HyperHeat vs. Non-HyperHeat Minisplits

yesimon | Posted in Energy Efficiency and Durability on

For some reason LGRED mini split condensers have worse efficiency/COP/SEER/HSPF across the board (various btu output at various temperatures) than non-HyperHeat units, except for the edge case of capacity maintenance at 5F. Expected annual operating cost ~10% greater.

For example compare LMU240HV (24k btu, non-hyperheat)

With LMU240HHV (24k btu, hyperheat)
https://ashp.neep.org/#!/product/25831

The LGRED condenser weighs 50 lbs more (more machinery, bigger heat exchanger?) but strangely performs worse. Is this a model year/design refresh issue? Mitsubishi units are about the same efficiency between Hyper and non-HyperHeat.
