released from electronic devices like ac

Problem or Opportunity

   a major amount of heat is released from ac into the environment due to this nowadays we face many environmental problems like climate change. To resolve that problem is our main moto

Waste heat-

    Waste heat is heat that is produced by a machine, or another process that uses energy, as a byproduct of doing work. All such processes give off some waste heat as a fundamental result of the laws of thermodynamics. Waste heat has lower utility (or in the thermodynamics lexicon lower exergy or higher entropy) than the original energy source. Sources of waste heat include all manner of human activities, natural systems, and all organisms, for example, incandescent light bulbs get hot, a refrigerator warms the room air, a building gets hot during peak hours, an internal combustion engine generates high-temperature exhaust gases, and electronic components get warm when in operation.

air conditioner-

Air conditioning, often abbreviated as A/C or AC, is the process of removing heat and controlling the humidity of air in an enclosed space to achieve a more comfortable interior environment by the use of powered air conditioners or a variety of other methods, including passive cooling and ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). 

Willis Haviland Carrier was an American engineer who invented modern air conditioning. Carrier invented the first electrical air conditioning unit in 1902.

Problem-

According to the International Energy Agency (IEA), as of 2018, 1.6 billion air conditioning units were installed, which accounted for an estimated 20% of electricity usage in buildings globally. The number is expected to grow to 5.6 billion by 2050. The United Nations called for the technology to be made more sustainable to mitigate climate change using techniques including passive cooling, evaporative cooling, selective shading, windcatchers, and better thermal insulation. CFC and HCFC refrigerants such as R-12 and R-22, respectively, used within air conditioners have caused damage to the ozone layer. climate change and global warming Both issues happen due to the venting of refrigerant and the venting of heat from ac to the atmosphere.

solution-

The thermoelectric effect directly converts temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, heat is transferred from one side to the other when a voltage is applied to it, creating a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side.

DISPOSAL-

The disposal procedures for air conditioners are mostly the same, be it a window air conditioner disposal, or a minisplit. They are also dependent on your location. But wherever you choose to dispose of your air conditioner, it will be done by qualified professionals. Do not attempt to perform the same job at home, as that could lead to serious injury and environmental damage. Let’s have a look at some of how you can dispose of your air conditioner.

• Send It off to a Scrap Yard.
• Search for a Rebate Program.
• Consult Your Local Disposal Agency
• Consult Your Local Disposal Agency
• Go Environmentally Friendly & Recycle
• Refurbish Your Old Air Conditioner
• Be a Responsible Citizen!

Peltier effect as a solution -

We use the Peltier effect according to the objectives of our project Using a peltier module the size of a condenser or adding several smaller peltier modules, we will create a device that will convert the heat emitted from the condenser into electricity, which can then be used in a variety of ways.
