Question

how does a whole house fan apply to the law of thermodynamics?

Answer 1

Thermodynamics concerns the flow of heat in differing temperatures with other elements remaining steady. The whole house fan disrupts this by constantly moving air, which may be of a lower or higher temperature through the space. Depending on use, the fan may produce more comfort because the air is moving or may increase the rate of heat loss inside the house by constantly supplying a lower temperature mass of air to absorb heat.
