摘  要:分析了下送风房间空调负荷的特点,指出了下送风空调系统与传统空调系统在负荷计算方法上的差异,介绍了2种目前用于下送风空调负荷计算的主要方法即数值计算法和修正系数法,并对2种方法的计算特点、适用范围等进行了详细论述。数值计算法是一种可精确求出下送风房间空调负荷的计算方法,但是过程较繁琐,计算量较大,需借助专门的软件才能实现。在进行发热量密集车间下送风负荷计算时,应优先考虑采用整体修正系数法。The characteristics of air conditioning load in the underfloor air supply rooms were analyzed, and the difference between un- derfloor air supply air conditioning and the traditional in load calculation method was pointed out. Two main methods which are used to calculate air conditioning load in underfloor air supply rooms were introduced, and the characteristics and application scope of the two methods were described. Numerical calculation method can exactly calculate the air conditioning load in underfloor air supply rooms. Because of complicated process and great magnitude, the calculation can be achieved only by virtue of professional software. Revised coefficient method should have a priarity to be adopted when calculating air conditioning load in underfloor air supply rooms of deuse heat radiation.
