Résumé

From numerous perspectives, water is the ultimate choice of refrigerant. It is cheap and readily available; there is no contribution to global warming, no contribution to ozone depletion. It is non-flammable and nontoxic and there are no harmful atmospheric or fire breakdown products. This paper describes the result of the research with the objective to develop a commercial competitive chiller unit based on water as refrigerant. More than six years of research has resulted in the development of two sizes of a compact, low cost and high efficiency axial compressor for 0.8 and 1.8 MW cooling capacity respectively. The design and testing of the compressor and the direct type heat-exchangers has been performed at Danish Technological Institute. Based on the fundamental results a prototype commercial chiller has been designed, established and tested by Kobe Steel, who have the production rights along with Johnson Controls Denmark.
