传统分体式家用空调器的性能在很大程度上取决于蒸发器盘管上是否有足够的空气流量。要在显冷量和潜冷量之间实现适当平衡，需要有足够的空气流量。典型的目标空气流量约为每吨冷却能力350至450立方英尺（581至747升/秒/千瓦）。测量了佛罗里达州27个装置中穿过盘管的气流。气流罩法和条带热阻法均采用既定方案测量空气流量。 测量的装置容量范围为2至4吨（7至14千瓦）。测得的空气流量范围为130至510立方英尺/吨（538升/秒/千瓦）。流量不足的原因包括回流管道和格栅尺寸过小、风扇转速设置不当、过滤器和冷却盘管脏污。此外，长时间的迂回运行和挤压或建造的管道也会造成配电系统的高静压。提出了改进现行做法的建议。单位:双关键词:1997年，蒸发器，冷却盘管，性能，测量，单元空调，空调，家用，空气流量，美国，测试，优化，设计，维护，空气过滤器，管道，尺寸，压降，尺寸过小，尺寸过大引用: 研讨会，ASHRAE交易，第103卷，第2部分，波士顿1997年

The performance of conventional split-system residential air conditioners is highly dependent on adequate air flow across the evaporator coil. Sufficient air flow is necessary to achieve a proper balance between sensible and latent cooling capacity. Typical target air flow rates are approximately 350 to 450 cfm per ton (581 to 747 L/s per kW) of cooling capacity. The air flow across the coil in 27 installations in Florida were measured. Both flow hood and strip heat resistance methods were used to measure air flow with an established protocol. The measured installations ranged in capacity from 2 to 4 tons (7 to 14 kW). Measured air flows ranged from 130 to 510 cfm/ton (538 L/s per kW). Reasons for inadequate flows included undersized return ducts and grilles, improper fan speed settings, and fouled filters and cooling coils. In addition, high distribution system static pressures were caused by long, circuitous runs and pinched or constructed ducts. Recommendations are made to improve current practice.Units: DualKEYWORDS: year 1997, Evaporators, cooling coils, performance, measuring, unit air conditioners, air conditioning, domestic, air flow rate, USA, testing, optimising, designing, maintenance, air filters, ducts, size, pressure drop, undersizing, oversizing
