This invention provides a primary uniform heater in the natural temperature preserving main body and it is conducted to a room needed to be heated, where the temperature can disperse openly; the temperature is transferred by the heat-conductive fluid by a main pump, or further by a shunt pump; that is, fresh air enters into the primary uniform air-heater through an open filtered inlet, and enter the primay uniform heater of the natural temperature preserving main body and then it is pumped throu...

A foundation construction, particularly useful for buildings and other supported structures in Arctic regions wherein a permafrost condition typically prevails, is provided by a construction pad having at least one or more perforated and ventilated conduits positioned within a cushion of air-permeable particulate material, said cushion containing the perforated conduit being substantially thermally isolated from the supported structure by means such as encapsulating with an insulating material. ...

A method and apparatus are provided for heating and cooling buildings, particularly chickenhouses, wherein low grade heat is obtained from below the frost line and, by heat exchange means, the low grade heat is used to heat or cool air which is then ducted into the building. This conditioned air circulates within the building and exits through horizontal vents extending substantially continuously around the periphery of the building near the floor thereof, which vents connect the inside of the b...

An air temperature control system which is highly energy efficient and virtually maintenance free. The system includes an intake conduit for receiving air at a non-selected temperature, an exit conduit for delivering the air at a controlled temperature to a preselected location, a heat exchanger located below the surface of the ground, and a heat sink preferably of limestone which surrounds the heat exchanger and which adjusts the temperature of the air flowing through the heat exchanger to a co...

Spectacles for reducing glare due to oncoming traffic while driving at night. The spectacles include a mask or filter that blocks light from entering the wearer's eyes when the source of light is on the opposing side of the highway. The mask may either be a part of the lenses of the spectacles or supported in front of the spectacle lenses by means of a "clip-on" device. If a perpendicular reference line is drawn on the lenses that passes through the optical center of the lens, the mask covers th...

A snow melting panel has a piping arrangement that includes straight pipe lines and U-shaped bend sections is provided. The panel can be sized such that the parallel length of the straight pipe lines is 300 to 5000 mm, and the perpendicular span of the straight pipe lines is 100 to 4000 mm. The piping arrangement may have a hot-dip galvanized layer or a highly corrosion resistant galvanized layer formed or provided only on the outer surface of the piping arrangement. For example, the gap between...

Trafficked surfaces built on foundations which remain substantially undisturbed during seasonal climatic cycles, particularly in permafrost and near permafrost regions where considerable disturbance of the ground beneath foundations is otherwise common. The foundations include combinations of insulation layers, heat sinks and/or thermal bleeds which dampen and prevent the cyclic climatic seasonal variations from affecting the earthen support under the foundations, in both cut and fill sections, ...

Wellbore heat loop systems, fillers for bores in the systems, and methods of the use of such systems; the systems in certain aspects having a heat loop wellbore in the earth having heat loop pipe extending down to one side of a bottom member and up therefrom on another side thereof, the bottom member in certain aspects having a body with first and second bores therethrough, the second bore sized and configured for securement thereat of an end of coil tubing; and, in certain aspects, filler mater...

A geothermal apparatus comprising a first pipe for receiving a heat exchange liquid therein and a second pipe for receiving the heat exchange liquid therein and having a web integrally connected to each of the first and second pipes, between such pipes for holding the second pipe at a predetermined distance from the first pipe. This pair of pipes, which are integrally connected, are installed in the ground in a hole or bore and then are connected to a heat exchanger having a fluid inlet connecte...

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 exce...
