Re: [TRNSYS-users] Nigh time spray radiant cooling

A good starting place appears to be a publication from 1987 done by S. Somasundaram, Assistant Professor of Mechanical Engineering at Texas A&M University, titled, “AN EXPERIMENTAL AND NUMERICAL MODELING OF A ROOF-SPRAY COOLING SYSTEM”. Doing a google search of that title brings up a link to the article that goes into theory detail, along with other publications that refer to at least one former manufacturer of such systems.

Subject: [TRNSYS-users] Nigh time spray radiant cooling

Has anyone modeled a nighttime radiation cooling system, where the water is sprayed directly on the rooftop of the building, not through tubing/flat plate collectors? If so, any ideas on how to model this in TRNSYS/Excel?

Any information on the theoretical background would also help. I can only seem to find information regarding closed systems.

thanks
