Sažetak
Contemporary trends in Western countries show that small cogeneration plants are not only preferable energy and environmental solutions, but also economically excellent ones. Application of cogeneration in large, medium and nowadays even small heating, ventilation and air conditioning (HVAC) plants, is becoming common in modern systems. The article deals with the basics of the cogeneration HVAC systems, considering reciprocating engines in conjunction with heat exchangers and absorption chiller. Described system is analyzed in a view of key energy, ecology and economy correlations. Moreover, an introduction of recently popular micro-cogeneration for small HVAC system is given. Since construction of cogeneration HVAC systems could often be linked with the practical problems or even barriers, particularly when compared with installation of conventional system, some of these major problems are also described. Finally, these theoretical considerations of cogeneration HVAC systems are integrated with an example found in one hospital in Croatia. This example illustrates main technical and economical characteristics of such system on real site. As a conclusion, the article introduces guidelines to contemporary energy management trends as a function of power, heating and cooling energy production. It explains that cogeneration HVAC systems are viable not only from the technical point of view, but also from the economical one.
