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

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.

Chapter 18 Vocabulary • Energy Efficiency- Percentage of the total energy input that does useful work and is not converted into low-quality‚ usually useless heat in an energy conversion system or process. See energy quality‚ net energy. • Incandescent Light Bulb- One largely used devices that uses large amounts of energy‚ wastes 95% of its energy input of electricity • Internal Combustion Engine- Another device that uses a lot of energy‚ wastes 75%-80% of the energy in its fuel • Coal-Burning
