Commercial Kitchen Heat Recovery: Capturing Energy from Exhaust with Air-to-Air Heat Exchangers Walk into any busy restaurant kitchen at dinner service and you will feel it: a wall of hot, greasy exhaust air being thrown out through the hood, while at the same time the make-up air unit is burning energy to condition cold outside […]
Heat Recovery in HVAC Systems: Cutting Building Energy Use with Air-to-Air Exchangers
Why Ventilation Wastes Energy Buildings need fresh air, but exhausting conditioned indoor air and bringing in untreated outdoor air can waste a large share of heating and cooling energy. In cold weather the incoming air must be heated; in hot weather it must be cooled. Air-to-air heat recovery closes that gap. How Air-to-Air Recovery Works […]
Rotary Heat Recovery Wheels: How They Work and Where to Use Them
Rotary heat recovery wheels: how the rotating matrix recovers 70-90 percent of exhaust energy, where to use them, sizing, maintenance and comparison with plate and heat-pipe recovery.
Heat Exchanger Selection Guide: Differences and Applications of Plate, Shell-and-Tube, and Rotary Exchangers
换热器是热回收与工艺换热的核心设备。本文对比板式、管壳式、转轮式、气气及微通道换热器的原理、优缺点与适用工况，并给出选型步骤与维护要点，助您精准匹配工况、提升换热效率。
What Is a Good Flow Velocity for an Air-to-Air Heat Exchanger?
The flow velocity selection for an air-to-air heat exchanger depends on the operating conditions, exchanger type, design objectives, and fluid properties. The following are recommendations and typical ranges: Typical flow velocity range Gas velocity: 10–30 m/s. Low velocity (~10 m/s): for pressure-drop-sensitive or energy-saving scenarios. High velocity (~20–30 m/s): for enhanced heat transfer; watch pressure […]
