Steam jet refrigeration , mini project

Click For Summary

Discussion Overview

The discussion centers around the feasibility of a mini project involving a steam jet refrigeration system, including design and fabrication aspects. Participants explore the components of the system, practical considerations, and safety concerns related to working with steam technology.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses uncertainty about the feasibility of the steam jet refrigeration project for their educational level, questioning the design complexity of thermocompressors and associated costs.
  • Another participant suggests that the project resembles a steam jet ejector and provides a link for additional information.
  • A later reply indicates that the project may be too costly and requires supersonic velocities, leading to a decision not to proceed.
  • Concerns are raised about the dangers of working with steam, emphasizing the potential for severe injuries from leaks and the strict regulations governing steam systems.
  • Another participant agrees with the safety concerns and mentions the importance of adhering to ASME regulations for boilers and pressure vessels.

Areas of Agreement / Disagreement

Participants generally agree on the safety risks associated with steam systems and the complexity of the project, but there is no consensus on the feasibility of proceeding with the project.

Contextual Notes

The discussion highlights limitations in practical experience with steam systems and the potential financial implications of the project. There are also unresolved questions regarding the specific pressure ranges achievable for a small system.

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
