Fans Don’t Cool Rooms and 3 Other Myths About Home Energy Conservation
Shutterstock Want to spend less on energy? You’re not alone. Summer’s approach means air conditioning season is almost here, just in time for a global energy crisis. Naturally, we’re all looking for ways to lower our energy bills. There’s a lot of great advice out there, from ditching incandescent lights to getting a heat pump. But there’s also some energy-saving advice that is useless—and a few tips that actually waste energy.......Continue reading.. By: Justin […] -

Tip: you can reduce the heat your laptop/desktop computer generates by limiting its CPU frequency.
To restrict all cores to 800MHz on Linux, run one of these two commands as root:
cpupower frequency-set -u 800MHz
echo 800000 >/sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq

Heat Recovery Ventilator (HRV) — Operating Principle
A recuperator (heat recovery unit) transfers heat from exhaust air to incoming fresh air without mixing the two streams.
---
How It Works
Two airflows:
Exhaust air (warm, from indoors)
Supply air (cold, from outside)
They pass through a heat exchanger:
separated by plates or channels
no direct mixing
heat transfers through the material (conduction)
Result: → supply air is preheated
→ exhaust air is cooled
→ overall heat loss is reduced---
Types of Recuperators
1. Plate Heat Exchanger
aluminum or plastic plates
efficiency: ~60–90%
no moving parts
2. Rotary (Wheel) Heat Exchanger
rotating drum
transfers heat and some moisture
efficiency: up to ~85–90%
3. Counterflow Heat Exchanger
air streams move in opposite directions
highest efficiency: up to ~95%
---
What Is Transferred
heat (primary)
sometimes moisture (in enthalpy units)
---
Efficiency Example
outside: 0°C
indoor: +22°C
after recovery: ~16–20°C
---
Advantages
reduced heating energy demand
continuous ventilation without major heat loss
improved indoor air quality
---
Limitations
frost formation in winter (needs bypass or preheater)
filter maintenance required
upfront cost
---
Core Idea
A recuperator doesn’t generate heat — it recovers and reuses it.
