↙️I'm glad that #MIT startup #transaera found a secret sauce for HVAC dehumidification: coupling a new solid desiccant with heat pumps!
↘️I worked on reducing solid and liquid desiccant #HVAC costs back in the 1990s; see "Reduced-Cost, Desiccant-Based DHC Systems"

It turns out that one of the players in my first playtest for the sci-fi HVAC repair TTRPG module I'm working on actually has seven years of professional HVAC experience! What a fantastic coincidence!

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.

#askfedi #indoorenvironment #hvac #dust #allergen #filtration
We’re discovering our passion for open doors and windows is brining in a LOT of dust. We can skate on the tile floors because of it.
Rather than close up and go on AC, I’m thinking of making/buying air filters for the windows. Let’s assume full-width, but only about 6” tall. Just basic furnace filter material, MERV 8 or so.
Is this a workable solution?
But wait, there’s more…

Good morning. 🌺🌻🌼
23 April 2026
We’re getting an early start this morning — the HVAC crew is here cleaning our system. Until yesterday, I didn’t even know AC cleaning was a thing. The tech who came out found what he called “biological growth” inside the blower assembly. I’m assuming that means mildew or mold. Nothing dramatic, of course — no tendrils creeping out of the vents or alien spores waiting to transform us. At worst, there might be tiny particles that irritate allergies. The blower assembly wasn’t in terrible shape, but any buildup can interfere with airflow and make the fan work harder. There’s always something, isn’t there.
Growing up, we never had air conditioning. We had windows and fans, and in some places those big old water coolers that sat in a window and blew damp air into the room. Some folks called them swamp coolers. I can’t help wondering now what kind of mildew those things must have collected. I remember sitting right in front of one on hot days, hoping for relief — it didn’t do much.
I honestly don’t remember the first time I lived in a house with AC. Probably sometime in the 70s. Even after that, I spent a lot of years in places where the heat wasn’t too bad. When we lived in Germany around the turn of the century, we didn’t have AC at all — you just opened a window and that was that.
Before I got used to having air conditioning, the weather was simply something you adapted to. But here in Louisiana, where the heat and humidity can be downright suffocating, AC in the summer isn’t a luxury anymore — it’s essential.

HVAC repair guy came this morning to replace a part ordered a couple weeks ago. He found the old one still working fine from his previous tinkering. We decided against the new part, since I'll be replacing the boiler & hot water heater with a new single flash heater (wall mounted) soon. He put me in touch with their sales guy on the spot. Cost estimate being prepared.

I have an interesting problem. Our apartment lacks adequate ventilation and our co2 levels are always very high. I have a monitors in multiple rooms and at night with the door closed our bedroom is around 1600-2000+ppm. The recommended levels are under 1000ppm. For adults its not great, but my wife and I are expecting our first in March. Prolonged co2 levels above 1500ppm increased risk potential cognitive effects and 2000ppm is very unhealthy for infants. There aren't any laws or regulations around residential indoor air quality, so the apartment complex doesn't have to remedy the situation.

TIL that HVAC systems are vital to keep people alive in these extreme temperatures
This is a normal temperature in Canada in the state of MontrealSince I live in the tropics I only have to check my PPE for temperatures at the high 40° Celsius and the low 18° c
