Frequently asked questions
What refrigerants does the Copeland YB31K1E-TFD support?
The Copeland YB31K1E-TFD is qualified for R1234yf, R134a, R404A, R407A, R407C, R407F, R448A, R449A, R450A, R454A, R454C, R455A, R513A. The table above lists capacity at ultra-low, low, medium and high temperature duty for each refrigerant, with the evaporating and condensing temperature each value was calculated at. Those conditions differ by refrigerant, so read them per row.
What is the cooling capacity of the Copeland YB31K1E-TFD?
Running on R454A, the Copeland YB31K1E-TFD delivers 8.87 kW at MT (-10 / 45 °C), 10.66 kW at HT (-5 / 45 °C). These are calculated cooling capacities at the rating basis the manufacturer declares with its data, not measured values. Use the Benchmark tool to evaluate capacity at your exact SST/SDT and superheat conditions.
What type of compressor is the Copeland YB31K1E-TFD?
DigiEntropy classifies the Copeland YB31K1E-TFD as YB*K1 Quest. Browse the Copeland catalog to compare nearby models from the same brand.
Can the Copeland YB31K1E-TFD be retrofit to a lower-GWP refrigerant under EU F-Gas Regulation 2024/573?
Open the F-Gas Retrofit tool with this model pre-selected to see drop-in alternatives ranked by capacity match, COP, GWP, PFAS impact, and 2026/2030/2035 phase-out timeline.
Where does the Copeland YB31K1E-TFD performance data come from?
From Copeland's own published performance data, evaluated at the suction and liquid conditions the manufacturer declares with it. Which rating standard the manufacturer certifies to (EN 12900 or AHRI 540) is not stated on this page; check the manufacturer's datasheet. Fit your own data in the Polynomial Fitter tool.
