III. Detailed Analysis

Group A: HSM150V4UDZ / HSM165V4UDZ — 1.5HP Class Compact & Efficient Choice

• Feature: Both compressors adopt GMCC's mature SM-platform fixed-speed rotary structure. The rotary vanes are precision-machined with an optimized internal structure. They feature high-current-capacity integrated terminal design and laser-welded housing technology, ensuring reliability and safety. Pre-filled with SUNISO 4GSD / NM56EP mineral oil at the factory. The HSM150V4UDZ operating current is 4.85 A, locked rotor current is 26 A, and max operating current is 6.66 A. The HSM165V4UDZ operating current is approx. 5.2 A, max operating current approx. 7.0 A. Both models have a net weight of only 12.3–12.5 kg and an overall height of 292–300 mm.
• Advantage: This group's core strengths are compact lightweight design and high energy efficiency. The HSM165V4UDZ achieves a COP of 3.12, while the HSM150V4UDZ has a COP of 2.96, leading the industry among comparable fixed-speed R22 compressors. The proven SM platform has passed rigorous durability tests and engineering validation, maintaining excellent reliability even under high-frequency operation. The lightweight design reduces logistics costs and installation difficulty.
• Benefit: For OEM air conditioner manufacturers, the compact size frees up more space in outdoor unit layouts, while the lightweight design cuts shipping costs. For the aftermarket/service sector, standardized connections and a proven platform provide a plug-and-play replacement solution. For end users, the high efficiency of the R22 system and the long service life of the rotary compressor reduce long-term operating costs while ensuring excellent cooling performance.

Group B: HSM200V4UDZ / HSM215V4UDZ — 2–2.5HP High-Capacity & Ultra-Quiet Choice

• Feature: The HSM200V4UDZ employs a high-performance pump body and a high power-density motor. By optimizing the rotary vane profile and internal flow channels, it achieves an outstanding energy efficiency with a COP of up to 4.35 W/W, while noise is controlled below 50 dB, reaching industry-leading quiet levels. The HSM215V4UDZ delivers 3,700 W of cooling output with its 21.4 cm³ large displacement, a COP of 3.05, and also features sub-50 dB low-noise operation. Both compressors are equipped with intelligent control functions for low-noise, low-torque-ripple operation.
• Advantage: This group's core strengths are ultra-high energy efficiency and ultra-low noise. The HSM200V4UDZ's COP of 4.35 W/W is the highest in the HSM series, far exceeding comparable fixed-speed R22 compressors. Sub-50 dB noise control makes it especially suitable for environments with strict acoustic requirements. The compact 12.7 kg net weight and 292–300 mm height allow for flexible system integration. The HSM200V4UDZ also offers a miniaturization advantage, making it ideal for space-constrained cooling systems.
• Benefit: For commercial A/C manufacturers, the HSM200V4UDZ's COP of 4.35 means every 1 kW of electricity consumed produces 4.35 kW of cooling, significantly reducing end-user electricity bills. For medical equipment and precision instrument cooling, the sub-50 dB ultra-low noise and intelligent control functions ensure a quiet and stable operating environment. For projects requiring higher cooling capacity, the HSM215V4UDZ's 21.4 cm³ displacement and 3,700 W output provide ample cooling reserves.
