Cooling Tower and Water Saving:
-The climatic study was the basis for the work related to the improvement of cooling tower concepts. As a result of the cooler tower study it can be stated clearly, that considerable water savings can be achieved by using proper combinations of cooling towers readily available on the market without using expensive hybrid cooling towers. The relative size of the wet and dry parts of cooling tower as well as the mode of operation can be determined with a model for various sites and buildings.
Refrigeration cycle improvement:
-An important development is related also to the refrigeration process itself, where the integration of supplementary internal heat exchanger can improve the efficiency of the cycle by more than 10% in addition to an improvement of the efficiency of energy recovery from the flue gas which in total allow to design direct fired chillers with a COP 1,25-1,30 instead 1,0 to 1,1 of units already on the market.
New Direct Fired Generator:
-The new regenerator and the newly introduced economizer has been tested thoroughly on a semi-industrial scale (350 kW). The generator has precisely met the predicted performance and has shown very good and stable operational results which allow industrial implementation with only limited risk for scale-up in larger installations.
The research work performed within the frame of this research contract was successful and the objective could be reached by a joint effort of all partners.
After critical review of the development work, it can be stated clearly, that the development of a new environmentally friendly absorption chiller technology has led to an almost immediately marketable product. With the results of this research contract, the partners will be able to build a an absorption chiller with a number of new features:
-Very high COP based on lower calorific value of the gas.
-Low water consumption due to high COP ( less heat to be dissipated ) and the new cooling tower configuration which , in combination with a new regulation scheme can operate as dry system for relatively long period of time throughout the year.
-Due to low inventory of solution the chiller can respond quicker to load variations, this may also eliminate cold storage tanks etc.
-The design of the generator is very flexible and can be adapted to a large number of installations with various heat sources, e.g. direct firing, use of flue gas form gas engines and gas turbines.
-The design can be used in an industrial demonstrator plant immediately if the size is limited to approx. 1-2 MW in order to limit technological risks when scaling up.
