Absorption systems have the potential of employing thermal energy such as waste heat to produce both chilled water and hot water for building cooling and heating applications. In the present study, a lithium bromide/water (LiBr/H2O) absorption system for cooling and heating applications was analysed on the basis of the first and second laws of thermodynamics. Simulation was employed to determine the coefficient of performance (COP) and the exergetic efficiency of the absorption system under different operating conditions such as the heat source, cooling water, chilled water, and supply hot water temperatures.

工业冷却水在电厂中虽然用水量小,但其涉及面广,且直接影响许多大型辅机的正常运转。在许多大中型电厂都没有专用的工业水泵。如果将工业冷却水并入其它系统中,停用工业水泵,既方便管理,又可节能降耗。本文谨将我厂改造实例供大家参考。 相似文献

This paper reviews the available worldwide cooling technologies for agricultural greenhouses and discusses the representative applications of each technology. Relevant information about the system characteristics, application and performance of the existing greenhouse cooling technologies such as ventilation (natural and forced), shading/reflection, evaporative cooling (fan-pad, mist/fog and roof cooling) and composite systems (earth-to-air heat exchanger system and aquifer coupled cavity flow heat exchanger system) is collected and presented in detail. As per the collected information, the pros and cons of each technology are also discussed. Finally, some important conclusions are drawn (based on the collected information) regarding the performance of each discussed system. 相似文献
