1. A temperature regulator comprising:

  • a container having an inner chamber and an upper wall adapted to be in thermal contact with the underside of the roof of a structure;

    a supply of water filling said chamber, said water being in contact with essentially the entire effective heat transfer area of said upper wall; and

    insulation disposed in said chamber and located adjacent to said upper wall, said insulation defining passages that allow the water to flow vertically through the insulation,whereby the radiation of heat from the roof into the night sky cools the water above the insulation and the remainder of the water is cooled by convection as relatively warmer water below the insulation circulates upwardly through the insulation and cooler water above the insulation circulates downwardly, and heat transfer to the interior of the structure is minimized during the day by the insulation and the thermal mass of the water.
