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. 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.

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

Pro-E Model Changes This was our Pro-E model based on our project needs before we started ordering parts 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 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.

Design Differences: Our new design fits on a movable cart with dimensions: 60” wide x 30” deep x 32” tall 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 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 We changed our tank design which is now a cylindrical tank design with a pre- plumbed hole that we connect to the circulation pumps

New Pro-E Schematic

Progress this Semester We have contacted Mr. Coleman at the CAPS building to acquire our security passes and a working area at the CAPS building.

Ordered Parts The following parts list will allow us to begin building the circulation systems for the cooling and heating systems. 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.

These parts will not factor into our budget set aside by the College of Engineering These parts will not factor into our budget set aside by the College of Engineering

Future Part Orders We need to contact a local HVAC company in order to charge our system with R22 to our specified pressure. We need to contact a local HVAC company in order to charge our system with R22 to our specified pressure.
