Features two independent refrigerant circuits on all sizes. Steam from the outlet of the turbine will be passed through the condenser. As coolant enters from one side it flows to next end of the shell where all coolant gets mixed. This type uses both air and water to condense refrigerants. Higher is the fouling factor the lesser is the heat transfer. Corrosion resistant exterior paint that exceeds a 2,500-hour salt spray test. A modern automobile makes use of many more pieces of technology than used to be the case in the past. Hello Everyone! That means the refrigerant is not totally in a vapour state or totally in liquid phase. However, this may prevent you from correctly displaying the website and some parts of the site will not then work. CU1 CUS4 (3-13kW) So as a result due to this heat exchange, the water vapors temperature got reduced and it changed its phase from steam to liquid. Whoops! Condenser first de-superheats, changes its medium and then sub-cools it as per need.
