Software programs for thermodynamic systems modelling and simulation, e.g. Polysun ® , are well established and widely used. By comparison, there are few tools available for the dimensioning of pipe networks, pumps and expansion vessels. Furthermore, it has not been possible to prove operational safety numerically. This gap is closed by the software tools HYDRA and THD which are introduced in this article. HYDRA is used to design the pipe network of large thermal solar plants. THD allows the dimensioning of solar plants up to approximately 100 m 2 collector area, including proof of venting capabilities and proof of stagnation safety.
