III. Detailed Overview
Feature: The C-SBR series adopts a fully hermetic scroll structure, factory-charged with mineral oil for perfect compatibility with R22 refrigerant. A high/low-pressure partition design reduces fixed-scroll strain and forms an internal discharge muffler. A tip seal ring seals the disengagement gap between the orbiting and fixed scrolls caused by axial force, improving energy efficiency. The compressor's main and auxiliary bearings utilize high-performance rolling bearings; an internal protector ensures reliable motor protection upon direct power cutoff. A suction strainer is installed at the suction port for enhanced compressor protection.
Advantage: This series centers on native R22 system compatibility and high energy efficiency. The C-SBR195H38A achieves a COP of 3.20 at 50Hz and 3.23 at 60Hz. The C-SBR235H38A delivers a cooling capacity of 19,200W at 50Hz with a COP of 3.20, and a COP of 3.27 at 60Hz. The cooling capacity range of 16 kW to 23.2 kW precisely matches the requirements of 5.5–7 HP commercial air conditioning systems.
Benefit: For industrial air conditioning and heat pump system manufacturers, the C-SBR series precisely matches the needs of 5.5 HP-class systems with 16 kW (50Hz) / 19.4 kW (60Hz) cooling capacity. For the maintenance and replacement market of existing R22 systems, this series represents a plug-and-play replacement solution—requiring no additional refrigerant oil changes or system piping modifications. For end users, the high efficiency of R22 systems combined with the long-service-life design of scroll compressors significantly reduces total lifecycle operating costs while ensuring reliable cooling performance.
IV. Application Scenario Quick-Selection Guide
