Solar installation and method for regulating the same

摘要

The invention relates to a solar installation for heating a heat accumulator or a circuit of a low-temperature heating system, having the following features: A primary and a secondary heat circuit are provided; A heat exchanger which connects the primary to the secondary circuit is provided; In the primary circuit, at least one solar module is provided. The invention is characterised by the following features: Means for controlling the mass flow rate of the primary circuit are provided; Means for controlling the mass flow rate of the secondary circuit through the heat accumulator are provided; A temperature sensor is provided in the primary circuit between solar module and heat exchanger; A further temperature sensor is provided in the secondary circuit downstream of the heat exchanger; A regulating device for regulating the mass flow rate of the two circuits as a function of the two temperatures measured by the temperature sensors is provided.
