed air into mechanical energy, which can then be used to power various applications.

2. What are the benefits of reusing lost energy from compressed air?

Reusing lost energy from compressed air can lead to increased energy efficiency and cost savings. It also reduces the environmental impact of energy production and consumption.

3. How is the lost energy from compressed air captured and reused?

The lost energy from compressed air is typically captured through a heat exchanger or a recovery system. The captured energy can then be used to power equipment or heat buildings.

4. Can all compressed air systems be retrofitted to reuse lost energy?

Not all compressed air systems can be retrofitted to reuse lost energy. It depends on the design and components of the system. It's best to consult with a professional to determine if your system is suitable for energy recovery.

5. Are there any potential downsides to reusing lost energy from compressed air?

Potential downsides of reusing lost energy from compressed air include the initial cost of installing energy recovery systems and the need for regular maintenance. Additionally, if not done properly, there is a risk of decreased efficiency and performance of the compressed air system.
