The first refrigerators, in like manner say, were built as ice houses. These buildings was comprised of man-made underground chambers, that had been built close to natural sources of winter ice for example freshwater lakes. During winter, this ice and snow would be packed in the ice house in addition to straw or sawdust which was useful for insulation. The ice house kept the ice intact for several months at a stretch, even through summer.
