Abstract: The energy saving is even more significance for China''s modern construction. With the rapid development of national economy and the improvement of people''s living standard, the application of HVAC(heating ventilation and air conditioning) is in increasing popularity, which greatly improves the people''s environment of production and life. However, the energy consumption problems is also appeared. In order to create a comfortable living environment, building comfort air-conditioning system has been widely used. This paper expounds the energy saving design and its related questions of energy saving technology of HVAC(heating ventilation and air conditioning).
Keywords: HVAC(heating ventilation and air conditioning); energy saving technology

随着社会的发展城市房屋的建设和城镇化的快速步伐,建筑能耗在总能耗中所占的比例越来越大,给建筑能耗带来了巨大的压力。而目前我国建筑能耗水平不允许按照城市建设和城市化的节奏增长,建筑节能势在必行。这不仅具有巨大的经济和环保意义,同时也有国防战略意义。而在建筑能耗里,用于暖通空调的能耗又占建筑能耗的30%一5O%,且在逐年上升。随着人均建筑面积的不断增大,暖通空调系统的广泛应用,用于暖通空调系统的能耗将进一步增大。这势必会使能源供求矛盾的进一步激化。
一、暖通空调系统的节能设计
1.1改善暖通空调系统的设计
空调系统的设计原则:一保证各个房间(楼梯间除外)的室内温度能独立调控是供暖系统的首要; 二是便于实现分户或分室(区)热量(费)分摊的功能; 三是管路系统简单、 管材消耗量少、 节省初投资。暖通空调系统特别是中央空调系统是一个庞大复杂的系统,系统设计的优劣直接影响到系统的使用性能。……
