HVAC Library
Overview
The HVAC library allows the development and optimisation of large thermo-hydraulic Heating, Ventilation, and Air Conditioning systems.
It provides an optimum trade-off between simulation accuracy and simulation time, allowing to investigate the dynamic behaviour of building heating and cooling systems throughout a whole year.
Resources
The HVAC Library is a flexible and powerful tool to analyse different system layouts and compare
their primary energy consumption, their carbon dioxide emission or the energy costs with regard to any reference period (usually one year of operation).
Layouts with various heating and cooling generation devices can be analysed within only few minutes and compared for cost reduction.
Different concepts of heat recovering or humidity control can be modelled, simulated, analysed and compared from different points of views.
It is possible to model the thermal behaviour of buildings and its interaction with the heating and cooling system thanks to transient simulations.
- Air ducting
- Adiabatic and steam humidifiers and water extractors
- Borehole heat exchanger
- Absorption- and vapor compression chillers
- Evaporative and dry cooling towers
- Boilers and combined heat and power
- Heat pumps
- Heat exchangers (liquid and air side)
- Radiators and floor heating (compatible with HumanComfort)
- Heating and cooling consumers
- Solar panels
- Domestic hot water storages and tanks
- Pipes, valves and manifolds
- Pumps, blowers and fans
- Controllers
- Automatic energy balances
- Different fluid models for heating and cooling systems
In addition, a weather package is provided to read in the weather data, such as temperature, humidity and irradiation.
The package is based on and fully compatible with the weather package of the HumanComfort Library. The full version of the HumanComfort Library offers i.a. building models which can be simulated together with the HVAC system to generate heating or cooling loads from the transient building behaviour.
The library can be used together with the HumanComfort library to model HVAC systems.
