Medium 2-kW System

In this case, the Sankey diagram is rather more interesting. The final output power is just 1.64 kW. Heat loss amounting to 1.8 kW is shown, together with 360 W of electrical loss being swept downwards. This 360 W is needed to drive the three blowers and pumps and to supply an electronic controller. 

This fairly complex high-power system uses compressors of the type discussed in Chapter 9 and various electrical subsystems discussed in Chapter 10. So we will use this system as a stepping stone to these later chapters. We will look in detail at an earlier version of this system in Chapter 11 near the end of the book, where we will use it as a
