Project Summary

We are desiging a jacket which will provide cooling effect to the bike riders during the hot summer days  This wearable jacket works according to the atmospheric conditions. If the atmosphere is hot than the required condition, then it gives the amount of coolness to the human body, without causing any side effects. In this jacket. We are using Peltier module, Thermoelectric cooler (TEC) which can transfer heat from one side of the device to the other side with consumption of electrical energy. A Peltier module works opposite to thermocouple. In Peltier Cooler, peltier effect is used, whereas, in thermocouple, a temperature difference produces electric power. The operation of both depends upon thermoelectric effect. This effect can be used to generate electricity, measure temperature, to cool objects, or to heat them. In this jacket we will make sure to use solar films for generating power. A Peltier module works on the principle of ‘Peltier Effect’ that is when DC current flows, heat transfers from hot side to cold side, so that one side gets cool while the other gets hot. The hot side is attached to a heat sink so that it remains at a regulated temperature and it drives the heat away from the hot side into the atmosphere.

We are going to use tubes which will be wound around the jacket; which will be filled with water or any other eco-friendly fluid. A water pump is used if tubes are filled with water(sucks water/ air from outside atmosphere and circulates water/air over the Peltier cooler.

We are going to connect temperature sensors mainly LM35 (low cost digital temperature) with microcontroller in order to know the temperature. We will be using Arduino lilypad here; it is designed for e-textiles and wearables projects. It can be sewn to fabric and similarly mounted power supplies, sensors and actuators with conductive thread.

Project Objectives

Primarily, there were alot of objectives when we opted for this project but the most important are mentioned below

1) To develop a jacket which will acts as a coolant for motorcyclist especially. 

2) To ensure temperature throughout the jacket remains same.

3) To ensure temperature doesn’t get below too much (not below from 30 deg celsius), otherwise it will affect our body tissues and enzymes

Project Implementation Method

The proposed model is a jacket which consist of Peltier sensor heat sink, water pump, Arduino microcontroller, current controlling circuit, solar films, temperature sensor  and 12V battery.

The colder side of the Peltier module(12706) is attached with the water block through thermal solution whereas the hotter side is attached with the heat sink. The heat sink is finally attached with 12V fan. The water is sucked by pump and supplied to one end of the water block .The other end of the water block is connected to the water tanks through the pipe and form a close loop and in this way the process continues. The temperature sensor LM35 is used to measure the internal temperature of the body. and provides  electrical output relative to the temperature measured in Celsius. Temperature is controlled by current controlling circuit according to the environment. The Output of the temperature is displayed on the LCD. The current controlling circuit is used to regulate the current corresponding to temperature. When excessive cooling is required, the circuit will draw 6 amperes of current and when the required temperature is reached, it will draw current corresponding to the temperature which is done with the help of Arduino. 12V battery is used for supplying power to fan , Peltier, sucking pump which are connected in parallel. To use the battery for the sufficient time, flexible solar films are introduced to produce electricity by which battery life will be increased as it recharge again and jacket can be used for long time duration. The battery, water tank along with heat sink is placed in a separate bag where as the pipe and sensors are  assembled at the inner back side of the jacket. The solar films are attached at the outer the jacket so it is directly comes in contact with the sun.

Benefits of the Project

• Due to global warming, the climate of the world is changing which ultimately causing melting of glaciers and increasing of temperature and due to this summer season is getting much hotter in the world especially in Pakistan. This rising temperature causing heat stroke ultimately increasing the casualties of human being. This cooling jacket will act as coolant for the people especially for the bike riders.
• There are certain types of job where people are bound to work at high temperature places where they are more exposed to high temperatures like blast furnace job and extraction of metals from their ores etc.On slight modification, this cooling jacket will help them to perform their tasks easily without harming them with slight modification.
• In this project, we are using solar films which will charge the batteries automatically in the daytime and will reduce the cost of external battery. 

Technical Details of Final Deliverable

1) ensuring that the temperature throughout the jacket remains same.

2) designing of solar films on the basis of rated voltage of peltier module, fan, water pump.

3) Ensuing that the jacket don't get too much bulky by connecting the peripheral equipments 

4) Battery to selected which has good ampere hour rating.
