The state of art for water vapour compressors and cooling plants using water as refrigerant.
Author(s) : MADSBOLL M. S., MINDS G., NYVAD J., ELEFSEN F.
Summary
The paper describes the current level of practical use and ongoing research into cooling and heat-pump plants using water as refrigerant. The paper focuses especially on the experience with a 2-stage cascade heat-pump plant in Denmark that has been operating since 1986. The lower stage uses water as refrigerant and produces vacuum ice. The upper stage is a traditional R12 heat-pump plant. The cooling capacity is about 1 megawatt. Test results are also presented for operation of a cycloid compressor for water vapour. Finally, a current demonstration project and the expectations of future development within the area are described.
