Need for Electricity-Free Cooling System
Global temperatures are rising quickly, and heatwaves are becoming more frequent. Many regions face extreme heat but lack reliable electricity. This creates a strong need for alternative cooling solutions.
More than 700 million people still live without electricity. This increases the demand for low-cost and sustainable cooling systems. Important factors include:
- Rising global temperatures
- Limited power access in many regions
- Growing demand for affordable cooling
How the Electricity-Free Cooling System Works
The electricity-free cooling system is called Nescod. It stands for No Electricity and Sustainable Cooling on Demand. It uses ammonium nitrate mixed with water to create cooling.
This process is based on endothermic dissolution. When ammonium nitrate dissolves, it absorbs heat from the surroundings. This lowers the temperature effectively. Key features include:
- Uses ammonium nitrate and water
- No need for compressors or motors
- Based on natural heat absorption process
Cooling Performance and Efficiency
The electricity-free cooling system showed strong results during testing. It reduced temperature from 25°C to 3.6°C in just 20 minutes. This makes it highly effective for practical use.
Researchers found it more efficient than other salts like ammonium chloride. The system provides fast and reliable cooling. Key highlights include:
- Rapid temperature drop
- Higher efficiency than other salts
- Suitable for real-world use

Solar-Powered Regeneration Cycle
After cooling, the system can be reused without electricity. Solar energy is used to evaporate water from the solution. This allows the salt to crystallize again.
This process resets the system for another cooling cycle. It makes the technology sustainable and efficient. Key benefits include:
- Uses solar energy for regeneration
- Allows repeated use
- Reduces waste through water recovery
