Modelica Library for Building Heating, Ventilation and Air-Conditioning Systems
This paper presents a freely available Modelica library for building heating, ventilation and air conditioning systems. The library is based on the Modelica.Fluid library. It has been developed to support research and development of integrated building energy and control systems. The primary applications are controls design, energy analysis and model-based operation. The library contains dynami...
متن کاملEnergy-Smart Calculation of Thermal Loads in Mobile and Stationary Heating, Ventilation, Air Conditioning, and Refrigeration Systems
The energy consumption by heating, ventilation, air conditioning, and refrigeration systems forms a large portion of the total energy usage in buildings. Vehicle fuel consumption and emissions are also significantly affected by air conditioning. Air conditioning is also a critical system for hybrid electric vehicles and electric vehicles as the second most energy consuming system after the elec...
متن کاملAmerican Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE)
In a historic building with inadequate or no air conditioning or where it is not possible to install modern systems fitted with air filters, humidification, and controls, it is possible to mitigate the effects of temperature and humidity extremes on a building and its contents by controlling air-flow. When used in conjunction with mechanical air conditioning, this method can also save a little ...
متن کاملGray-box model for energy-efficient selection of set point hysteresis in heating, ventilation, air conditioning, and refrigeration controllers
Many heating, ventilation, air conditioning, and refrigeration systems operate using on/off controllers. A high and a low set point are selected above and below the desired temperature to command the refrigeration cycle to turn on or off when those temperatures are reached. In this study, exponential temperature correlations are used in a gray-box approach to provide information about the estim...
