Problem Statement of ProjectProblem Statement of Project

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

Pro-E Model ChangesPro-E Model Changes This was our Pro-E This was our Pro-E

model based on our model based on our project needs before project needs before we started ordering we started ordering partsparts

When we began When we began ordering parts, we ordering parts, we realized that we were realized that we were going to need to going to need to greatly change the greatly change the Pro-E model of our Pro-E model of our systemsystem

We were able to We were able to greatly decrease the greatly decrease the overall size of the overall size of the system and fit it onto a system and fit it onto a single movable cart.single movable cart.

Design Differences:Design Differences:

Our new design fits on a movable cart with Our new design fits on a movable cart with dimensions: 60” wide x 30” deep x 32” talldimensions: 60” wide x 30” deep x 32” tall

Our heat exchangers are much smaller Our heat exchangers are much smaller than previously expected with dimensions than previously expected with dimensions of 4” wide x 5” deep x 20” tallof 4” wide x 5” deep x 20” tall

We changed our tank design which is now We changed our tank design which is now a cylindrical tank design with a pre-a cylindrical tank design with a pre-plumbed hole that we connect to the plumbed hole that we connect to the circulation pumpscirculation pumps
