R410A compressor — 26.3 kW cooling, 8.82 kW input, COP 2.99 at the AHRI 7.2/54.4 °C rating point.
R410A compressor — 30.8 kW cooling, 10.95 kW input, COP 2.82 at the AHRI 7.2/54.4 °C rating point.
| Heat-pump frost/defrost derate | 43, from five makers | RMS 0.023, where the makers stand 0.029 from each other at the forty temperatures they share — the one generic curve is closer to each of them than they are to one another, and none is served much worse than any other (0.019–0.028 apiece). The EnergyPlus model this replaced had the shape inverted (deepest just below its 5 °C cutoff, then a 29-point step across it) and read up to 0.15 low |
| A maker's inverter rotary read off its scanned specification book: the Mitsubishi Electric LNB53FCAMC | 702 digitised points (26 evaporating temperatures × 3 condensing × 3 quantities × 3 speeds), each curve read at about half a pixel; the rating point; the speed curve at 30–90 rps; a grid over the envelope | the fitted sets land on every digitised point — capacity and flow within 1.4 %, input within 0.5 % — and the 60 rps step reads the rating point within the sheet's own ±5 %. The book's two charts agree on capacity and disagree on input by up to 8 % at the lower speeds, which the sheet itself allows ('performance is varied by driver characteristics'); between the printed speeds the three-step interpolation stays within four points of that disagreement. Capacity over flow sits a constant 2.5–3.7 % above the cycle's refrigerating effect, identical at every speed to 0.2 points — a basis the drawing carries and the sheet does not state, not a reading error — and the flow implies 0.76–0.96 volumetric efficiency on 53.7 cm³. Recorded, not corrected: the maker puts the same capacity at 27.8 K return-gas superheat as at 11 K, where AHRI 540's density correction would add several per cent |
