3.5.13 Refrigerant R000
If the refrigerant used cannot be found in the list of refrigerants - see subsection 6.4.4 Plant – you can
select a user defined refrigerant designated R000 (the R000 designation does not refer to any known
refrigerant).
Before selecting R000 in the picture Setup/Configuration/Plant first enter the refrigerant curve data for
the refrigerant used in the picture Setup/Configuration/R000 :
Def. Refrigerant R000
Temp.: Press. (ABS):
-90 ° C/R 00.00 bar
-85 ° C/R 00.00 bar
-80 ° C/R 00.00 bar
... ...
80 ° C/R 00.00 bar
Table 31: Definition of refrigerant R000
For bar/ ° C, enter the pressure as absolute pressure in 1/100 bar. Enter a pressure value for each inter-
val of 5 ° C between -90 ° C and +80 ° C. Each pressure value in the picture must be given a certain value.
Pressure can be entered in the range between 00.00 and 99.99 bar. The table has been initialised to
00.00 bar.
When selecting R000, the calculation of the VI ratio is based on the R22 refrigerant table.
