- captador solar de calor concentrado que puede proceder indistintamente de campos de heliostatos, concentradores disco-parabolicos o concentradores cilindro-parabolicos (60).- concentrated heat solar collector that can proceed either from heliostat fields, disk-parabolic concentrators or cylinder-parabolic concentrators (60).
Y donde el modo de operacion de de la PLANTA TERMOSOLAR CON CALOR CONCENTRADO INDIRECTO Y PROCEDIMIENTO DE OPERACION DE DICHA PLANTA TERMOSOLAR es tal que el fluido de trabajo (aire, helio o hidrogeno entre otros) es impulsado por medio del compresor (16), desde el enfriador del fluido termico de trabajo (13), hasta los intercambiadores de calor (32) (34) (36) y (38) siguiendo un orden tal que mientras las valvulas 3/2 (40) y (43) permiten el paso del fluido a los intercambiadores (32) y (38), las valvulas (42) y (14) permanecen abiertas para accionar el embolo (11) debido a la elevada presion de la camara A en comunicacion con el intercambiador (34) y permitir la evacuacion de la camara B a traves de la valvula (14) hacia el enfriador del fluido termico de trabajo (13). Cuando el embolo finaliza su carrera en sentido de izquierda a derecha, se cierran las valvulas (42) y (14) y se cambia el rol de las valvulas 3/2 (40) y (43) permitiendo el paso del fluido a los intercambiadores de calor (34) y (36), mientras que las valvulas (45) y (15)And where the mode of operation of the THERMOSOLAR PLANT WITH INDIRECT CONCENTRATED HEAT AND OPERATING PROCEDURE OF SUCH THERMOSOLAR PLANT is such that the working fluid (air, helium or hydrogen among others) is driven by means of the compressor (16), from the cooler of the thermal fluid of work (13), until the heat exchangers (32) (34) (36) and (38) in an order such that while the valves 3/2 (40) and (43) allow the passage of the fluid to the exchangers (32) and (38), the valves (42) and (14) remain open to drive the plunger (11) due to the high pressure of the chamber A in communication with the exchanger (34) and allow the evacuation of chamber B through the valve (14) towards the cooler of the thermal working fluid (13). When the stroke ends its stroke from left to right, the valves (42) and (14) are closed and the role of the valves 3/2 (40) and (43) is changed, allowing the fluid to enter the exchangers of heat (34) and (36), while the valves (45) and (15)
permanecen abiertas para accionar el embolo (11) debido a la elevada presion desde la camara B en comunicacion con el intercambiador de calor (36) y permitir la evacuation de la camara A a traves de la valvula (15) hacia el enfriador del fluido termico de trabajo (13). Este ciclo se repite de modo que en lugar de utilizar el calor 5 acumulado en los intercambiadores de calor (34) y (36) por medio de las valvulas (42) y (45), se utiliza el calor acumulado en los intercambiadores de calor (32) y (38) por medio de las valvulas (41) y (44).they remain open to actuate the plunger (11) due to the high pressure from chamber B in communication with the heat exchanger (36) and allow evacuation of chamber A through the valve (15) towards the thermal fluid cooler working (13). This cycle is repeated so that instead of using the heat 5 accumulated in the heat exchangers (34) and (36) by means of the valves (42) and (45), the heat accumulated in the heat exchangers is used (32) and (38) by means of the valves (41) and (44).
