Use the sliders to set the enthalpies of the refrigerant at the four principal points in the cycle. Weboutlet of the condenser (point #3 on the chart). In the real world, some subcooling would be expected at the condenser outlet. Subcooled liquid provides insurance against liquid flashing as the refrigerant experiences pressure losses in the tubing and components. The refrigerant is in the liquid state now, and at a high pressure and temperature. http://web.mit.edu/10.213/www/psx/ps99/8/8sol.pdf 07帽徽
