Samenvatting:
Significant energy saving is expected by using innovative heat pump concepts for removal and supply of heat from/to a separation process e.g. distillation systems. Conventional heat pumps provide limited temperature lift in an economical way. New heat pumps are required which can operate at the temperature levels of the distillation column and provide the desired temperature lift in one step. These heat pumps are presently not commercially available. At ECN a laboratory scale heat pump based on the thermoacoustic technology is developed. It matches the temperature conditions of a distillation column where the condenser temperature is in the range of 50-80°C with a temperature lift of 50°C. The heat pump is driven by a linear motor with an electrical power rating of 300 W. The experimental results of the heat pump will be presented.
