Preface
Heat pumps are a quite effective means to look forward to the enhancement of energy efficiency and savings. It is a very broad subject, and therefore, it is almost impossible to include all the related features in a unique volume. Far from being exhaustive, this volume is aimed at providing a detailed overview of the main topics that any professional needs to know, before either employing such machines in his designs or evaluating their energy performances. After a general description of the world market, the thermodynamic basic principles of heat pumps are recalled, emphasizing the effects of the internal and external irreversibilities on the heat pumps’ performances. The main components are analyzed, also concerning their reciprocal interactions and those with the thermal environment they are in contact with. In fact, heat pumps are complex systems which, in turn, interact with other complex systems constituted, on the one hand, by the indoor environment (internal source) and, on the other, by the outdoor e
