Compressor problems in ASPEN simulations of refrigeration cycles. .
Thread Content
In the refrigeration cycle, with all other parameters remaining constant, the compressor chosen is an isentropic compressor (with an assumed efficiency of 1), and the outlet pressure is set at the condensation pressure; the operation proceeds normally. Check the compressor operation results; do not set an outlet pressure. Instead, use the values of brakepower and other parameters related to power as the input for the compressor’s required power. Looking at the run results again, why is the loop parameter different from before? Especially at the evaporator outlet, the superheat of the refrigerant is very high. Why is that? Please ask the fellow sailors for help. Are there any ways to fix the compressor’s input power while still achieving the same operating results as before?
It would be better to include a document explanation; at least provide a picture
Hello, may I ask how to set the parameters of the compressor so that parameters such as outlet pressure and power can be variable rather than fixed?
