Basic Heat and Mass Transfer complements Heat Transfer,whichispublished concurrently. Basic Heat and Mass Transfer was developed by omitting some of the more advanced heat transfer material fromHeat Transfer and adding a chapter on mass transfer. As a result, Basic Heat and Mass Transfer contains the following chapters and appendixes: 1.

I. THE HEAT PUMP REFRIGERATION CYCLE The Heat Pump is a refrigeration system like any other refrigeration system in that heat transfers from one place to another. For summer cooling, it can remove heat from occupied areas and transfer the heat to the outside air. When heat is needed, it reverses the action with a reversing valve and will remove .
