空气处理机组（AHU）作为一种空间加热和冷却系统，是住宅和第三产业建筑中最相关的能源消耗原因之一。由于空气处理机组的能效与气候条件密切相关，因此应特别注意不同地理位置每年不同的气候条件。本文提出了一种计算空调系统能效的方法，该方法根据空调系统的不同功能将空调系统的温湿度图划分为五个区域，每个区域的外部气候都有一个特定的状态，并给出了相应的权重。为了实现这一目标，室外气候参数（干球和湿球温度和湿度比）的不同组合被认为是定义区域的品种。将不同区域的空调机组能耗按相应的权重因子相加，即为全年总能耗。
Air Handling Unit (AHU), as a system for space heating and cooling is one of the most relevant causes of energy consumption in both residential and tertiary sector buildings. As the energy efficiency of AHU is closely linked to the climate conditions, a special attention should be given about varying yearly climate conditions in different geographical locations. This paper presents an approach for calculating the energy efficiency by using the Psychrometric diagram which has been divided into five zones based on different functions of AHU; for each zone outside climatic has a particular status with yearly weight that is corresponds for specific AHU’s operation. To achieve this, different combination of outdoor climatic parameters (Dry and wet bulb temperature and humidity ratio) has been considered as varieties for defining zones. Sum of AHU’s energy consumption in different zones based on related weighting factor will result in the total annual consumption of energy.
