Valentin Software's design program for heat pump systems has been expanded to support system designers, installers, and engineers. As before, air, brine, and water heat pumps can be calculated and simulated. Air, geothermal probes, groundwater, and geothermal collectors installed in the ground can be used as heat sources. In addition to the heat performance factor, the program calculates the annual energy yields and makes statements about cost-effectiveness and emissions reduction compared to conventional systems and presents all of the results graphically. These include the annual course of relevant temperatures, the useful heat and the electrical energy, as well as the weekly heat performance factor. When designing a system, the user can choose between various predefined system configurations including monovalent and monoenergetic systems with heat pump and solar thermal system, and bivalent systems with additional heat generators. New plants with a conventional backup heat generator can also be simulated and optimized. Heat generators can also be selected from a comprehensive database. After a simulation of the heat pump system with GeoT*SOL, an interface to PV*SOL, the simulation program for solar electric systems, can be used to determine the power supplied by the PV system directly to the heat pump system. This makes it possible to determine the degree of self-sufficiency of an existing energy supply for both the power supply and the heat supply of a building. The revised T*SOL storage tank database is now available in GeoT*SOL. There are over 600 products to choose from. Standard storage tanks can be used for a user's optimization and calculations, the volume and heat losses of which can be edited. As with heat pumps, collectors and boilers, certain storage tanks can be marked as favorites to be selected quickly and easily.
