Abstract:
A method for altering the temperature of a premises having a bed/foundation of stone/gravel material over a section of ground, a floor above the bed/foundation and a floor layer located between the bed/foundation and the floor, the method comprising the steps of:cooling a medium during the night in the summertime by heat exchange with cooler night air;circulating the cooled medium into a floor layer under a floor of a premises to cool the premises during the day; andestablishing a temperature difference between at least an upper portion of the floor layer and a ground under a bed/foundation located under the floor layer by carrying out said step of circulating the cooled medium in the floor layer in such a manner so as to cool the floor layer and the bed/foundation so that a lowest temperature of at least the upper portion of the floor layer substantially exceeds the temperature of the section of ground, the temperature difference preventing an undesired migration of moisture through the floor layer from the section of ground.
