- Does this control a real air conditioner?
- No. It is a virtual simulator for fun and lightweight temperature modeling in the browser.
- Where does the weather data come from?
- When you choose a city, the browser requests current weather from Open-Meteo. You can also use manual outside temperature and humidity.
- Is the cooling model physically accurate?
- No. The model is intentionally simple and transparent. It is meant to feel plausible, not to calculate real HVAC performance.
- Can I use this for heat safety decisions?
- No. Use official weather warnings, public health guidance, and emergency services for heat risk decisions.
- Can an online air conditioner cool my room without AC?
- No. It is only a browser toy and simulator. If your room is dangerously hot, use real cooling, shade, ventilation, hydration, and official local heat guidance.
- Why mention Europe heatwaves and homes without AC?
- Many European homes and rentals still do not have built-in air conditioning, so heatwave searches often include online AC jokes, portable AC comparisons, fans, and ways to cool a room without AC.
