Renewable sources for 100 per cent carbon neutral operation for CSH screw compressors
Using electricity from renewable sources, electrically powered heat pumps now offer 100 per cent carbon-neutral operation: thanks to their expanded application limits, BITZER CSH screw compressors can do it all in the extensive capacity range for process and district heating. They allow OEM system manufacturers to design next-level industrial heat pumps with a water-leaving temperature of up to 85° C. The capacity range of the approved CSH screw compressors extends from approximately 250 kW to around 1,000 kW heating capacity at 35 °C evaporation and 80 °C condensing temperature in economiser operation with the refrigerant R1234ze(E). With its expanded application limits, the CSH series can now be operated with the refrigerants R134a, R513A and R1234yf at an evaporation temperature of up to 30 °C and a condensing temperature of up to 80 °C. With R1234ze(E) and R515B, it can even reach an evaporation temperature of up to 40° C and a condensing temperature of up to 93° C.
Compressor technology for heat pump manufacturers
BITZER has developed the expanded application limits on the basis of laboratory measurements and series of tests with selected partner companies in recent years.
The qualified selection of BITZER CSH screw compressors provides heat pump manufacturers with the compressor technology necessary to develop and produce large-scale, high-performance commercial and industrial heat pumps. The new application limits are currently being integrated into the BITZER software. If users require assistance with calculation, they can get in touch with their BITZER contact.
