In fact, some companies have suggested that the energy flow diagram be developed before the material flowsheet. ... 

Figure 4 is the energy flow diagram from the molecular system to the nuclear reaction system, and the key properties of the pool materials and the key parameters of the system are shown.

A refrigerator is a continuous cyclic device that removes heat from a low-temperature reservoir to a high-temperature reservoir at the expense of work input. The energy flow diagram of a refrigerator and its thermal reservoirs are shown in Fig. 1.2. Input work (W) is added to the refrigerator, desirable heat (Qf) is removed from the low-temperature thermal reservoir at Tl, and heat (2h) is added to the high-temperature thermal reservoir at Tu-...

Refrigerators and heat pumps have the same energy flow diagram and have the same components. A domestic air-conditioning and heat pump system as shown in Fig. 6.22 can, therefore, be used as a heat pump in the winter as well as an air-conditioning unit in the summer. Notice that both the domestic air-conditioning and heat pump system share the same equipment. Thus, the investment in the heat pump can also be used for air-conditioning to provide year-round house comfort control.

Energy Flow Diagrams. The chlor-alkali industry, like any electrochemical operation, is energy intensive. Therefore, it is instructive to determine how the eneigy is distributed over the entire process. This will indicate the most profitable areas for improvement.
