摘要
以长沙某办公建筑为例,计算了建筑空调负荷,结合多联机厂家提供的修正系数进行设备选型,并计算了多联机设备选型容量指标。结果表明,多联机选型计算容量指标远小于工程实际应用容量指标,理论计算不能指导实际设计选型。对比分析了多联机选型计算容量指标与传统水冷空调选型容量指标。
Taking the office building in Changsha as an example, calculates the cooling load. Selects the equipments based on the correction factors provided by VRF manufacturers and calculates the capacity indexes of VRF equipments. The results show that the calculated capacity indexes are far less than practical capacity indexes. The theoretical calculations are unable to guide the equipment selection during the practical design. In addition, compares and analyses the calculated capacity indexes of equipment selection in the VRF system and the traditional water cooled air conditioning system.
