Electric Air Conditioner Instead Of The Program: Solar Energy Into Cool Air
Who does not want the hot summer air-conditioning in the office to enjoy the cool? Unfortunately, the traditional air cooler can not eliminate the annoying side effects?? Long-term consumption of large Energy , Energy efficiency is low, accelerating global warming. If people can successfully use sunlight to cool the family room or office that without a mistake?? Not consume large amounts of renewable energy is difficult, but also in the cooling process does not release too much carbon dioxide.

In fact, this revolutionary technology already exists, but is currently still in its infancy, and the high cost is amazing. Hamburg, Germany, a company called Thermodyna has proposed new solutions, hoping to create a demand-generated electricity, hot air and cold air of the home device, the power to replace the traditional high-energy air-conditioning system.
The core of the system is one named “Schukey” motor, able to convert sunlight into cold air. Refrigeration process, this motor only 5 cents a kilowatt, while comparison, the traditional air-conditioning costs per unit of electricity will need to 12-14 cents.
Thermodyna VolkerBergholter boss said: “The device is not using any Electronic Components, and virtually no component parts. “He described the device as” extremely simple. “It only needs two engines combine for the production of cold air Solar Energy Panels. Solar panels produce the steam is converted into mechanical energy boosters, mechanical cooling machine used to drive again. Absorption cooling machine room in the humid hot air, hot air into the compression and expansion had been cooled to 20 degrees Celsius, the room cooling.
Biggest advantage of this device is the most intense time in the sun, the people most in need of refrigeration, and solar energy more, the device easier to collect large amounts of energy to be used. Complementary relationship to better meet consumer needs. Thermodyna company plans to catch in 2010 to market the first batch of solar refrigerator.
High price high cost is a major problem
Over the years, researchers and Project R & D division has been working for the indoor use of solar thermal energy to cool the machine. But they did not with the traditional plug-in air-conditioned box to contend. Firth of German solar energy company called Solid Information consulting firms to assess each of the newly installed air-conditioning capacity of total output power up to 25 megawatts, which is only a small part of which belongs to Environmental protection Type of air conditioning. Solid company, a solar refrigeration technology experts OskarWolf said: “So far, the economic feasibility of this new technology is not high.” Regenerative cooling system needs 24-30 cents per kWh, which is both the traditional air-conditioning costs times.
Mainly due to the high cost of environmental green cooling system currently used in a very complex technology. The current approach is to mix water and coolant in place known as the “absorption cooling machine” in and use of solar heating. Case of thermal evaporation and condensation of coolant sprayed heat exchanger, the re-evaporation. Evaporation heat is used to extract moisture from the air, the air continues to flow after the heat exchanger to cool, and finally brought to the room cool.
Wolf said that the problem is that even such a small 15-kilowatt machine also requires a lot of power and up to 100 degrees Celsius temperature. In addition, to calibrate the solar energy and cooling systems are very difficult, “We spent a long time to master this technology.”
However, the clean-type green air conditioner market is quite enormous. According to the International Energy Agency (IEA) expects the impression that due to climate change, air-conditioning demand in Europe for 2020 will increase by 10%. Solar cooling device can meet those needs while avoiding the increase in carbon dioxide emissions, help reduce the negative impact on the climate. It also can reduce the peak power at noon, helping to ensure the stability of grid work.
Present, the German government on the purchase and installation of environmentally friendly air-conditioning provide health benefits. At the same time, the size of solar panels to collect more than 40 square meters of business, KfW will provide up to 30% of the investment sponsor.
New absorption refrigeration association?? “Absorption refrigeration” or “absorption refrigeration” is now the exclusive name of the new technology?? Hope that the German government can take further measures, such as providing dedicated adsorption refrigeration equipment subsidies. The EAW in eastern Germany solar panel manufacturers Sell Manager BerndHebenstreit said: “We are seeking talks with the national environmental sector opportunities.” In the context of the whole of Europe has also launched a similar campaign. Starting May 1 this year, implementation of the EU directive on renewable energy that the expectations on the promotion and dissemination of the technology, the Member States should adopt legislation to promote solar cooling and heating air conditioning use.
Major manufacturers involved in the largest revolutionary force
Government support for the technology will help to attract such as Vaillant and Viessmann heating technology company with such a large part of it. BDH Industry Association chief executive AndreasLücke, said: “If the government give full support, the company will more aggressively into solar energy research and development in refrigeration technology.” So far, the technology for low cost-effectiveness has not been enough attention. Instead, the industry is more focused on the development of other technologies, such as power reverse cycle air conditioning and heat pumps and so on.
These important large-scale manufacturers in the rapid innovation, the establishment of large factories and to carry out market Marketing Activities has extensive experience and sufficient capital, once these companies operate solar refrigerator for the greater interest, is bound to greatly promote the commercialization of the product. In addition, they do not need to develop their own refrigeration machines, only those committed to the technology developed in recent years, small innovative companies can be. In fact, as EAW, SKSonnenklima and Sortech this company have been or are preparing a small-scale production of solar refrigerator.
, For example, EAW company has produced a 15-200 kW absorption chiller. The Schüco solar energy technology company with the cooperation of the industry provides a good example. EAW production company refrigerator, and Schüco is responsible for the refrigerator combined with solar panels, then the combination of a good package system to the market.
EAW sales manager Hebenstreit said that at present, the market demand

Allied Electrical is the company manufactures and indirectly exports CP and CPM Coolant Pump, which are an immersion type Centrifugal Pumps. The primary objective of these pumps is dissipation of heat from the work piece and the cutting edges.
I want to buy a group absorption cooling, solar-powered cooling can 100 tons and I hope that your company provide me with a price offer with the specifications and diagrams of the group and the possibility of supply to Syria
Thank you very much
