View Full Version : Heatpump up to 100C

28-06-2002, 07:59 AM

I have a project to create a heatpump with following details:

Heating capacity 1500 kW
Evaporator temp. Water 30 to 10C
condenser Water 73 to 85C

The refrigerant R114 is forbidden, so what is the best refrigerant for this application?
I have heard about R236FA, but have no data sheets!

At first I thought about a screwcompressor with R134a but there are limits in pressure. Pistoncompressors (40 bar from York) are n ot released for R134a.
What would be the best compressor, perhaps a turbomachine?

Is there another process possible instead of the normal compressor process?

Have somewhere names of companies who have installed some system allready. (Location is germany!)

Best thanks for your help.

We make systems that operate in this range.
