III. Detailed Overview

Feature: The C-SC series adopts a fully hermetic scroll structure, optimized for high-power R22 applications. High-performance rolling bearings are used for main and auxiliary shafts; an internal protector ensures reliable motor protection upon direct power cutoff; a suction strainer at the suction port provides enhanced compressor protection. The scroll wraps feature an asymmetric profile design that optimizes refrigerant flow channels, reduces gas leakage, and improves compression efficiency. A built-in discharge temperature protection device ensures safe operation under high-temperature conditions.

Advantage: This series centers on high energy efficiency and low-noise operation. The C-SC753H8H delivers 30,600W cooling at 50Hz with a COP of 3.38, and 36,900W at 60Hz with a COP of 3.32. The C-SC903H8H provides 36,100W at 50Hz with a COP of 3.31. The scroll compression process is smooth, with minimal pressure differential between adjacent compression chambers, minimizing leakage and resulting in significantly lower noise than traditional reciprocating compressors. The 10–12 HP complete power coverage meets diverse demands from large commercial air conditioning to industrial refrigeration systems.

Benefit: For large commercial air conditioning and water chiller applications, the C-SC series delivers 30.6 kW to 36.9 kW of cooling with COPs of 3.31–3.38, significantly reducing operating electricity costs while ensuring cooling performance. For industrial refrigeration systems, the high efficiency of R22 and the long-service-life design of scroll compressors ensure economy and reliability during prolonged continuous operation. For equipment manufacturers, the three capacity tiers from C-SC753 to C-SC903 cover the mainstream cooling capacity segments of large commercial air conditioners, reducing model variety and simplifying product line management.

IV. Application Scenario Quick-Selection Guide

Application Scenario	Recommended Model	HP	Key Advantage
Large Commercial A/C	C-SC753H8H/K	10.0	30.6kW, COP 3.38
Industrial Refrigeration	C-SC863H8H	11.0	High cooling capacity
Large Water Chiller	C-SC903H8H/K	12.0	36.1kW, COP 3.31

Selection Tip: For 10 HP, choose C-SC753H8H/K; for 11 HP, choose C-SC863H8H; for 12 HP, choose C-SC903H8H/K.

V. Frequently Asked Questions

Q1: What are the cooling capacity and COP of C-SC753H8H?

The C-SC753H8H is a 10 HP scroll compressor with a displacement of 171.2 cm³, using R22 refrigerant. At 50Hz, cooling capacity is 30,600W with a COP of 3.38; at 60Hz, cooling capacity is 36,900W with a COP of 3.32.

Q2: What is the difference between the H and K suffixes?

The H/K suffix difference mainly lies in piping interface specifications and electrical connection configurations; core performance parameters are identical.

Compressor Specification Recommendation

Panasonic/Songyang C-SC Series (10–12 HP, R22)

When specifying compressors for large-tonnage commercial and industrial applications, the conversation inevitably narrows to three variables: electricity cost, acoustic performance, and mean time between failures. The C-SC series addresses all three with measurable outcomes.

At 30.6 kW to 36.9 kW cooling output and COP ratings reaching 3.38, the C-SC753H8H alone can reduce annual electricity consumption by thousands of kilowatt-hours compared to legacy reciprocating units of equivalent tonnage. The asymmetric scroll wrap geometry—a design choice that minimizes inter-chamber pressure differential—doesn't just improve thermodynamic efficiency; it fundamentally changes the acoustic signature of the compressor, bringing noise levels well below those of conventional piston-driven alternatives. This matters in commercial environments where HVAC noise directly impacts occupant comfort and regulatory compliance.

For operations requiring continuous-duty reliability, the C-SC platform integrates three layers of protection: a built-in discharge temperature sensor for high-ambient safety, a suction strainer blocking particulate ingress, and an internal motor protector that trips on thermal overload. These are not optional add-ons—they are engineered into every unit at the factory.

The business case is straightforward. Fewer model variations (three capacity grades covering 10–12 HP) mean simplified spare parts inventory for service teams and reduced SKU complexity for OEMs managing product lines across multiple tonnage classes. For facilities still operating R22-based infrastructure, the C-SC series represents a direct, performance-upgraded replacement path without the capital expenditure of a full system conversion.

Engineered for large-scale applications, the Panasonic/Songyang C-SC Series combines 10–12 HP output with a COP of up to 3.38, providing reliable power for commercial and industrial cooling.
