| 20100083952 | Adaptive self pumping solar hot water heating system with overheat protection - Solar collectors heat and self pump heat transfer fluid at reduced system pressure without mechanical intervention for heat exchange with hot water in a storage tank. Slugs of hot fluid are pumped by steam bubbles formed in solar collector tubes through an upper manifold and an exit-tube into an upper hot fluid reservoir. Hot fluid flows downward through a heat exchanger at the tank. Cold fluid returns to a lower reservoir. Vapor flows from the upper reservoir and is condensed by cooler water and walls of the lower reservoir. The cool fluid returns from the lower reservoir to a lower manifold supplying the collector tubes. Below ambient pressure is automatically established in the system. When heat build-up increases pressure in the system, fluid flows to a third closed variable volume reservoir. A float valve in the bottom of the third reservoir allows liquid to return to the system when it cools. | 04-08-2010 |

| 20110005514 | SOLAR THERMAL HEATING UTILIZING DYNAMIC PARTICLE FLOW BALANCING - A solar heating apparatus, which includes a panel having one or more layers or a group of such layers, wherein one or more layers among such a group of layers constitutes a transparent medium. The panel includes at least two other layers among the group of layers, which constitute a reflective medium. The panel additionally includes one or more spaces formed between the layers and at least one other space formed between the other layers. A heat transfer fluid can be located within the space between the layers. The heat transfer fluid contains heat-absorbing particles, which are suspended in the heat transfer fluid and subject to a flow-force through the panel in a direction against a force of gravity. The heat-absorbing particles are held in light in the panel via a balance of a flow-force and the force of gravity. The heat-absorbing particles drift to the bottom of the panel when the flow-force stops. | 01-13-2011 |
| 20110114084 | HEAT RECOVERY INSTALLATION USING SOLAR ENERGY - A heat recovery installation using solar energy includes a three-channel plate, in which the first channel layer, viewed from the outside, alternately discharges used air and supplies fresh air. The third channel layer, viewed from the outside, ensures the supply of used air and the discharge of fresh air, while in the second channel layer, viewed from the outside, the heat exchange between the used and fresh air takes place according to the counterflow principle. In order to produce this flow, small apertures are provided in the second and third plates, viewed from the outside, of the three-channel plate, as a result of which the flow in the channel layer, viewed from the outside, is at right angles to the channel plate. By making the airflow quicker than the heat flow (Pe>>1), no heat can flow from the inside to the outside, except for a small loss flow through the partitions and through radiation and, conversely, mainly heat exchange of the used to fresh air according to the counterflow principle takes place with heat recovery. If the channel plate is made of transparent material and the inner plate is provided with a (sun)light absorber, then (sun)light which shines on the three-channel plate is also converted into heat and given off directly and indirectly to the fresh air. | 05-19-2011 |
| 20110297144 | TEXTILE BASED AIR HEATER SOLAR COLLECTOR - In the active type textile based air heater solar collector, as solar energy absorber plate a black single layered homogenous non woven textile surface (fabric) has been used instead of black metallic, ceramic, plastic or composite plates, nets, mats, woven or knitted fabrics and passing of the air to be heated through this textile surface has been achieved. The movement of the air in the collector and the transportation to the space to be heated or drying medium is provided by a fan which is connected to output or input side of the collector. It is also possible to connect two fans both input and output sides of the collector. | 12-08-2011 |
| 20120017888 | Solar Energy Device - The present invention is a solar energy device that uses an improved light collector to collect sunlight. The improved light collector is a translucent, and preferably transparent, solid sphere. The light collector transmits sunlight that is incident thereon and emits the light to a focal point on the other side of the sphere. An energy-receiving medium is located at or near the focal point of the emitted light and absorbs energy from the emitted light. The energy-receiving medium uses the energy from the emitted light in accordance with the desired function of the present invention. | 01-26-2012 |
