Testing of solar thermal and air-dehumidification systems
SERIS operates well equipped laboratories and outdoor facilities on solar thermal technologies. Presently the R&D focus is on solar powered air dehumidification.
The laboratories are equipped with high precision instruments for temperatures, flows of liquids and gases, pressure, air-humidity, solar radiation and other relevant meteorological parameters. Detailed and comprehensive data logging as well as data evaluation is operational. Based on these installations and capabilities SERIS offers the following services to industry and R&D institutions:
Solar thermal collectors, testing and analysis Determination of the collector efficiency as a function of (i) solar irradiation, (ii) difference between collector temperature and ambient temperature and (iii) angle of incidence of solar radiation |  | |
Solar thermal systems, testing and analysis Solar thermal collectors can be tested in combination with heat storage installations resulting e.g. in information of solar system efficiency. Heat energy storages can be simple hot water tanks, stratified water tanks or phase change (latent heat) storages. Thermal energy output of the solar system can be simulated through a temperature controlled heat exchanger dummy load. Presently systems up to 10 kW average thermal output can be investigated. |  | |
Air dehumidification units, testing and analysis The performance of such units can be analysed as a function of temperatures, air humidity (inputs and outputs) and flow rate. Presently only smaller systems with flow rates of up to 110m3/hour can be analysed. Extensive modelling and simulation services are offered in order to assess the operation of the dehumidification unit in the context of complete air-conditioning systems. |  | |
