Heat pump geek chat warning!
Compressors - when do they fail? Why do they fail? What factors play into their failure?
How are manufacturers specifying life of scroll compressors? I've heard some used the number of starts. But as Phil Jennings pointed out to me the other day not all starts are the same. The motor could be cold or ramped up suddenly or warm and ramped up slowly.
Inverter driven heat pumps are supposed to be gentler - does this play out here?
Is running at 100% significantly worse than 80%?
I imagine this isn't a simple thing to quantify but there's plenty of HVAC folk out there who I'm sure know a thing or two about this and I'd love to learn more! (I'm looking at you Graham Hendra Nathan Gambling!)
Happy Modulation Ratio day.
I made that up.
In boiler land, some brands (like Viessmann) are well regarded for having huge modulation ratios, but we don't really talk about this in Heat Pump world, where it's arguably more important!
I was just digging through Ecoforest docs on their R290 heat pump and they claim an 80% modulation ratio, with compressor curves to match! It looks like their compressor's hit top efficiency at 30-40% capacity and they can therefore run them lower before hitting a cycle. Is there a tradeoff of worse performance at the top end?
Question - do any other R290s beat this, or even publish this kind of data?
Let's Name and.... Proclaim the best for modulation ratio.
