干旱区生态环境知识资源中心

In these recent thirty years, several investigations have been encouraged and done about the environment improve and the enhancement of the energy efficiency. In some arid areas, an important agrarian activity is developed because the fecundity of the soil and the presence of an important underground reservoir of water. The fruits production is important and must be stored for few months before its delivery to consumers. In order to protect the production some cold rooms have been constructed for more than 30 years, They need to be renewed. The extracted water is hot and must be cooled for its use in irrigation. This work is concerned by these two topics; renewing the cold rooms as recommended in Kyoto protocol and use of heat recovered from that released by the hot water. Fur this purpose an absorption refrigeration process is adopted using a not prohibited refrigerant and waste heat recovered as energy source. A reduced cold room is designed for theoretical simulation and experimental tests. Calculations and results are presented and discussed.
