3D thermal climate monitoring in factory buildings

Guaranteeing defined conditions, such as the temperature levels inside the factory's building shell, is often important to produce high-quality products. Heating, ventilation and air conditioning (HVAC) equipment, as part of the technical building services, is energy intensive and accounts for a major share of the factory's energy demand. For an...

A framework for simulation and control of hybrid energy networks

For the built environment it is envisaged that in the next decades the total annual energy demand, both thermal and electric, could be covered by renewable sources generated within the built environment. An increasing number of thermoelectric elements, such as heat pumps and thermal storage, will enable conversion from heat to electricity and...

Multi-agent control for integrated heat and electricity management in residential districts

For the built environment it is envisaged that in the next decades the total annual energy demand, both thermal and electric, could be covered by renewable sources generated within the built environment. More and more thermoelectric elements, such as heat pumps and thermal storage, will enable conversion from heat to electricity and vice versa....

Localized climate control in greenhouses

Strategies for controlling the indoor climate in greenhouses are based on a few sensors and actuators in combination with an assumption that climate variables, such as temperature, are uniform throughout the greenhouse. While this is already an improper assumption for conventional greenhouses, it especially does not hold for the new trend of...

Applications of virtual sensors in three-dimensional, broadband active noise control and the effects on the quiet zones

This paper presents various experimental results of a real-time, multiple-channel, broadband Active Noise Control (ANC) system, employing the Remote Microphone Technique (RMT) as virtual sensing algorithm in different settings. The effects of virtual sensing on the shape and size of the quiet zone are experimentally investigated. To enhance the...

Virtual sensors for local, three dimensional, broadband multiple-channel active noise control and the effects on the quiet zones

In this paper, two state of the art virtual sensor algorithms, i.e. the Remote Microphone Technique (RMT) and the Kalman filter based Virtual Sensing algorithm (KVS) are compared, in both state space (SS) and finite impulse response (FIR) implementations. The comparison focuses on the accuracy of the estimated sound pressure signals at the...
