Ce qu'il fait

Our evaporative air cooler efficiently cools and dehumidifies air, eliminates bacteria and viruses with UV light and filters, and diffuses pleasant scents. Consuming only 150 watts, it’s a health-conscious, eco-friendly, and cost-effective cooling solution.

Votre source d'inspiration

Our inspiration comes from rising global temperatures due to climate change. Traditional AC units consume excessive power, are costly, and often require prohibited external units. Standard ventilation systems fail to cool homes adequately, and AC units lack portability. These challenges led us to create a portable, energy-efficient cooling solution that promotes healthier indoor air quality. Our advanced technology cools, dehumidifies, and purifies the air, providing a comprehensive and eco-friendly alternative to conventional air conditioning systems.

Comment ça marche

Our evaporative air cooler works by utilizing a closed cylinder with water and advanced mist makers to increase the contact area between water and air, maximizing evaporation efficiency. Air enters through an inlet fan, where the heat pump's hot junction heats the incoming air, increasing its capacity to hold moisture. This process enhances the system's effectiveness by allowing more evaporation, thereby burying more heat in the water's phase change. Inside, UV light and filters eliminate bacteria and viruses for cleaner air. The cooled air passes over the cold junction of the heat pump at the outlet, where excess moisture condenses. Additionally, the system features an odor diffusion function to add pleasant scents to the cooled air. Consuming only 150 watts, this innovative device offers a portable, eco-friendly, and cost-effective solution for superior indoor air cooling and purification.

Processus de conception

Our design process involved multiple iterations to optimize our device's cooling efficiency and functionality. Initially, we used a submersible pump system, commonly found in aquariums, to circulate water. However, we discovered mist makers, which create a fine mist of water particles. These mist makers not only provided better water distribution but also cooled the air through the sudden expansion of water, enhancing the cooling effect. This led us to adopt mist makers for our design. We began with an edgy cuboid shape but transitioned to a cylindrical form. This allowed us to place the air inlet off-center, creating a whirl effect inside the cylinder. This increased the contact area and interaction time between air and water, significantly boosting cooling efficiency. Our initial design featured a higher top cap, which we later modified to a shorter version. This change reduced the water-air contact volume but increased the top cap's rigidity, resulting in a more robust and durable design. Lastly, we integrated a twin heat pump system to enhance performance. This system heats the inlet air after dehumidifying some of its moisture. By doing so, it enhances the air's capacity to hold moisture, increasing the cooling process's effectiveness.

En quoi est-il différent ?

Our evaporative air cooler revolutionizes cooling with several unique features. It consumes only 150 watts of power, significantly less than the typical 3,000 watts per hour used by standard AC units, making it an incredibly energy-efficient and cost-effective solution. Additionally, the integrated heat pump increases the air's moisture-carrying capacity by heating it at the inlet, enhancing the cooling effect through more efficient evaporation. The device also condenses moisture at both the inlet and outlet, boosting efficiency and effectiveness, and allowing it to function even in 100% relative humidity. Unlike desiccant dehumidifiers, our cooler operates simply by adding water, eliminating the need for additional desiccant materials. These innovations position our cooler as a superior alternative, offering enhanced performance, energy savings, and versatility in various environmental conditions.

Plans pour l'avenir

Our future plans include integrating a Joule-Thomson principle-based structure to pump heat, reducing part quantity and complexity. We aim to develop smaller, portable cooling machines for personal use, making them easy to carry and use anywhere. Additionally, we plan to create industrial mega machines designed to efficiently cool large factory spaces. For home use, we envision producing hangable variants to replace traditional AC units, offering a more efficient and compact solution for residential cooling. These innovations will enhance our commitment to providing versatile, energy-efficient, and eco-friendly cooling solutions.
