Panasonic C-SDP205H02B DC Inverter Scroll Compressor – 4 HP / 46,100 BTU, R410A, 380V Three-Phase

The Panasonic C-SDP205H02B is a DC inverter scroll compressor operating with R410A refrigerant. At standard air conditioning conditions (Te 7.2 °C / Tc 54.4 °C) it delivers a cooling capacity of 13,497 W (≈46,100 BTU/h); it is in the 4 HP class. It is used in air handling units, packaged air conditioners, heat pumps and inverter-controlled commercial refrigeration units.

DC Inverter Scroll: Continuously Adjusts Capacity to the Load

• DC inverter-driven: The compressor is not supplied directly from the mains but with variable frequency and variable voltage from the unit's driver (motor voltage 231 V class). At part load the speed drops; by running continuously instead of cycling on and off, it keeps the temperature constant and eliminates the starting current load.
• 13,497 W cooling / 4,151 W input → COP 3.25 (Te 7.2 / Tc 54.4, SH 11.1 K, SC 8.3 K, 60 Hz reference).
• Variable-speed envelope: Evaporating -15…+12 °C; the condensing limit depends on speed — up to 65 °C at low speed (30-44 rps), 45 °C at full speed (75-90 rps). In hot climates it protects capacity by reducing speed.
• Quiet: Max. 61 dB — among the quietest in this capacity class.
• Compact: 36 kg body with 42.3 cm³/rev displacement; fits into narrow outdoor unit chassis.

• 🔧 This is an inverter compressor and is not connected directly to the mains. When replacing, also check that the driver (inverter) board is sound; a faulty driver will burn out the new compressor too. Check that the winding resistance is balanced across the three phases.
• Scroll compressors are sensitive to reverse rotation: Connect the driver output phase sequence according to the manufacturer's diagram; in reverse rotation no pressure builds up and noise increases.
• R410A is a high-pressure refrigerant: Make sure the lines and fittings are rated for R410A pressure; always charge in the liquid phase.
• Ester oil absorbs moisture: Remove the plugs immediately before installation and dry the system with a deep vacuum (≤500 micron); when replacing, measure the remaining oil and top up to 1.7 L.
