Pool Dehumidification & Heat Recovery

A 室内泳池（natatorium）是任何建筑中最严酷的HVAC环境之一：温水持续蒸发，使空气携带蒸汽并在每个冷表面凝结，若被忽视便会腐蚀结构。通风必须去除湿气，而不仅仅是热量，而它抽入的新风调节成本昂贵。恰当的气－气回收策略应同时回收排风的显热与潜热，并预热进入的空气。本文涵盖泳池为何是能耗噩梦、回收架构、材料选择与选型。

Why pools are an energy nightmare

开敞水面的蒸发毫不留情；一座25米泳池一天可蒸发数百升水，而这些蒸汽携带着大量潜热。建筑必须通风足够强劲，使室内湿度保持在约60%RH以下，以免冷凝侵蚀窗户、钢材和配件。但排出这股湿空气，等于丢弃了它的两种能量——热量与湿气，而新风在进入前必须被加热（冬季往往还需间接除湿）。 空气－空气回收 拦截排风，回收其中大部分流失的能量。

Recovery architecture

The standard approach places a plate or wrap-around coil ahead of a heat-pump dehumidifier. The recovery device pre-warms the make-up air with the exhaust and, in an enthalpy design, also transfers moisture, reducing the dehumidifier’s load. A wrap-around (run-around) coil loop is attractive in pools because the supply and exhaust are fully isolated — useful where the exhaust is chlorine-laden and you do not want any path back to supply. Pair the recovery with a dedicated pool dehumidifier so the system controls humidity first and recovers energy second.

Material choices

氯及关联化学品具有腐蚀性，因此材料选择决定了使用寿命。气流中的裸钢是个错误；PVC、钛或涂层铝芯体对环境耐受性好得多。芯体必须可排水，以免冷凝水滞留滋生生物膜，且换热器必须便于定期冲洗。我们的 选型指南 对比铝、不锈钢与PVC在空气化学环境下的选项。

Sizing rules

根据泳池在设计温度与游泳负荷下的蒸发率确定排风与新风的路径，再依据 resultant 风量和冬季温差为回收芯体选型。目标板式显热60%–70%，剩余潜热负荷由除湿机承担。切记双重收益：居住者舒适与结构保护。选型过小会让冷凝失控；过大则增加压力损失与风机成本。均衡的设计通常通过降低泳池采暖负荷与新风空调负荷，在二至四年内回本。

常见问题

Why are pools an energy nightmare?

Open water evaporates continuously, loading the air with vapour that condenses on cold surfaces and attacks the structure. Ventilating that moisture away throws away both sensible and latent energy, and the make-up air is expensive to condition.

What recovery architecture works?

A plate or wrap-around coil ahead of a heat-pump dehumidifier pre-warms make-up air with the exhaust, and an enthalpy design also transfers moisture, reducing the dehumidifier load. A wrap-around coil fully isolates the chlorine-laden exhaust.

Which materials resist the pool environment?

Corrosion-resistant cores such as polymer, epoxy-coated aluminium or stainless paths are specified because the warm, chlorinated, high-humidity airstream quickly attacks bare metals.

How is the recovered energy used?

Recovered energy pre-heats and partially dehumidifies incoming air, cutting the heating and dehumidification duty and protecting the building fabric from condensation.
