Cooling 1: Pads with a passageway

摘要

Pad cooling is called a simple yet effective way of reducing the inside temperature of a pig-house, even in places where the outdoor climate is humid as well as hot. The principle behind the method is the known one of using warmth to evaporate droplets of water. In this case the evaporation removes heat from the air passing through the honeycomb surfaces of a wet-cell pad.
