Server rooms reject enormous, constant heat. An energy recovery wheel between the exhaust and make-up air streams cuts the cooling load and can redirect that warmth to heat adjacent office space. For data centers chasing PUE, recovery on the ventilation air is a straightforward win. The load you can recover IT power is almost entirely […]
Fume Hood Exhaust Recovery: Wheels vs Plates
Laboratories exhaust enormous volumes of conditioned air through fume hoods, often around the clock. Recovering the energy in that exhaust before it leaves the building is one of the fastest-payback upgrades in laboratory HVAC — and the choice between a rotary wheel and a plate exchanger decides how much you actually save. Why labs bleed […]
有机朗肯循环：从废热到电力
Heat That Usually Goes to Waste Many industrial processes reject heat at temperatures too low for conventional steam turbines but still high enough to be useful. Instead of venting it, that heat can be converted into electricity with an Organic Rankine Cycle. How ORC Works An ORC is a Rankine cycle that uses an organic […]
Waste-Heat Recovery in Food & Agri Drying
The Drying Energy Problem Drying is one of the most energy-intensive steps in food and agriculture processing: grains, herbs, vegetables, and spices all need controlled heat over long periods. Much of that thermal energy leaves the plant as hot, moist exhaust air. Recovering Heat from Exhaust Exhaust from drying tunnels still carries usable sensible heat. […]
Heat Pipe & Run-Around Coil: Separate Air Streams
The Separation Problem Some sites cannot mix supply and exhaust air at all: cleanrooms, hospitals, and hazardous or corrosive environments. Rotary wheels and plate exchangers move energy through a shared surface, so engineers turn to technologies that keep the streams fully isolated. Heat Pipes A heat pipe is a sealed tube filled with a working […]
Heat Recovery in HVAC: Cutting Energy with Air-to-Air
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 […]
数据中心为何押注废热回收
The Data Center Heat Problem Data centers use a large share of the world’s electricity, and almost all of it ends up as heat. Traditionally that heat is dumped outdoors through cooling towers and chillers. With energy costs climbing, operators are asking a simple question: can that heat be used instead of wasted? Two Main […]
Heat Recovery News 2026
Why Heat Recovery Is Moving to the Top of the Agenda For years, capturing waste heat was treated as a bonus project for when the budget allowed. In 2026 that mindset has changed. Energy prices, carbon costs, and tighter efficiency rules have pushed heat recovery from the optional list to the core strategy list for […]
旋转式热回收轮：工作原理与适用场景
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.
