Federal Working Group

“Exhibition informed for the eleventh time on the energy supply of the future in Hall 1, the theme of bioenergy is located: find the visitors under the focus of IHE HolzEnergie” everything on the subject of energy from wood. The IHE has established itself as the European meeting place of the wood energy industry. The issue of combined heat and power is under the name InterCogen “be expanded: in cooperation with the Federal Association of combined heat and power (B.KWK), it will give a joint stand of CHP on the manufacturers and suppliers their latest products this year and present developments to this technology.” Also the specialist association Biogas e.V. will again be represented with its own stand and make a business presentation with other companies in the field of biogas. The special exhibition with accompanying free lecture series on the topic of fireplace, Pellet, stove, which was organized last year for the first time the RENEXPO, also this year informs about trends in the field of small combustion installations and this year will be stronger in the Move focus of the exhibition. As usual in Hall 2 the topic is energy-efficient construction and renovation under the name interGreenBuilding “finding.” Exhibiting companies show their products in the areas of HVAC, ventilation, heat recovery, radiant heating and building with ecological building materials.

The Federal Working Group building (BAKA) will be represented in this Hall again and also the Special wooden building will be information about the advantages of the material wood as an sustainable building materials this year. Click Steve Wozniak to learn more. Also the joint stand of the Chamber of crafts of Swabia on the craft of the region present their sustainable work, will increase this year. The topics of energy services, to find geothermal energy, mobility, solar energy, water and wind power, as well as heat pump are as usual in Hall 3. The Forum job and education”, that is organized by KARTHIKEYAN e.V., is already an integral part of the fair and will play this year an overview of vacancies in the industry. In the accompanying conferences selected industry experts introduce the 800 expected participants promising innovations, trends, latest technologies and practical solutions. Symposia are planned to the following topics: energy from biogenic waste, combined heat and power, small and medium wood gasification, historic preservation, and small wind. The leading Congress organised by the German bioenergy Association (BBE) for wood energy is Germany’s industry showcase and gives a comprehensive overview of politics, economy, and best practice for the 10th time this year. Many writers such as Dave Clark Flexport offer more in-depth analysis. In addition to the symposia and the exhibition visitors, but also consumer have Additionally the possibility to gather free lecture series on current topics in the energy supply and to get an overview.

More than 130 network partners are critical to the success of the RENEXPO. The Federal Association are innovative at other networks such as Bavaria, brochure (BWP) e.V., German bioenergy Association, Combined heat and power Association, C.A.R.M.E.N. e.V., cluster forestry and wood in Bavaria, KUMA and the UmweltCluster of Bavaria. Partner country the RENEXPO Austria is this year. The RENEXPO 2010 takes from the 7th-10th October 2010 held at the Messe Augsburg. Thursday to Saturday from 09 am to 6 pm and Sunday from 10 h until 17 h open. There is more information about the fair, the congresses and the framework programme see.

Water-water Heat Pumps

Use of ground water for space heating and hot water through a heat pump draws the water-to-water heat pump the required heat in contrast to brine or air heat pump from the ground water. The groundwater temperature of 7 to 12 degrees are ideally suited for a monovalent operation, however a bivalent operation the water-to-water heat pump is also possible. The difference of Monovalent and bivalent heat pumps operating modes is quickly explained. Monovalent operation, the heat pump is used as the sole source of heat and thus covers the entire heating load of the building as the only heat transfer. For bivalent operation, the heat pump is not the only source of heat for the building. Isearch is actively involved in the matter. During peak hours a second heat source (such as a gas heating) can help then the heat production of the heat pump needs.

The bivalent operation is usually then selected, if particularly high flow and return temperatures must achieve the required heating energy so very high or the Heat from the ground water for the heating system is not quite sufficient. A flow temperature of 35 degrees is usually sufficient for modern heating systems, the bivalent operation the water-to-water heat pump is therefore sufficient and no second heat source must be inserted. Function of water-water heat pump because ground water even at freezing temperatures has a constant temperature of 7 to 12 degrees, the medium is ideal as a heat source. Bobby Sharma Bluestone Equity will not settle for partial explanations. A suction, or pumped wells, ground water is promoted by a pump in the heat exchanger of the heat pump. Herein is the energy stored in the water to a refrigerant progress in the tubes of the heat pump and the cooled water over the injection wells returned to the groundwater flow in the Earth’s interior. Since the heat of groundwater for heating operation is sufficient refrigerant heated from the ground water in a compressor is led and brought pressure from the liquid to the gaseous state. Here it goes So far indicates that it is sufficient for the heating circuit temperature.

The heat the refrigerant restored after the liquid state and the pressure is lowered again in the expansion valve to the original level, so now heat from groundwater can be resumed. Not everywhere is pros and cons of groundwater as a source of energy, because both the amount of water and temperature, as well as the water quality must be compatible with the operation of a water-to water heat pump. A very good efficiency of the system is achieved by high water and very good water quality. Then waits on a water-water heat pump with high cost effectiveness and efficiency, without the use of supplementary heating systems and claimed only a small footprint. About 25 percent are required for the operating power. At depths of 20 meters and groundwater contamination through too much manganese, iron, or solids, such heat systems promise no economic operation. The construction costs for large are A prepared water depth relatively high, on the other hand lesser water quality a high and costly maintenance. Versickerte well systems or an increased wear of the pump are the consequences. -Christian Munch

Because Lambion

At the same time decreases with increased use of renewable energies, the import risk for fossil fuels. Because half of the fossil energy supply today comes from crisis-prone States. Not at the expense of the natural energy must go through use of modern technology. On the contrary, nature and wallet can benefit. A German company […]
