Panasonic 5KS196DBA21 Rotary Compressor – 1.3 HP / 16,000 BTU, R410A, Single-Phase

Panasonic 5KS196DBA21 is a single-phase rotary compressor operating with R410A refrigerant. With a displacement of 19.6 cm³/rev, it delivers a cooling capacity of 4,740 W (≈16,173 BTU/h); with COP 3.01, it is one of the efficient models in its class. It is used in split air conditioner outdoor units, small commercial air conditioners and dehumidifiers.

16,000 BTU Class: The Standard Compressor of Split Air Conditioner Outdoor Units

• 4,740 W cooling / 1,575 W input → COP 3.01 (N-TEC condition: Te 7.2 / Tc 54.4 °C).
• Single-phase supply: 220-240 V ~ 50 Hz — no three-phase required; runs directly in residential and small commercial applications.
• Run capacitor 45 µF / 370 V — keep the capacitor value when replacing; a wrong value strains the compressor.
• Rotary quietness: Less vibration than reciprocating equivalents; the accumulator provides protection against liquid slugging.
• R410A compatible: The standard refrigerant of current split air conditioners; runs on ester oil.

Technical Specifications and Installation Notes

• Model: Panasonic 5KS196DBA21  |  Supply Code: 10.183.0077
• Type: Hermetic rotary (single piston)  |  Refrigerant: R410A
• Power Class: 1.3 HP  |  Capacity: 4,740 W / ≈16,173 BTU/h
• Power Input: 1,575 W  |  COP: 3.01  |  Displacement: 19.6 cm³/rev
• Power Supply: 220-240 V ~ 50 Hz, single-phase  |  Run Capacitor: 45 µF / 370 V
• Operating Range: HBP (+7.2 °C / +54.4 °C) — air conditioning application

• 🔧 Keep the capacitor value exactly the same. If a value other than 45 µF/370 V is fitted, the compressor struggles at start-up and the winding heats up. It is best to renew the capacitor as well when replacing.
• R410A is a high-pressure refrigerant: Make sure the lines and fittings are rated for R410A pressure; charge in the liquid phase.
• Ester oil absorbs moisture: Open the plugs just before installation and dry the system with a deep vacuum (≤500 micron).
• Upright mounting is required: Rotary compressors must not be run tilted; fix it upright with vibration mounts.
• Do not remove the accumulator — it is the only component that protects the compressor against liquid return.
