Steam jet refrigeration , mini project

Click For Summary
SUMMARY

The forum discussion centers on a mini project involving the design and fabrication of a steam jet refrigeration system, including components such as a boiler, steam nozzle, thermocompressor, flash chamber, condenser, and pump. Participants express concerns about the feasibility and safety of the project, particularly regarding the high costs and the dangers associated with steam systems. The discussion highlights the necessity of adhering to ASME regulations for boiler safety and the impracticality of using steam for beginner-level projects. Ultimately, the group decides not to proceed with the project due to these challenges.

PREREQUISITES
  • Understanding of steam jet refrigeration systems
  • Knowledge of ASME regulations for boilers and pressure vessels
  • Familiarity with thermocompressor design
  • Basic principles of thermodynamics and fluid mechanics
NEXT STEPS
  • Research the design principles of steam jet ejectors
  • Learn about the safety standards and regulations set by ASME
  • Explore alternative refrigeration systems suitable for mini projects
  • Investigate the cost analysis and budgeting for engineering projects
USEFUL FOR

Mechanical engineering students, project managers in engineering, and anyone interested in the design and safety of refrigeration systems.

im from India , in my third year of B.E. Mech degree .. course... and my group is planning to do steam jet refrigeration system...as a MINI PROJECT ( Design And Fabrication Project in the syllabus)..
the components of the project are -
1. boiler
2. steam nozzle
3. thermocompressor
4. flash chamber
5. condenser
6. pump

we know the working of the system ... and the theory is also familiar though not so thoroughly

our aim is to provide air conditioning (comfort) and to drop the temp of water by few degrees..

First question .. is that . Will this project be feasible for my level of education...
and are thermocompressors.. easy to design ... and what will be the cost for them...??

i need help... please do reply.. my refrigeration lecturer suggested the project but we doubt its feasibility..

what pressure ranges can be achievable for a small system for few degrees drop in temperature??

Sounds to me like you are designing a steam jet ejector. See the link below for help.

the project costs a lot and it needs supersonic velocities so we .. are not proceeding...
any way thanks

anytime I hear people asking about steam stuff with no practicle experience, I cringe.
power steam is deadly at best. A small leak can remove fingers, arms, legs, and peel the hide and flesh off of your body. IN MOMENTS! many gov'ts have VERY strict inspection requirements for just heat boilers, let alone power ones. I've been involved in steam locomotive restoration and operation, so have a pretty good basic knowledge of the stuff. Steam is not a good low buck, first level project for most applications. people can die, or worse

Yes, dr dodge, I agree.

Always make sure to follow the ASME (American Society of Mechanical Engineers) rules and regulations for boilers and pressure vessels.

He did say that they are not proceeding with the project.

Thanks
Matt
