Hi. I did a concept about: Phase change materials (PCM’s) take advantage of a material’s high heat of fusion in order to store incredible amounts of energy with little to no temperature change. Typical energy storage is classified as sensible heat storage, because the heat source/sink changes temperature as heat is added or removed. PCM’s are classified as latent heat storage because the PCM’s don’t change temperature as heat is added or removed, but rather change phase, typically from solid to liquid and vice versa. Melink believes that there is untapped potential with PCM’s when it comes to the area of heating and cooling, particularly in the Geothermal industry. Heating and cooling is one of the largest drains on the global energy grid, and is an area ripe for game-changing innovation to create more energy-efficient systems resulting in a more sustainable world. Description of project or problem Heating and Cooling systems require incredible amounts of electricity to run and are largely considered an operational necessity. Typically, these systems are inefficient and rely on large amounts of fossil-fueled electricity. Melink would like the project team to research, design and analyze a more sustainable, innovative geothermal heating and cooling system utilizing phase change materials. The project will involve researching the properties of PCM’s and becoming familiar with their best practices. The next steps will require outside-the- box thinking as the team will be tasked with brainstorming innovative solutions to an age-old problem. After the team identifies their top conceptual design, a feasibility analysis will be performed and a business plan will be created to show how this innovative technology can be mainstreamed. my concept is: putting microencapsulations PCM's on the ground loup of the HVAC system just like the uploaded picture "my concept pic" I need you to find some answers for this project by using online sources: Will the microencapsulations PCM's be crushed? (so to find what is the best shell and PCM for that and shows why they are the best?)(you may do matrix to compare between the materials) Will antifreeze corrode the capsule ?( you may find out their freezing point)( Possible reduction in the size of the ground loop? Find increased pump work required due to microencapsulation. Calculated energy savings due to increased heat storage.
