Reply to 3# Robert_Gong: Could you upload the bkp? It seems difficult to set the outlet temperature and pressure simultaneously

Reply to 4# longkui1990: There is a setting for the heat exchanger within the compressor module; enter 100C in the aftercooler field.

Reply to 4# longkui1990: You can just use a heat exchanger. If power consumption is required, a compressor and heat exchanger are used.

The problem is simple: first check the mass flow rate, then switch to the required conditions and check the actual volume flow rate – that’s all. . .
