Personal experiences with Daikin Quaternity ductless heat pumps
I've read many times about the independent humidity control of Daikin's Quaternity models. I've even found myself jealous of them after installing a Mitsubishi and feeling muggy in my house on a mild spring day when there is little need for cooling, and the dry mode makes us feel too cold. There are illustrations and videos on the web showing how it works -- the indoor coil is split into two parts, one of which can be hot and one of which can be cold (at the same time), which allows for dehumidification without cooling. That's great, but in all my perusal I don't recall ever reading a single personal experience with how well this actually works in real life. Does it really maintain a stable humidity level year-round? How much is energy use increased by this additional dehumidification function? And why are these not hugely popular considering all the talk I've seen about latent loads being such an important issue in high performance homes?
