If that heat is released in a 500 litter water tank: Typical air conditioners can produce about 2 kW of heat. I've never seen a water tank used as a heat sink for an air conditioner, but they were used for stationary engines some time ago. If the air is hot and humid, the fan will actually make you feel hotter. If the air is colder than 36☌ or below 100% humidity, it will carry heat away. It gives you a cold sensation is because it promotes air circulation, which improves heat/water exchange with your skin. The ceiling fan doesn't cool down anything, it only produces additional heat (though not much). This (heat transfer from a colder body to a hotter one) is exactly what an air conditioner does.ĭumping heat into an electrical outlet while cooling your house is what a perpetual motion machine of the second kind would do. In the second object than eliminated from the first. Essentially, you cannot simultaneously lower the entropy in a closed system (e.g your house) by transforming heat into a different form of energy, and transferring heat from a colder object to a hotter one requires work, so that more heat is produced The possibilities of transforming heat into any other form of energy are limited by the second law of thermodynamics.
