Steam jet refrigeration , mini project

AI Thread Summary
A group of mechanical engineering students in India is considering a mini project on a steam jet refrigeration system, aiming to provide air conditioning and lower water temperatures. They are unsure about the project's feasibility, particularly regarding the design and cost of thermocompressors, as well as the achievable pressure ranges for their system. Concerns were raised about the high costs and safety risks associated with steam systems, including strict regulations and the potential dangers of working with high-pressure steam. The discussion concluded with a consensus that steam projects may not be suitable for beginners due to the associated hazards. Ultimately, the group decided not to proceed with the project.

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

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
