Further development of an existing adiabatic dewpointcooler by characterising the thermal and electrical performance. The design was optimised by adjustment of the heat exchanger size and the geometry of the primary and secondary air channels.

This water based air conditioner was mounted in the Re/genT laboratory. The energy consumption, cooling capacity, water use, airflows, air pressure losses and various temperatures and relative humidities were measured to characterise the performance. Tests were operated at many environmental conditions (different temperatures and humidities) to map the performance at different operating conditions. Based on the measurements a theoretical model was created, predicting the energy use, cooling capacity and water use. The dimensions of the heat exchangers and it channels were input parameters of the model. With the model the design was improved and sequently retested. As a result of this investigation an improved heat exchanger design was created against reduced production costs.
