... of heat exchanger on system performance. For specified CO 2 /HC, optimal COP is obtained through global optimization of cycle pressures and mixture concentration. The heating performances of different CO 2 /HCs are compared, among which CO 2 /R600 and CO 2 /R600a behave better. Meanwhile, a typical vapor...

If a correction coefficient is found to be small after optimization, that coefficient can be neglected. Only the correction coefficients that cause a significant change to the final results (minimization...
