Intelligent Control Systems of the Air-conditioning for the Purpose of Achieving Energy Efficient Exploitation Regimes in the Complex Operating Conditions

The project includes a series of phases and activities through which the implementation of the project is going to be done, including: construction of a new laboratory for air-conditioning installation for testing and verification of the control algorithms in complex conditions of exploitation, when the system dynamics changes considerably: development of the software tools for the air-handling unit control, in order to minimize energy consumption for heating, cooling and ventilation; development of the software solutions for data exchange between different protocols (Profinet, KNX, Modbus, Profibus), between the air handling units, chillers, boiler plants and electrical network analyzer. The laboratory installation will be constructed in a way to provide different operation modes, such as: the use of waste heat, drying and moistening the air, adiabatic cooling, free cooling, the working regime in the mode of heat pump, varying the flow rates of fresh air depending on the ventilation needs and external conditions, the use of the return air, operation mode with variable air flow rate. Monitoring and control of the indoor air parameters is also included, in order to ensure the required level of thermal comfort. Testing the application of passive measures to reduce energy consumption for cooling is also included, such as the application of the natural night ventilation and the window’s shading. Also, CFD flow models are going to be carried out for various air flow rates.
