The Heating, Ventilating and Air Conditioning (HVAC) library, developed by XRG Simulation GmbH, supports the design and performance optimization of complex thermo-hydraulic HVAC systems.

This library provides an optimal compromise between the accuracy of the simulation results and the calculation times for getting the dynamic behaviour of the modelled HVAC systems; this represents a feature particularly suitable for simulating the system operations over an entire year and therefore estimating the impact of the design choices in terms of operating costs.

For a more meaningful analysis, models can be interfaced with those of the HumanComfort library in order to study the interaction between the building environment and the heating/cooling systems and derive effective and efficient control strategies.
