Environmentally friendly, almost electricity-free solar cooling also serves as a heat pump

[font size=4]Demand and the need for cooling are growing as the effects of climate change intensify. VTT Technical Research Centre of Finland and German company ZAE Bayern have built an emission-free, solar-powered chiller; a pilot system has been tested in Finland and Germany. The potential market is world-wide, particularly in warm countries.[/font]
[font size=3]The production and consumption of solar cooling are simultaneous. A property's cooling needs are highest when the sun is shining.
VTT and German company ZAE Bayern have developed a solar-powered 10 kW chiller. This absorption chiller works in the same way as the gas refrigerators used in Finnish holiday cabins, for example. But in this case, a solar thermal collector is used instead of gas. The method requires electricity for the flow pumps only. If necessary, the chiller can also serve as a heat pump.
The results of the project showed that – to be used as a heating pump as well – an economically viable and competitive, solar-powered absorption chiller would need to be 50 kW or bigger.
Finnish company Savo-Solar Plc participated in both the planning phase and the practical tests. As a result, the company's head office was successfully cooled using the pilot system built for the project. Savo-Solar and ZAE Bayern aim to develop a commercial product which enables users to cut their electricity bills through cooling with absolutely no need for electricity. This would also reduce emissions.
