- Abstract
- A large amount of the operating costs of a building is determined by the energy
requirements and the fuel consumptions of its heating, ventilation and air conditioning
system (HVAC-system). Simulation programs are used to determine the energy use in
buildings. These simulation programs are based on models for the type of HVAC equipment
used and models for determining the internal and external loads of the building. In this
project a model for rooftop packaged air conditioning units has been developed.
The model uses generally available manufacturer's catalog data information to
determine the model parameters. Thus, the model is easy applicable. The system is modeled
by describing the performance of each component with mechanistic models. This method has
been successfully used to predict the performance of rooftop packaged air conditioning
systems and allows certain extrapolation of performance data.
The model has been developed with the Engineering Equation Solver (EES) software
package. A program has been written that allows determining the characteristic model
parameters based on manufacturer's performance data and also allows creating extrapolated
performance data for different operating conditions. Originally developed with EES the
program can be also called directly by TRNSYS, a transient simulation program.
