Step 1 – Known airflow Start with the supply/exhaust airflow Q (m3/h). For balanced AHUs, Q_supply approx Q_exhaust. Step 2 – Temperature difference Find the outdoor design temperature T_out and the exhaust (room return) temperature T_exp. The available temperature lift is DeltaT = T_exp – T_out. Step 3 – Effectiveness Choose an effectiveness epsilon (typical […]
空气处理机组 (AHU) 与热回收集成
An air handling unit (AHU) conditions outdoor air before it enters a building. Without recovery, that outdoor air must be heated or cooled from scratch every hour. Adding a heat recovery core to the AHU is the single highest-impact energy measure for ventilation systems. Where the Exchanger Sits in an AHU The recovery core is […]
将空气-空气热回收集成到空气处理机组（AHU）中
An air handling unit is where air-to-air heat recovery earns its keep in commercial buildings: the AHU already moves the supply and return air, so dropping a recovery core into the airstream is the lowest-cost way to reclaim energy at scale. But integration is not simply placing a wheel into the casing, where the core […]
Pharma & Hospital Heat Recovery: Zero Cross-Leak
How to specify heat recovery for pharmaceutical cleanrooms and hospital isolation rooms where cross-contamination is unacceptable. Plate, heat pipe, and run-around coil compared.
显热回收 vs 全热回收：如何选对换热器
A practical guide to choosing between sensible-only and total-energy recovery for commercial AHUs, with capital cost ranges and break-even analysis.
板式 vs 热管 vs 旋转式：该指定哪一种
A practical selection framework comparing plate, heat pipe, and rotary enthalpy exchangers across efficiency, cross-contamination, pressure drop, and lifecycle cost for industrial ventilation projects.
AHU组件：风机、过滤器与回热芯体
Anatomy of an Air Handling Unit An AHU conditions outdoor air before it enters a building. The core components are: the supply fan, the exhaust fan, filters, coils (heating/cooling), and – increasingly – a heat recovery core. How these are arranged decides both air quality and energy use. Fans Supply and exhaust fans move the […]
