Problem to Solve:
The continuous operation of water motors in Personal Air Cooler for room , leads to unnecessary electricity consumption and water wastage. Additionally, the absence of intelligent temperature control in traditional cooling systems results in inefficient energy usage and reduced user comfort.
Solution:
We will convert a Personal Air Cooler into a Smart Energy saving Personal Air Cooler. Automation System that intelligently controls the water motor operation based on predefined intervals and temperature conditions. This system will reduce energy consumption, reduce water usages and enhance user comfort in residential cooling applications.
Functionality and Features: Interval-based Water Motor Control: The system will automatically turn on the water motor for one minute and then turn it off for the subsequent three minutes in a repeating cycle. This intermittent operation ensures efficient cooling while minimizing water usage.
Intelligent Fan Control: Using the Temperature & Humidity Sensor V2.0 (DHT20), the system will monitor room temperature conditions. When the temperature falls below 18 degrees Celsius, the motor will be turned off to conserve electricity. Conversely, when the temperature exceeds 27 degrees Celsius, the system will turn on the motor for cooling .
Seeeduino XIAO Integration: The Seeeduino XIAO will serve as the brain of the system, coordinating the operation of the water motor, fan, and temperature sensor. It will facilitate the timing and control logic to achieve the desired intervals and temperature-based actions.
Expected Benefits:
Energy Conservation: let's calculate the potential energy savings and carbon emission reduction achieved by implementing the Smart Evaporative Cooler Automation System for 10 lakh (1 million) users.
Assumptions: Water motor power consumption: 40 watts
Daily operation duration: 12 hours
Months of usage per year: 4
Energy Savings per User:
Total power consumption per day without automation = 40 watts * 12 hours = 480 watt-hours (or 0.48 kWh)
Total power consumption per year without automation = 0.48 kWh * 30 days/month * 4 months = 57.6 kWh
With the automation system, the water motor will operate for 1 minute and then remain off for the subsequent 3 minutes in a repeating cycle. This results in a 25% reduction in water motor operation time.
Total power consumption per year with automation = 57.6 kWh * (1 - 0.25) = 43.2 kWh
Energy Savings per User = 57.6 kWh - 43.2 kWh = 14.4 kWh per year
Energy Savings for 10 Lakh Users:
Total energy savings for 10 lakh users = 14.4 kWh/user * 10,00,000 users = 144,00,000 kWh (or 144,000 MWh)
Carbon Emission Reduction: Assuming an average carbon emission factor of 0.5 kg CO2 per kWh of electricity generated (which may vary by region and energy source), we can estimate the carbon emission reduction.
Carbon Emission Reduction for 10 Lakh Users = 144,00,000 kWh * 0.5 kg CO2/kWh = 72,00,000 kg CO2 (or 720,000 metric tons of CO2)
By implementing the Smart Evaporative Cooler Automation System for 10 lakh users, we can save 144,00,000 kWh of electricity annually and reduce carbon emissions by approximately 720,000 metric tons. These significant energy and environmental savings contribute to a greener and more sustainable future.
Water Conservation: The intermittent water motor operation will minimize water usage while maintaining optimal cooling efficiency.
Enhanced User Comfort: The intelligent fan control based on temperature conditions will ensure comfortable room temperatures while conserving energy.
In conclusion, the "Upgrade Old Air Coolers to Smart Coolers to save Electricity and water to save environment" will provide an intelligent and efficient solution to conserve energy and water in residential cooling applications. By leveraging the capabilities of the Arduino microcontroller and the Temperature & Humidity Sensor, the system will optimize the operation of the evaporative cooler, enhance user comfort, and promote sustainable cooling practices.
