Formatted Abstract/Summary
Since only arid and semi-arid areas are more suitable for concentrated solar power (CSP) production, dry cooling may offer the only effective alternative for CSP plants. However, reports showed that dry cooling installed in trough solar plants in hot deserts reduced annual electricity production by 7% and increased the cost of the produced electricity by about 10%. To address the performance problem of dry cooling used in CSP plants, inlet air pre-cooling was proposed and will be tested by the Queensland Geothermal Energy Centre of Excellence (QGECE) in cooperation with the Australian Solar Thermal Research Initiative (ASTRI).

To avoid corrosion, scaling and fouling on heat exchanger bundles, the inlet air pre-cooling is required to evaporate all water to avoid any water droplet on contacting with the heat exchanger surface. Special spray nozzles /wet media are to be identified to meet the requirements of fully evaporation by the experimental study. All tests will be conducted in QGECE’s wind tunnel to optimise the nozzles/wet media selection and the cooling system configurations to achieve the best performance of CSP plants. Equipped with this wind tunnel are various temperature, humidity, wind speed, pressure and flow rate sensors. PIV and PDPA are used to investigate the water evaporation process and flow dynamic. This paper presents the wind tunnel facility as well as its instrumentation for inlet air pre-cooling research.
