Designing of Cascade Cooler

In summary, the conversation is about a group of final year mechanical engineering students in India seeking help with designing a Cascade Cooler for their college project. The cooler is used in an Air separation plant and utilizes dry N2 to cool water and then the air flowing through a coil inside the tank. The students are looking for help with the design procedure for the tank, coils, and flanges. They were directed to a forum for engineers called eng-tips, but it is not helpful for student questions.

Hi Experts :smile:

Finally I think I found the correct space to assist me from experts.

I need urgent help from u pp about the Cascade Cooler.

We r doing a project in our college as final year BE, Mechanical students in India. We have choosen to Design the Cascade cooler which is used in Air separation (Oxygen/Nitrogen) Plant before a Chilling Unit.

This cascade cooler uses dry N2 to cool the water which is already inside the tank then this cooled water cools the air which flowing through the coil placed inside the tank. See below:

This is a Cascade Cooler tank

in actual use

N2 comes from top left yellow pipe and after entering second side taken out from right yallow pipe.

Now what we want is its design procedure
1. Design of tank (h,t,w,b)
2. Design of coils (D outer, D inside, L, No of turns)
3. Design of Flanges (Not imp, but 1 and 2 r imp)

Pls if know something abt it pls give link here or post it here

Thx.

eng-tips doesn't like student questions from what I've seen
 

1. What is a cascade cooler?

A cascade cooler is a type of cooling system that uses multiple stages of refrigeration to achieve lower temperatures. It consists of two or more refrigeration cycles that are interconnected, with the coldest cycle cooling the warmer one. This allows for lower temperatures to be reached than would be possible with a single-stage cooler.

2. How does a cascade cooler work?

A cascade cooler works by using multiple refrigeration cycles, each with its own compressor, condenser, and evaporator. The first stage cools the second stage, and the second stage cools the third stage, and so on. This allows for a continuous cooling process, with each stage reaching lower temperatures than the previous one.

3. What are the advantages of using a cascade cooler?

There are several advantages to using a cascade cooler. Firstly, it can achieve lower temperatures than a single-stage cooler. Secondly, it allows for better control over temperature fluctuations as each stage can be adjusted independently. Lastly, it is more energy-efficient compared to other cooling methods as it uses the cooling power of one stage to help cool the others.

4. What are the key components of a cascade cooler?

The key components of a cascade cooler include compressors, condensers, evaporators, and heat exchangers. The compressors are responsible for compressing the refrigerant and moving it through the system. The condensers remove heat from the refrigerant, and the evaporators absorb heat from the surrounding environment. The heat exchangers transfer heat between the different stages of the cascade cooler.

5. What are some common applications of cascade coolers?

Cascade coolers are commonly used in industrial and scientific settings, such as in laboratories, medical facilities, and semiconductor manufacturing. They are also used in refrigeration systems for food and beverage storage, as well as in air conditioning units for large buildings. Cascade coolers are also used in cryogenic applications, such as in the production of liquid nitrogen and oxygen.
