Project Summary

Our project title is "The fabrication of steam ejector test bench" and in this time period of the project. We have to provide and fabricate all the working and non working parts for the steam ejector test bench. Now, first we see what is this steam ejector test bench? Basically, an ejector replaces a compressor in the standard vapor compression refigeration system. So all the effort in making this project is for energy saving. In the ejector refrigeration system, there are two cycles, one is power cycle and the other is refrigeration cycle. In the power cycle we use a steam generator to make steam at high pressure and then this steam is passed through an ejector whuch converts the pressure into velocity. The ejector has two inlets, primary and secondary. Secondary inlet is very near to primary inlet. so, when at the primay inlet, pressurized steam is converted into velocity at the exit of primary inlet, it creates a negative pressure and this negative pressure works as a suction process to draw fluid from the secondary inlet which is the fluid from the refrigeration cycle. The components we are needed to run this setup are steam generator, ejector, condenser, evaporator, pump. expansion valve and the remaining setup including temperature, pressure and flow sensors. Very much important task in this project is to fabricate ejector with proper dimensions as it is the key component of the setup. So, the components we are going to use in this project will be worthy as it is an industrial level project.

Project Objectives

Our project has many important objectives which include;

1. In our countary, this is the least researched on  project in Thermofluids field. So, we are trying to go with this to make it feasible for our country.
2. As ejector is going to replace the compressor in the refrigeration cycle, so one of the main objective is Energy Saving which is at present, the most working era.
3. We are going to use steam instead of other refrigerants which can inturn reduce the threat of Global Warming and Green House effects.
4. Another important objective of this project is that we can use it in those industries where there is waste heat. So utilizing the waste heat is a very plus point for this project. We can use waste heat of the IC Engines also if it is used in vehicles. 

Project Implementation Method

Main working component of the project is Boiler, So our first priority will be to bring a boiler according to our requirements as we may need a pressure upto 5 or 6 bar. Next thing is to fabricate the ejector according to proper dimensions. The thing to take serious is that in ejector, there are very small dimension like the smallest diameter is 2.5 mm. So, in fabricating the ejector, pricion and accuracy will be very much under consideration. After these two key components, we will arreange condenser, evaporator, expansion valve, pump, sensors and the setup stand along with pipes and fittings. After setting all the components upto requirements, we will do the testing of project alongwith the ansys simulations to compare the experimental and software results.

Benefits of the Project

This project is very beneficial with respect to both the industry and environment as;

1. It will replace compressor in the refrigeration cycle and only moving part will be a pump whose energy consumption is very less as compared to compressor. So energy saving is the main benefit of this project.
2. The refrigerants we use in conventional refrigeration systems are very hazardous for environment and they are going to be replaced with water. So, with respect to environment, this project is very beneficial.
3. The waste heat of the industries can be utilized in this project. 
4. And at last, by God Will, we are going to run this project and leaving a key era to explore for the new engineers that they can have interest in this project and they should take this project to the next level.

Technical Details of Final Deliverable

1. We will be working at high pressures like 2 to 6 bars, So our components must withhold these conditions.
2. Another important thing in the designing parameters is the Entrainment Ratio of ejector which is, ratio of fluid coming from both primary and secondary inlets. Higher the entrainment ratio will be, more efficient the project will be. So, we will do our best to set parameters so that we can get maximum entrainment ratio.
3. There will be a condenser and an evaporator in our project, the more they will exchange heat, more performance of the project we will have, So the working of these two components will be considered very much.
