    The term ‘urban heat island’ refers to the localized increase in temperature associated with an urban area. The UHI is an example of unintentional climate modification when urbanization changes the characteristics of the earth’s surface and atmosphere. It was observed that the UHI effect might result in minimum urban temperatures being 5-6° greater than the surrounding countryside. In the case of London‚ mean annual temperature was 11°C‚ while the surrounding countryside was 9.6°C and the suburbs

    analyzed. An expression for the efficiency of the simple cycle is introduced. Theoretical analysis shows that strong and weak solution concentration limits play a decisive role in the value of cycle efficiency. S ystem efficiency with consideration of heat and work added to the system is well defined. The limits of regeneration temperature and mass of strong solution per kg of produced vapor are found highly dependent on the operating concentration of desiccant. Experimental results show that solution

    technology. The three most common OTEC systems are open cycle‚ closed cycle and hybrid cycle‚ all requiring all requiring a working fluid‚ condenser and evaporator within the system. These three systems all employ the thermodynamics of a working heat exchanger and use the temperature differences naturally occurring in the ocean as the driving force. A. Closed-Cycle D ’Arsonval ’s original concept formed the first closed-cycle OTEC plant system. This cycle uses a working fluid with a
