Key Takeaways 🧊

  • Using copper tubing and other components, it is possible to create a DIY air conditioner that can reach freezing temperatures.
  • This homemade air conditioner involves the use of an evaporator and condenser to cool the air in a room.
  • The process involves the circulation of gas and heat through the copper tubes to achieve the desired cooling effect.

Crafting an Icy Air Conditioner: A Detailed Overview ❄️

Creating the Evaporator 🪴

When crafting a DIY air conditioner, it starts with the creation of the evaporator. This component is essential for cooling the air within a room. The evaporator is formed from a 4.7mm copper tube, which is straightened and bent to the desired shape using a tube bender. Once completed, this evaporator is used to facilitate the cooling process by evaporating the liquid refrigerant and absorbing heat from the surrounding air.

Developing the Condenser 🌀

The condenser is another vital component in the construction of a homemade air conditioner. It is responsible for transforming the hot, gaseous refrigerant, after passing through the evaporator, back into a liquid form. The heat absorbed from the air in the evaporator is released during this process, and the condenser usually features a fan for additional cooling. As part of this DIY project, a 12-volt computer fan and a sealed 6-volt water pump are utilized to facilitate proper functioning.

Assembling and Filling the Air Conditioner 🛠️

Once the evaporator and condenser are constructed, it is necessary to connect these elements to a suitable platform using a two-component adhesive. Additionally, a thin 3mm copper tube, as a capillary tube, is included to regulate refrigerant flow. This capillary creates the necessary pressure for the conversion of the refrigerant from liquid to gas form, contributing to the cooling of the air. The junctions are then secured and sealed using appropriately sized silicone connection tubes, and the system is filled. Instead of using traditional freon, a gas refill for lighters is used, applying pressure to create the cooling effect in the air conditioning system.

Working of the Air Conditioner ❗️

The process starts with the introduction of gas to fill the homemade air conditioner and is facilitated by a pump to circulate the gas throughout the system. As the gas circulates through the copper tubes, compression and expansion occur, leading to a change in temperature. The expansion of the gas within the copper tubes results in a decrease in temperature, causing the absorption of heat from the surrounding environment. This can lead to condensation and even the formation of ice if the humidity levels in the air are sufficiently high.

Conclusion 🌬️

In conclusion, creating a DIY air conditioner with the ability to reach temperatures as low as -32°C is an achievable project through the effective use of copper tubing and other essential components. By understanding and following the processes for crafting the evaporator, condenser, and the required operation of the system, it is possible to create a functional, homemade air cooling solution.
