摘要：

A centrifugal water vapor (steam) compressor has been developed for the high temperature range (90-110 degrees C) for industrial heat pumps in the 100-500 kW range with a 25-30 degrees C temperature lift per stage. The compressor is based on a highspeed gear from automotive turbochargers, thus allowing standard electrical motors for the driveline instead of the usual direct drive with expensive highspeed motors. The background for the development is an increased interest for high temperature heat pumps for various industrial applications, in particular in response to the general need of reducing fossil fuel consumption. There is a number of applications for the compressor. It can work as a direct steam generator as an alternative to standard boilers, and if operated in an open configuration along with a number of drying and concentration applications. In a closed configuration it can work as a general purpose high temperature heat pump.
