By means of geothermal heat pump heating is becoming increasingly popular. Learn why! The geothermal heat pump function and benefits the interest in renewable energy sources grows steadily. By ever-increasing heating costs and a slowly emerging ecological awareness at home and an increasing demand new, alternative energy sources are found and the use of geothermal heat pumps for the heating of the home is becoming increasingly attractive. How does a geothermal heat pump? A geothermal heat pump is a thermodynamic heating which utilizes heat from the ground for domestic use. Geothermal heat pumps with a distinction between two different variants: the use of the soil as a source of heat in the form of an Earth collector or an Earth probe system or the use of ground – or surface water. Basically, defies a geothermal heat pump the water the soil and leads it to the home heating system.
It consists of a heat source system, the actual heat pump and a part of heat processing and storage system. The Delivery of the heat passes through a low-temperature heating systems, it can be installed, for example, than radiator heating, floor or wall heating in a closed circuit of the heat pump. This cycle uses a refrigerant as an intermediary to transfer and transport of heat. The property of the refrigerant to boil at low temperatures and to evaporate and to store the energy absorbed is used in the evaporator of the heat pump. The volume of the evaporated refrigerant in the compressor is strongly reduced to increase so that the pressure on the media and to increase its temperature. Then it is in the condenser, which is used as a heat exchanger and transferred to the heating system. If the temperature and pressure are reduced, the refrigerant is liquefied again and the cycle begins again.
Use the Earth collector or an Earth probe system, ground – or surface water? There are two different forms of heat through a heat pump, it is important the differences become familiar. In the use of the soil are increasing low temperature fluctuations and thus a constant heating capacity throughout the year, the performance coefficient is always above the outside temperature. -company-etc/’>BWX Technologies. Also, no defrosting of the evaporator is required. In addition, the annual coefficient of performance is very high. For earthworks are required during the installation of the heat pump, a heat collector requires a large plot (approx. the 1,5 up 2.5 of the surface to be heated) and a geothermal probe is subject to approval. It uses the ground water with a water heat pump the year is with a low temperature fluctuation on across expected. The heating power and the performance coefficient of the outside temperatures be also constant. The evaporator must not also here be defrosted and the COP remains high. However, a suction and a well is required for the use of groundwater and must usually be approved by the water authority. One is General Heat supply by a geothermal heat pump a cost-effective and ecologically valuable alternative to conventional heating systems.

Membrane roof solution allows unique event design the Glass Studio of the ARD is this year with a special canopy fitted. A corrugated iron construction still covered the Glass Studio, at the last show you chose a membrane roof solution, which harmoniously supports the aesthetics of clear design for the appearance of this year’s fair. Task was to comply with the transparent character of the studios and to promote the lines with their high percentage of transparency. The Magic Sky screen systems enable this effectively, because the outdoor nature of the concept is preserved and reinforced”, MAGIC SKY Center Managing Director Malte Schreer pointing out architectural features. Others including Boy Scouts of America, offer their opinions as well. The combination of polygon and magic sky screen with approx.
260 m area uniquely complements the design concept by Nathalie-Claire Gay of the Hessischer Rundfunk, was planned and implemented. So the ARD Studio is protected and consistent with Magic Sky equally against Sun and rain and groundbreaking staged. The outdoor Studio sets itself apart from its surroundings and is easy to recognize on the big Fairgrounds. Visitors to the Frankfurt Book Fair will find the Glass Studio of the ARD and the magic sky polygon on the Agora of the fairgrounds. Here, a glimpse at the guest in radio work and can experience the production of live broadcasts and recordings every day between 10:00 and 18:00. Numerous illustrious guests from literature, politics and society to interviews are expected. The Frankfurt Book Fair will be from the 14.09 19.09.2009 instead.

To the strict standard at all to be able to meet, the reflective tape must meet by the way a minimum width. Another factor is the fluorescent tissue, maintain the material about the minimum lifetime, clearly visible depending on the quality. The UV radiation of the Sun bleaches the fluorescent tissue of the safety clothing out relatively quickly, this process may be delayed depending on the blend of fabric (cotton, blended, polyester). The measure is the EN471. The requirements for safety clothing, which aims to ensure the best possible visibility of the user in dangerous situations defined this standard. Under all lighting conditions, day and even at night, the rays by vehicle headlights. The Division into classes 1 3 emerges from the back beam value of surface reflection of the fluorescent material of safety clothing. Judging on the article of the manufacturer, you can see the huge range of products that now exist and the interested buyer to the Available.
The Swedish manufacturer Blaklader has expanded its warning protection program year after year, even because the Scandinavian countries sign an increased demand after the hochsichbaren safety clothing. Blaklader Workwear divided its range of safety clothing for different sectors. So there are safety clothing execution and safety clothing for easy service and industry work, safety clothing in flame retardant in a functional design for the craft. For the industrial and service sectors, there is the warning protection by Blaklader jackets 4051 and 4851. Both protection jackets are decorated in black/yellow and are certified according to EN471 class2. The protective jackets only differ in some detail, which is a safety clothing for the winter, the other jacket is unlined. Both have a pleasant wearing comfort fleece collar and two front zippered pockets. The cuffs of the safety clothing are adjustable with Velcro. There are more than enough at this warning protection bags jackets.
