Panasonic C-SDVN453H0D DC Inverter Scroll Compressor – 6.2 HP / 76,000 BTU, R410A, Wide Speed Range

The Panasonic C-SDVN453H0D is a DC inverter scroll compressor operating with R410A refrigerant. At the 60 rps rated point it delivers a cooling capacity of 22,300 W (≈76,100 BTU/h) and COP 3.30. In Panasonic's cross-reference it has the same body as the model coded C-SDP330H02C; it differs in its 6-pole motor and much wider speed range.

15-120 rps Speed Range: The Widest Modulation in Its Class

• 15-120 s⁻¹ (900-7,200 rpm) operating range: It can modulate its capacity at a ratio of 1 to 8. Since it can drop to very low speed at part load, on-off cycling is almost eliminated; the room temperature stays constant and electricity consumption falls.
• 22,300 W cooling / 6,750 W input → COP 3.30 (60 rps, Te 7.2 / Tc 54.4, excluding inverter losses).
• 6-pole DC brushless motor: High torque at low speed — the technical basis of the wide modulation range.
• With oil equalization tube: Equalizes the oil level in multiple (tandem) compressor arrangements.
• Discharge gas temperature limit 115 °C — the compressor protection logic is built around this threshold.

• 🔧 This is an inverter compressor and is not connected directly to the mains. When replacing, also check the driver board; a faulty driver will burn out the new compressor too. Check that the winding resistance is balanced across the three phases (factory value 0.194 Ω @20 °C).
• Watch oil return at very low speed: If it runs continuously below 20 rps, the manufacturer requires it to be raised to the 40-75 rps range for at least 1 minute every hour — this cycle must be defined in the system control software.
• Scroll compressors are sensitive to reverse rotation: Connect the driver output phase sequence according to the manufacturer's diagram.
• R410A is a high-pressure refrigerant: Charge in the liquid phase and pull a deep vacuum; since ester oil absorbs moisture, remove the plugs immediately before installation.
