1 CoolPac: Cooling Device for Firefighters Team 2 BME: Jaspreet Mankoo Kerri Blanc ME: Nedim Begovac Sean Meehan Client: Createc Consulting LLC Advisor: Hans Almqvist 36A Bucks Hill Rd Southbury, CT

2 Outline Background Background Current Products Current Products Objectives Objectives Requirements Requirements Project Description Project Description Budget Budget Conclusion Conclusion

3 Createc Consulting LLC Sponsor Advisor: Hans Almqvist Sponsor Advisor: Hans Almqvist Focused on designing personal safety equipment for firefighters, industrial workers,etc Focused on designing personal safety equipment for firefighters, industrial workers,etc Main customers are local and federal government Main customers are local and federal government Successful designs include S.C.U.B.A breathing apparatus, hazmat suits, SCBA faceplates Successful designs include S.C.U.B.A breathing apparatus, hazmat suits, SCBA faceplates

4 Heat Stress Buildup of body heat generated internally or externally Buildup of body heat generated internally or externally Hastens muscular fatigue Hastens muscular fatigue Increases cardiovascular strain Increases cardiovascular strain Compromises cognitive function Compromises cognitive function Firefighters especially at risk due to high internal and external heat Firefighters especially at risk due to high internal and external heat

5 Heat Stress

6 CoolPac Prototype Designed as a sleeve to be worn under the suit Designed as a sleeve to be worn under the suit Consists of the sleeve, phase-change material (PCM), and fastening device Consists of the sleeve, phase-change material (PCM), and fastening device Human thermoregulation involves increased blood flow to extremities under stress Human thermoregulation involves increased blood flow to extremities under stress Temp. of the sleeve < temperature of the body Temp. of the sleeve < temperature of the body Heat can be absorbed by the PCM due to the shallow blood vessels Heat can be absorbed by the PCM due to the shallow blood vessels

7 CoolPac Prototype

8 Current Market KoreKooler Rehab Chair KoreKooler Rehab Chair Similar heat transfer concept Similar heat transfer concept Limited by lack of mobility Limited by lack of mobility PECS Cooling Vest PECS Cooling Vest Not as physiologically inefficient Not as physiologically inefficient Adds considerable weight Adds considerable weight

9 Objectives Validation testing for arms and legs Validation testing for arms and legs Mechanical Redesign Mechanical Redesign PCM Optimization PCM Optimization

10 Requirements Validation Testing: Validation Testing: Testing needs to be carried out in a scientific environment with the proper tools and equipment Testing needs to be carried out in a scientific environment with the proper tools and equipment Cycling Bike, Thermal Sensors, Heart Rate Monitor, Full Body Suit and/or Firefighter Suit, CoolPac Prototypes(2-4) Cycling Bike, Thermal Sensors, Heart Rate Monitor, Full Body Suit and/or Firefighter Suit, CoolPac Prototypes(2-4) Farmington Health Center laboratory and/or Gampel testing facility Farmington Health Center laboratory and/or Gampel testing facility

11 Requirements Provided constraints need to be met. Provided constraints need to be met. Work generated by test subject: Work generated by test subject: 300 Watts 300 Watts Test Cycle: Test Cycle: Measure initial vital signs and core body temperatures. Measure initial vital signs and core body temperatures. Donning of equipment Donning of equipment Repeating cycles of work and rest Repeating cycles of work and rest Make final measurements. Make final measurements. Age/Gender/Weight: Age/Gender/Weight: The age group should be focused in the range of years old as provided by the sponsor. The age group should be focused in the range of years old as provided by the sponsor.

12 Requirements Mechanical Re-Design : Mechanical Re-Design : Alteration to the prototype: Alteration to the prototype: Comfort/Durability Comfort/Durability PCM Alignment: Maximize Surface Area PCM Alignment: Maximize Surface Area Fastening: Easy to put on and take off Fastening: Easy to put on and take off

13 Requirements PCM Optimization : PCM Optimization : Research Alternative PCM for CoolPac Device: Research Alternative PCM for CoolPac Device: Attempt to meet sponsors PCM needs: Attempt to meet sponsors PCM needs: Latent Heat of Fusion: Wh/kg Latent Heat of Fusion: Wh/kg Melting Temerpatrue: 25-32°C Melting Temerpatrue: 25-32°C

14 Budget Price per Phase Change Material pad Price per Phase Change Material pad $3.75 each $3.75 each Need up to 50 pads (to test on arms & legs) Need up to 50 pads (to test on arms & legs) $3.75*50 = $ $3.75*50 = $ Sleeve materials Sleeve materials approx. $50 for cloth/sewing materials approx. $50 for cloth/sewing materials approx. $50 for fastening materials approx. $50 for fastening materials Total proposed budget: $300 Total proposed budget: $300

15 Project Flow Background research Consult Sponsor & Ask Questions Research PCM Test PCM Material Properties Select PCM

16 Validation Testing of current prototype Analyze Results Discuss design options (to make better) Design new prototype Results as expected? No Yes Discuss with Sponsor Finalize new design Create new prototype Presentation

17 Conclusion Project involves testing and design optimization Project involves testing and design optimization Great potential for financial success Great potential for financial success Low budget with respect to our goals Low budget with respect to our goals
