Solar cooling: a new Field for Simulations

Submitted by Baerbel Epp on February 24, 2009

Solar cooling is a promising new field of application for solar thermal technology. A new version of the simulation software Polysun will be published in April. It will not only be able to design solar thermal systems but also solar powered cooling plants that work with compression coolers or fan coils. A version that also contains a simulation model for absorption chillers is scheduled for the summer months. Polysun is offered in Chinese, Czech, English, French, German, Greek, Italian, Portuguese and Spanish.

Cupori Group brings out cleaner copper tubes

Submitted by Baerbel Epp on September 17, 2008

The Finnish company Cupori Group Oy, which in the spring took over the copper business of Outokumpu Copper Tube, now supplies a copper tube with a particularly clean surface. At the Intersolar 2008 in Munich in June the company presented its new “Tub-e” copper tubes, although still under the old name. They are claimed to have a particularly clean surface thanks to a thermal cleaning process. According to Cupori, welding times during absorber manufacture are shorter with the new tubes.
