Abstract. Solar energy can be utilized as the energy source for many high quality processes operating at temperatures above 100 oC. The efficient conversion of solar radiation to these temperature levels into the heat requires the use of concentrating or evacuated solar collectors. In this paper, a concept of solar receiver prototype (marked as CPC-2V) is described for area of middle temperature conversion of solar radiation in heat. The prototype has high efficiency, low price, possibility of its production in small and middle companies, and wide distribution. Its application in a good part of year (or entire year) would mean significant savings of electric energy which is now used for preparation of warm water, and in central and long-distance heating systems.
Key Words: energy source, solar radiation, solar energy concentrator, prototype.
PROTOTIP PRIJEMNIKA ZA SREDNJETEMPERATURNU KONVERZIJU SUNČEVOG ZRAČENJA U TOPLOTU
Visokokvalitetna sunčeva energija može se koristiti kao energetski izvor za mnoge radne operacije na temperaturama iznad 100 oC. Efikasna konverzija sunčevog zračenja u toplotu, na tim temperaturnim nivoima, zahteva korišćenje fokusirajućih ili fokusirajuće vakuumiranih prijemnika sunčeve energije. U ovom radu je predstavljen koncept solarnih prijemnika (označen kao CPC-2V), za oblast srednje temperaturne konverzije sunčevog zračenja koji ima visoki učinak, nisku cenu, mogućnost proizvodnje u malim i srednjim preduzećima, široku distribuciju, sa jasnom težnjom da se njegovom primenom u velikom delu godine ili celogodišnje ostvare značajne uštede električne energije koja se sada koristi za pripremu tople potrošne vode i u sistemima centralnog i daljinskog grejanja.
