商业建筑热回收：办公楼、酒店、混合用途

The everyday opportunity

O写字楼、酒店与混合用途建筑以高新风率全天候运行通风。回收这部分排风能量，是多数商业地产最大的 HVAC 节能点。

Technology mix

• 写字楼 – balanced AHUs favor 板式 or 转轮式 热回收；详见 AHU 回收.
• 酒店 – guest-room ventilation plus laundry and pool loads; pair with 零售 与 休闲 回收思路。
• 混合用途 – a central plant with 区域式共享 更胜一筹。

Climate matters

采用 基于气候的选型：潮湿区域用全热芯体，干燥区域用显热板式。注意 转轮维护 若选择转轮式，请务必留意。

投资回收

多数商业改造可在 3–5 年内回本。请用我们的 回收期方法 并借助以下验证 效率指标.

Where the savings come from

• Make-up air pre-conditioning – the largest load in continuously ventilated buildings.
• Reduced boiler and chiller runtime, especially during shoulder seasons.
• Smaller HVAC plant if recovery is specified early in design.

Specification tips

Favor sensible plate cores in dry climates and enthalpy wheels where humidity control dominates. Size the core from measured airflow, not nameplate, and keep a maintenance window for filter and wheel service.

常见问题

What payback can commercial buildings expect?
Most retrofits pay back in 3-5 years through lower heating, cooling and fan energy.

Plate or rotary for an office AHU?
Balanced offices usually suit plate or rotary; choose rotary when humidity recovery matters, plate when contamination control is tighter.

Do hotels need special handling?
Guest rooms, laundry and pools add latent loads, so enthalpy recovery often pays; pair it with the building central plant.
