1. Preventative Heatstroke Cooling Shelter: ASHRAE Design Competition Andres Gomez Errick Santana Orangel Velazquez EML 4551 Ethics and Design Project Organization FIU Department of Mechanical Engineering Miami, FL

2. Problem Statement Heatstroke Symptoms Treatments Statistics 675 people die due to heat exhaustion yearly Average temperature School occurrences

3. Preventative Measurements Apparatuses: Kestrel Heat Stress Meter Cooling Vest and accessories Cooling Centers around the country

4. Project Objective Build portable and reusable cooling shelter Shelter design must have two separate modes for cooling For dry hot climate For humid hot climate Achieve desired temperature in 10 minutes and maintain for an hour All cooling must be self generated

5. Project Objective Cost Efficiency Low power usage Low cost materials Reusable water Environmental Impact Water waste keep to minimum Materials

6. Design Alternative 1 Advantages Easily collapsible Conical design creating vortex of air flow. Lightweight Disadvantages Restricts airflow at top Needs support to stand

7. Design Alternative 2 Advantage Sturdy Design Easier to setup Portable Obstacles Difficult to install mist water flow system Bulky in storage

8. Proposed Design Advantage Lightweight <150lbs Easy hanging setup Portable Creates vortex air flow Obstacles Creating solid 3-pt buckle connection Securing mist water flow system Diameter = 3ft Height = 5.5 ft

9. Global Design Integration The shelter requires power from an outlet Two different voltages and frequencies around the world Device will accommodate to all global standards

10. Global Design Integration There are 15 different types of electrical outlet plugs around the world The cooling shelter will accommodate to all type of power outlets

11. Global Design Integration Shelter composed of various components (fan, motor, mist water flow system, cooling Peltier plates) All parts can be individually replaced Simple end user replacement of all major components Use of cooling equipment is immediately ready for easy use when connected

12. Engineering Standards The ASHRAE Handbook (American Society of Heating, Refrigerating and Air-Conditioning Engineers) HVAC (Heating, ventilation and cooling) standards for components, and mechanism ASHRAE 55 Establishes requirements to be meet when creating thermal indoor environments for human use. OSHA (Occupational Safety and Health Administration) Heat Index Guide Provides information and standards of safe temperatures for individuals working outside. Tables and charts to determine the likelihood of suffering a heat stroke based on outside conditions

13. Conclusion Three alternate designs were developed A final proposed design was completed All working components of the cooling shelter had been determined (Fan, Mist water flow system, Fabric, Hanging strap system )

14. Future Work Flow Analysis and simulation of cooling shelter Calculate cooling Peltier plate efficiency and reliability Evaluate main cooling fan for optimal speed and dependability Analysis and simulation of fabric’s reflective performance under the sun Final build and testing of cooling shelter under various different environments
