BITZER adds R515B to BITZER software
R515B was designed as a replacement for R134a for use in medium temperature applications, comfort air conditioning, heat pumps, process air conditioning and process heating. BITZER has now implemented the refrigerant in its BITZER software: screw compressors from the CSH series can be used with R515B from software version 6.15.2. R515B is also already included in the Refrigerant Ruler app from BITZER.
Made of 91.1 per cent R1234ze(E) and 8.9 per cent R227ea, R515B as a A1 safety refrigerant is classified according to DIN EN378-1 and has been graded as being neither toxic nor flammable. In terms of thermodynamics, R515B reacts similarly to pure R1234ze(E). The R227ea it contains suppresses the flammability. The refrigerating capacity and performance statistics are, however, almost the same as pure R1234ze(E).
With a GWP of 299, R515B has a global warming potential that is 80 per cent less than that of R134a. R515B is therefore particularly interesting for screw compressor applications for which R134a was being used until now and which can not be changed to use flammable, low-GWP refrigerants such as R1234ze(E) or R1234yf for the most diverse of reasons.
With the BITZER software, BITZER offers users a reliable instrument for selecting suitable components for their respective systems. Its newest update makes it possible to calculate performance data for even more components in the BITZER product range. Users can access the BITZER software online (www.bitzer-software.com) or download it directly for use offline (https://www.bitzer.de/shared_media/files/BitzerWinSetup_6-15-2-2501.exe).
