Abstract
Most thermal engineering problems are solved at sufficient accuracy by second law analysis of either steady state or control mass models. However problems with transient or periodic changing conditions pose also challenges. Changes in environmental conditions may influence thermal performance of energy conversion systems positively or negatively [1-4]. Shifting greater load of system to times with favourable environmental conditions, e.g. in power plants to times with low environment temperature, can increase daily average thermal efficiency. This lecture concentrates on the effects of variation of environmental conditions and of demand, utilising recently obtained results [1,2].
