2. Problem Statement of Project
To create and design an operating Oceanic Thermal Energy Conversion model that employs a closed Rankine Cycle that utilizes R22 as the working fluid to illustrate the viability of OTEC power production.

3. OTEC Model Organization
Condenser cools vapor into liquid using water from a cold tank pumped through it (forced convection)
Vapor turns turbine and power is produced with a generator
Cycle begins again
Working fluid is pumped into evaporator
Evaporator turns the working fluid into vapor using water from a heated tank that is pumped through it (forced convection)

4. Pro-E Model Changes
This was our Pro-E model based on our project needs before we started ordering parts
When we began ordering parts, we realized that we were going to need to greatly change the Pro-E model of our system
We were able to greatly decrease the overall size of the system and fit it onto a single movable cart.

5. Design Differences:
Our new design fits on a movable cart with dimensions: 60” wide x 30” deep x 32” tall
Our heat exchangers are much smaller than previously expected with dimensions of 4” wide x 5” deep x 20” tall
We changed our tank design which is now a cylindrical tank design with a pre-plumbed hole that we connect to the circulation pumps

7. Progress this Semester
We have contacted Mike Coleman at the CAPS building to acquire our security passes and a working area at the CAPS building.
We have began correspondence with Dr. Greska at the FMRL to try and source a turbine that is sized for our application.
Ordered our initial list of parts so that we can begin construction of the system.

8. Ordered Parts
The following parts list will allow us to begin building the circulation systems for the cooling and heating systems.
We will order the condenser and evaporator, that were created specifically for our application, directly from Alfa Laval through Dr. Dave Cartes beginning next week when he returns back to FSU.
The heat exchangers will not factor into our budget set aside by the College of Engineering

9. Future Plans
We need to contact a local HVAC company in order to charge our system with R22 to our specified pressure.
Work with our contacts at Lockheed Martin to expand our budget so that we can move ahead with our second order or parts.
Determine which turbine we will be using so that we can order it and begin assembly and testing.
