This book presents the modeling of a winter air conditioning system using a concentrated collector. A modular computer program has been developed for the winter A.C. system to simulate various configurations with the help of weather data of Bhopal India. The effects of hot water inlet temperatures on the coefficient of performance and the surface area of the absorption cooling component are studied. Also studied the impact of the reference temperature, which is the minimum allowable hot water inlet temperature on the fraction of total load, met by non-purchased energy. The methods are based on the model predictive control scheme and simulation. Definition and control of indoor conditions for reaching thermal comfort in buildings are hard to be established. Thermal comfort has a significant influence on the productivity and satisfaction of indoor building occupants. The majority of heating, ventilation and air conditioning (HVAC) systems for thermal comfort hence results showing the proposed methodology regarding both thermal comfort and energy savings.

Zinc-based alloys have emerged as a potential material system to substitute the cast irons as well as various non- ferrous alloys in the mentioned category of applications involving especially sliding wear conditions on a cost-economic basis. The book presents the sliding wear response of a zinc-based alloy reinforced with SiC particles over a range of applied load, sliding velocities, and test environments. The wear response of the matrix alloy and the composite was compared with that of conventional grey cast iron. Through such through investigation, herein we have successfully shown that the better endure efficiency of our developed of zinc-based composites over the conventional zinc-based alloy and cast iron in the sliding wear applications.
