Heating Center Planning and Optimization

With Polysun, you can simulate and compare different generator variants, and test the control strategy virtually before construction begins.

Heat pump sizing

Simulate heating load and building demand to find the optimal heat pump configuration for efficiency and cost-effectiveness.
energy districts can be simulated easily in Polysun

District Energy

Heat network simulation enables accurate design and sizing. Modeling allows different scenarios to be considered and the effects of different operating configurations and environmental influences to be predicted. This leads to better use of resources and increases the efficiency of the overall district energy system.

PV System Design

Design PV systems in 3D, size inverters and batteries, and calculate yields based on real weather data with Polysun.

Solar Thermal Systems

Key factors include the type and area of collectors, hydraulic integration, required flow temperature, and buffer storage sizing.
