Résumé
This thesis is mainly arid areas of northwest large civil construction energy-saving air-conditioning , in-depth research . First, start with a special outdoor climate conditions from the Northwest , a careful analysis of the principle of direct contact with the heat and moisture of the air and water exchange , process and equipment , careful comparison of the Northwest Territories summer can take three air handling elect at room temperature program under the conditions of the most energy efficient and energy saving air conditioning system design , and finally through the comparison of the initial investment and operating costs in the three scenarios , come to the economic program of environmental protection and energy saving air conditioning . Under the special climatic conditions in the Northwest Territories , the air treatment program can be taken in the summer , based on the room temperature conditions different direct evaporative cooling , indirect evaporative cooling and indirect evaporative cooling and direct evaporative cooling combination of two evaporative cooling air treatment program . Through a careful analysis of the process , characteristics and principles of the three air-handling program , Jiuquan Region , for example, compare the three parameters of the program to determine the Northwest Territories summer special climatic conditions , the most energy-efficient air conditioning program is a direct evaporative cooling air treatment program , and this proposal design selection calculation of the air-conditioning system of a three - tier shopping centers in the Jiuquan region . Last through the initial investment and operating costs in the three scenarios , the consolidated total cost , lowest cost direct evaporative cooling air conditioning system , saving 150 million than the indirect evaporative cooling system than the secondary cooling system , saving 200 million , a considerable economic benefits considerable. Through the above comparative analysis , it can be concluded ; direct evaporative cooling air treatment program under the special climatic conditions in the Northwest Territories , is an economical and environmentally friendly energy - saving air-conditioning program .

Mots clés : Northwest Territories Environmental protection and energy saving Air conditioning program Direct evaporative
