18 Component Test: Indirect Evaporative Cooler A1 WÜ1 A2 VK2 WÜ2 A3 A4 Results Wetted area provides good evaporative cooling Only 15 % of the heat transferring area are wetted (meets expectations)
19 Component Test: Absorber 22 C 30 C Results Air dehumidification is almost isothermal. In first performance tests, only 50 % of the dehumidification aimed at was experimentally reached. Realized Energy Storage Capacities: kwh/m³
20 Summary and Conclusion A demonstration plant for the state of the art of liquid desiccant cooling has been built up. The jazz club can be cooled. The performance of the controls and the measurement accuracy is good. The plant has proved to be an excellent facility for performance tests of the components absorber, regenerator and indirect evaporative coolers The performance of the indirect evaporative cooler and the fan coil units is close to what has been expected. In the first tests, the absorber-regenerator-unit did not yet achieve the intended performance. The wetting of the exchange surfaces (20-40 %) of the tested, commercially available devices is far below what has been reached in laboratory (> 90 %). An improvement in surface wetting would be a major step towards favorable economics of this technology.
