What we do
The Division of Building Services Engineering focuses on training and research into the indoor climate, energy use and technical systems that supply buildings and bring them to life: in other words the ventilation, heating, cooling and various types of energy supply systems.
The Building Services Engineering test hall is the only one of its kind in Sweden. It is designed to enhance knowledge of the way in which climate control, comfort and indoor environment systems operate in different circumstances. The facility provides a clear insight into the entire process from energy supply, distribution and control through to the resulting indoor climate and provides a wide range of options for various types of research and/or training.
The test hall has a number of different systems, rigs and chambers:
- Filter test rig
- Ground storage system with nine individually adjustable boreholes
- Liquid-borne distribution system for heating and cooling
- Central control and monitoring system for both the control and collection of measurements
- Various laboratory rigs for experimenting on pumps, refrigeration systems, control and regulation systems etc.
There are also a number of test chambers for studying the indoor environment:
- Clean-air chamber for analysing emissions from humans and materials
- Metal-lined chamber (an enclosed space with sheet metal walls for analysing emissions from various materials)
- Glass room (an enclosed space with a wet bench and large ceiling-mounted filter unit for laminar ventilation)
- Seminar room for analysing air quality and thermal comfort.
The test hall’s seminar room measuring 33 m² is designed for maximum flexibility and can be heated, cooled and ventilated in several different ways. Many different types of studies can be carried out here into energy use, control, thermal comfort and air quality. The seminar room can be converted into a meeting room, training area or even a living room and can also be screened off to create a smaller room equivalent in size to an office. The room is equipped with four “intelligent devices” supplying air to the room and the same number of air extraction devices. Each device can be individually regulated and controlled for presence detection, temperature or CO2.
The seminar room is equipped with a ceiling-mounted fan convector for heating or cooling, underfloor heating/cooling and a network of radiators. In connection with an ongoing research project into thermal comfort and controllability in heating and cooling systems, the room has also been equipped with cooling baffles in the ceiling.
Distribution system – the test hall’s “bloodstream”
The liquid-borne distribution system runs, like a bloodstream, through the test hall. It is supplied from a ground storage area, heat pumps, cooling machinery, a boiler and accumulator tanks in three different pipe networks with three different temperature levels. The system is designed to facilitate the connection of various test rigs as heating or cooling is required. It is also equipped with various controls and sensors connected to the central control and monitoring system which, like the distribution system, can be described as the test hall’s nervous system.
The importance of transforming theoretical knowledge into practice
The ability to visualise actual systems, components and processes is a fundamental aspect of the development of engineers’ technical understanding, encouraging their interest and creativity. Being able to see fully functioning systems and perform full-scale experiments provides a much stronger sense of reality and practical experience than fundamental theoretical principles and simulations performed in a computer environment can provide. Their interest and, especially, their enthusiasm increase significantly! This applies not only to students at university but also to engineers who are already working in the sector, who want to develop their expertise or quite simply update their knowledge.
Existing test rigs include:
- Control test rig (adjustment of P, PI or PID to achieve the required flow or temperature)
- Pump rig (importance of static pressure, influence of pump and system characteristics)
- Flow measurement rig (various means of measuring air flow)
- Filter test rig (measuring separation efficiency depending on filter and/or ionisation)
- Radiator rig (effect of adjustment, pressure drop, flow and temperature on heat output)
- Refrigeration rig (generation of electricity, heating and cooling effect and COP).
How can we collaborate?
Our aim is to develop solutions and skills which result in good indoor environments, while also ensuring that the impact on the exterior environment is as limited as possible. We can offer the following services to companies or organisations that need assistance in the field of building services engineering:
- Measurement assignments
- Laboratory tests
- Practical tests
- Training and education, experimental and laboratory work
Project assignments and initiatives are developed and implemented in close collaboration with our clients.
