Abstract
A method and device for altering the temperature of a premises, wherein a medium in the summertime is cooled by the cool night air and is brought into a floor layer directly under the premises for cooling the premises during the day. In order to minimize the risk of migration of moisture from the ground and upwards to the floor layer, the floor layer and an underlying foundation are cooled so that at least an upper portion of the floor layer reaches a minimum temperature which substantially exceeds the temperature of the ground under the foundation.
Claims25
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;
- and
- establishing 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.
A method for cooling a premises having a bed/foundation of stone/gravel material, a floor above the bed/foundation, a floor layer located between the bed/foundation and the floor and a conduit system located on top of the bed/foundation, 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;
- circulating the cooled medium through a conduit system on top of a bed/foundation located under the floor layer to cool the bed/foundation;
- and
- establishing a temperature difference between an upper portion of the floor layer and a ground under the bed/foundation during the step of circulating the cooled medium in the floor layer by cooling the floor layer and the bed/foundation so that the temperature of the upper portion of the floor layer exceeds the temperature of the ground below it sufficiently to minimize upward migration of moisture from the ground to the floor layer.
An apparatus for altering the temperature of a premises, comprising:
- a bed/foundation of stone/gravel material located above a section of ground;
- a floor of a premises to be cooled located above said bed/foundation;
- a floor layer located between said bed/foundation and said floor;
- a cooling device arranged to cool a medium by heat exchange with cooler night air during the night in the summertime for use in said floor layer for cooling said premises during the day and for cooling said bed/foundation such that said floor layer and said bed/foundation may be cooled to a minimum temperature which substantially exceeds the temperature of said section of ground so that an undesired upward migration of moisture from said section of ground through said floor layer is prevented.
An apparatus for cooling a premises, comprising:
- a bed/foundation of stone/gravel material;
- a floor of a premises to be cooled located above said bed/foundation;
- a floor layer formed on top of said bed/foundation and below said floor;
- a conduit system containing a medium located on top of said bed/foundation;
- and
- a cooling device arranged to cool said medium during the night in the summertime by heat exchange with cooler night air, said cooled medium being supplied to said floor layer for cooling said premises during the day and for cooling said bed/foundation, such that the temperature of an upper portion of the floor layer substantially exceeds the temperature of a ground below the bed/foundation to minimize upward migration of moisture from the ground to the floor layer.
