Advanced adiabatic compressed air energy storage (AA-CAES) system can effectively stabilize the fluctuations of new energy, and supply cooling, heating and power. This paper proposes an improved multi-stage AA-CAES system, in which a dual preheating structure is innovatively used between the expanders. And combined cooling, heating, and power (CCHP) model of AA-CAES system is proposed, in order to...
Hospitals require simultaneously different forms of energy such as thermal energy, steam, electricity and cooling. On the other hand, they suffer from the heat losses released by the incinerator, the medical air group and especially by boilers. The purpose of this paper is to illustrate some energetic problematics in Moroccan hospitals, and establish a novel configuration of a polygeneration system...
Distributed Generation based on CCHP systems offer the possibility to integrate several energy conversion technologies exploiting RES. However, integration increases the degrees of freedom number of the decisional variables for the minimization of both costs and GHG emissions. In this paper a multi-variable and multi-objective optimization model has been proposed and applied to the household sector...
In this paper the performance test results of a liquid desiccant air-conditioning (LDAC) system which uses waste hot water from combined cooling, heat and power system (CCHP) as driven heat resource have been presented. The supply air volume of the air-conditioning system is around 7000m3/h ~ 7500m3/h and its cooling capacity is about 60.43 ~ 95.74KW. It can maintain the supply air temperature under...
