Wagih’s Hybrid SystemCooling PowerLimited by humidity levels.High, but energy-intensive.Maximum performance in all climates.Power ConsumptionVery Low (Pump + Fan).High (Compressor load).Optimized (Lower compressor strain).Environmental ImpactLow.High (Heat rejection).Eco-friendly (Water-cooled condenser).Control SystemManual / Basic.Basic Thermostat.Smart (AI / ESP32 Sensors Integration).2. The Innovation (Why it's unique?)

The core innovation lies in the Synergistic Cooling Effect. Unlike standard units, this design uses the water-cooling stage to pre-cool the refrigerant condenser. This reduces the thermal load on the compressor, allowing it to reach the set temperature faster and with significantly less electrical amperage (approx. 30% energy saving compared to standard portable units).

3. Operational Intelligence

Using the ESP32 microcontroller, the system monitors ambient humidity and temperature to select the most efficient mode:

Dry Mode: Prioritizes evaporative cooling to save energy.

Humid Mode: Activates the Freon cycle for dehumidification and cooling.

Turbo Hybrid: Both systems work simultaneously for rapid cooling and maximum performance.

4. Technical Specifications

Compressor Power: 1.25 HP.

Current Draw: 5.5 Amperes (Stabilized).

Connectivity: Wi-Fi / IoT enabled via ESP32.

Cooling Media: Dual-stage (Refrigerant Coil + High-Efficiency Cooling Pad).Technical Report: Hybrid Cooling Innovation
