摘要:
The invention concerns a method and device for heating and cooling buildings. During heating for cooling, the air heated by geothermal heat energy and supplied from the subterranean layers is circulated at least in the air duct of a heat-insulating air-circulation system (11), which is preferably provided with an inner heat-insulating air gap, an air duct and an outer heat-insulating air gap and, from the room interior, covers the walls (8, 9), delimiting the outer environment and other unheated rooms, and ceiling parts (4) of the room to be heated or cooled. At the same time, the outer ambient temperature (tk) is continuously measured by a thermostat (48) mounted outside the building. When the condition t1 ≤ tk - 1 °C is satisfied, t1 being the temperature of the air circulating in the air duct, during heating, the air circulation is interrupted by means of the thermostat (48) and further heating of the interior (19) to a desired temperature, if necessary, is ensured by means of additional heaters which are preferably associated with the room. In contrast, when the room is cooled, the air, which is maintained at a given temperature by geothermal heat energy, is made to circulate when the temperature, which is continuously measured by means of a thermostat (47) disposed in the room, exceeds a given value. The air circulation is interrupted when the room temperature measured drops below a given value. The invention further concerns a heat-insulating wall covering which forms the heat-insulating air-circulation system according to the invention and comprises parquet-like plastics elements which can be joined to one another.

There is described a building structure defining at least one interior space and comprising at least one thermally massive structural element of a first material; a non-structural element of a second material, the non-structural element being located at a surface of said structural element to define a heat exchange air path therebetween; and means for selectively directing air along said path, the air, when so selected, being directed along said path either before or after passing into said interior space or before being discharged without entering said interior space. There is also described a method of controlling the temperature of an interior space defined by a building structure including at least one thermally massive structural element, the method comprising the steps of providing a non-structural element at a surface of said structural element so as to define a heat exchange air path therebetween and selectively directing air along said path either before or after passing the air into said interior space or before being discharged without entering said interior space.

Die Erfindung betrifft eine zweischalige Fassade für ein Gebäude mit einer Innen- und einer im wesentlichen transparenten Außenfassade (10, 12), zwischen der Innen- und der Außenfassade (10, 12) angeordneten Trennelementen (18, 46), die zwischen der Innen- und der Außenfassade (10, 12) abgeschlossene Gefache (24) bilden, und mit jeweils einer Einlaß- und einer Auslaßöffnung (26, 28) in der Außenfassade (10) für ein Gefach (24) zum Durchströmen von Luft. Erfindungsgemäß ist eine in Abhängigkeit von der Energieeinstrahlung auf die Fassade und/oder in Abhängigkeit von der Temperatur gesteuerte Lüftungseinrichtung (30) vorgesehen, die Luft in das Gefach (24) durch die Einlaßöffnungen (26) einsaugt und/oder aus dem Gefach (24) durch die Auslaßöffnung (26) ausbläst. Auf diese Weise wird eine einfache, bedarfsgerechte Be- und Entlüftung der Fassade gewährleistet.

PCT No. PCT/DK90/00227 Sec. 371 Date May 6, 1992 Sec. 102(e) Date May 6, 1992 PCT Filed Aug. 31, 1990 PCT Pub. No. WO91/03153 PCT Pub. Date Mar. 21, 1991.The invention relates to an apparatus for venting a building such as a greenhouse, by means of a sheet member which can be mounted in one or several openings of the building. The sheet member comprises a frame with four sides wherein are provided on at least two horizontal controls, which are formed as first rack bars. The frame has a horizontal edging and several parallel slats provided on at least one side hereof with a layer made of windproof and elastic material. A pinion is mounted in rotatable position opposite each guide on the edging, said pinion comprising a first and a second gear, the first gear being in mesh with the mentioned first rack bars, and the second being in mesh with teeth on the second rack mounted in movable position on the edging. A movement by the second rack bar in longitudinal direction will cause the second gear and consequently the first gear as well to rotate, whereby the edging is caused to move upwards or downwards via the first rack bars depending upon the direction of movement of the second rack bar. Consequently, the layer will either close off or clear an opening to the effect that air may vent the interior of the building.
摘要:
A building (10) of generally spherical configuration has a lower portion and an upper portion and includes an outer skin (13) of first triangular panels and an inner skin (12) of second triangular panels. Substantially all of the panels are light-transmitting, and may be made of glass. Partitions extend from the lower to the upper portion of the building between the two skins and divide the inter-skin region into a plurality of sectors running from the lower to the upper portion of the building. Particulate insulative material (9) is provided, along with apparatus for selectively filling the sectors with insulative material by delivering insulative material to the upper ends thereof, and to selectively empty the sectors of insulative material by withdrawing insulative material from the bottom ends thereof. The building can be controlled in such a way as to allow open or empty sectors to track the sun in the winter, thus maximizing solar heating, and to face away from the sun in hot weather, thus minimizing overheating while allowing light entry.
摘要:
A heat pump using zeolite as an adsorbent (Fig. 3) wherein thermal energy from adsorbent zeolite in a one hermetically sealed space (121) is used to heat desorbing zeolite located in another hermetically sealed space (120), such heat being conveyed by heat exchanger conduits containing a fluid which, before heating the desorbing zeolite, has its temperature increased to about 400 F (205 C) by a gas flame (at 151), the adsorption and desorption phases being changed between the zeolites in each cycle by reversing the fluid flow in the conduits. Cooling and heating for a building or other purposes are provided through the condenser (122) and evaporator (124) respectively for the working gas (water) which is desorbed and adsorbed into the zeolites. A propagating temperature front is established through the fluid - to-zeolite heat exchanger conduits to provide utilization of as much as ninety percent of thermal energy available during the desorption/adsorption phases.
