Description

533 12.? dimensioneras För olika behov, varpå volym i ackumulatortankar, solfångarnas dimension och antal, samt antal aekumulatortankar kan varieras efter behov. Flera Ackumulatortankar och solfångare kan kopplas till gemensam turbin. 533 12.? dimensioned For different needs, whereupon the volume in accumulator tanks, the solar collector's dimension and number, and the number of accumulator tanks can be varied as needed. Several accumulator tanks and solar collectors can be connected to a common turbine.

Vätska väljs med omsorg så att temperaturområde från påbörjad uppvärmning till avslutad uppvärmning anpassas till solfångarens effektiva arbetsområde för aktuell geografisk placering av omvandlaren.Liquid is carefully selected so that the temperature range from started heating to completed heating is adapted to the solar collector's effective working range for the current geographical location of the converter.

I vissa applikationer, kan tryckutjämning erfordras mellan solfångare och ackumulatortank.In some applications, pressure equalization may be required between solar collector and accumulator tank.

Detta görs, för att underlätta påfyllning av vätska i solfångarsystemet. För att eliminera att gasbubblor stannar i rörsystemet installeras då rör mellan solfångarens och ackumulatortanken. Rör och ventil placeras så att gasen leds ut ur solfångarsystemet in i ackumulatorn. I dessa fall ska solfångarens översta del ligga i nivå med ackumulatortanken vätskenivâ.This is done to facilitate the filling of liquid in the solar collector system. To eliminate gas bubbles remaining in the pipe system, pipes are then installed between the solar collector and the accumulator tank. Pipes and valves are placed so that the gas is led out of the solar collector system into the accumulator. In these cases, the upper part of the solar collector must be level with the accumulator tank liquid levelâ.
