Battery Powered Heating and Cooling Suit


Published on Jan 30, 2019

Abstract

The climatic conditions are changing with the era to era. In nowadays, climatic conditions are getting to be unusual to the people. Some of these conditions, when left unchecked, have provoked stunning passings. Because of this, people need to focus with respect to atmosphere conditions like, conveying an umbrella despite the fact that in summer season or spring season. While conveying these things, we may feel uncomfortable. To keep away from this issue, we are presenting Battery Powered warming and Cooling Suit. These suits can spare us from the dynamic Temperature related insults, for instance, warmth stroke, heat rash in summer season. Frostbite, hypothermia and others from the spring and stormy seasons. So these suits will keep the people more protected and agreeable in any season. This suit can naturally keep up the specific temperature inside the suit, in the event that it is exceptionally hot inside the suit, so as to lessen the temperature; it initiates the fan that is fitted to the suit. At the point when the temperature scopes to the predefined level, fan has consequently exchanged off.

For instance, if the temperature is too low inside the suite, it can switch on the radiator to expand the temperature inside the coat. At the point when the temperature scopes to the predefined level, the radiator must be exchanged off. In blustery season, downpour water is wiped out by the wiper which is organized to the suit.

Introduction:

Both very cold and very hot temperatures could be dangerous to health. Excessive exposure to heat is referred to as heat stress and excessive exposure to cold is referred to as cold stress. In a very hot environment, the most serious concern is heat stroke. At very cold temperatures, the most serious concern is the risk of hypothermia or dangerous overcooling of the body. The proposed system is a battery power heating and cooling jacket, in which the user can regulate the temperature of the jacket through his mobile. After initialization temperature sensor measures the wearable coat temperature according to person’s surroundings. The jacket to a mobile app via Wi-Fi. The mobile app will display the current body temperature and has tools to vary the temperature of the jacket according to user’s need. We can perform both heating and cooling operations as per the requirement. The jacket can work both in manual or automated mode. In automatic mode the jacket reads the temperature via temperature sensor, sends the data to the raspberry pi, the logical operation is performed by the raspberry, while signals out the peltier to either heat or cool.

Objective:

1. The usefulness and practicality of such a suit is the motivating factor of embarking on this project.

2. Ultimately, we set out to achieve a body suit that is easy to wear, comfortable, and provides simple and adequate controls that allow for any user to utilize it to their needs.

3. Its functionalities can be used to prevent the unfortunate condition that are caused by heat stroke, hypothermia, and other thermally induced maladies.

Existing System

Existing system is a heating/cooling jacket, in which the user can control the temperature through controls and thermo-electric devices that are embedded in the suit. The functionality of the suit is, once turned on, the device displays the temperature of the inside of the suit in an LCD displays. Initiating the hot or cold functions are as simple as pushing a button, and a rotary knob allows the user to control the internal temperature of the suit. The thermoelectric cooler is a solid state heat pump made of thermocouples of high-efficiency semiconductor material that creates a difference in temperature of its two sides when a voltage is applied and current runs through it. None of the current system contains IoT. Connectivity, Transfer of heat or cold is either through cooper tubes, through thermo conductive fluid. Existing system are all manual, either the jacket is controlled through knobs or on and off switch.

Proposed System:

The proposed system is a battery power heating and cooling jacket, in which the user can regulate the temperature of the jacket through his mobile. After initialization temperature sensor measures the wearable coat temperature according to person’s surroundings. The jacket to a mobile app via Wi-Fi. The mobile app will display the current body temperature and humidity, we can vary the temperature of the jacket according to user’s need.

RASPBERRY PI

Raspberry Pi is a series of credit card–sized single-board computers developed in the United Kingdom by the Raspberry Pi Foundation with the intent to promote the teaching of basic computer science in schools and developing countries. The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations.
All models feature a Broadcom system on a chip (SOC) which includes an ARM compatible CPU and an on chip graphics processing unit GPU (a VideoCore IV). CPU speed range from 700 MHz to 1.2 GHz for the Pi 3 and on board memory range from 256 MB to 1 GB RAMS.

CPU speed range from 700 MHz to 1.2 GHz for the Pi 3 and on board memory range from 256 MB to 1 GB RAMS. Secure Digital SD cards are used to store the operating system and program memory in either the SDHC or Micro SDHC sizes. Most boards have between one and four USB slots, HDMI and composite video output, and a 3.5 mm phono jack for audio. Lower level output is provided by a number of GPIO pins which support common protocols like I2C. Some models have an RJ45 Ethernet port and the Pi 3 has on board WiFi 802.11n and Bluetooth.

Peltier Plate

Thermoelectric cooling uses the Peltier effect to create a heat flux between the junctions of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). It can be used either for heating or for cooling, although in practice the main application is cooling. It can also be used as a temperature controller that either heats or cools. A Peltier cooler can also be used as a thermoelectric generator. When operated as a cooler, a voltage is applied across the device, and as a result, a difference in temperature will build up between the two sides. When operated as a generator, one side of the device is heated to a temperature greater than the other side, and as a result, a difference in voltage will build up between the two sides (the Seebeck effect). However, a well-designed Peltier cooler will be a mediocre thermoelectric generator and vice versa, due to different design and packaging requirements.
