This series is positioned as the energy efficiency benchmark within the R22 refrigerant framework. The "X" in the model designation stands for the high-performance version, representing the brand's specialized upgrade solution for R22 systems pursuing ultimate energy efficiency. Unlike the "Reliability First" approach of the C-SC series and the "Compatibility First" approach of the C-SCN series, the underlying design logic of the C-SCX series is "Efficiency First" — achieving a significant breakthrough in energy efficiency through precise optimization of the scroll profile under the same displacement and operating conditions.
Energy Efficiency Leap: Taking the C-SCX435H38B as an example, it delivers a cooling capacity of 36.1 kW at 50Hz with a COP of up to 3.47 W/W. Compared to the C-SC series of the same displacement class (COP approx. 3.29~3.38), the energy efficiency is improved by about 3%~5% — a gap that translates to considerable electricity cost savings annually in large commercial systems. With a displacement of 195 cm³/rev, it stands as a large-displacement, high-efficiency model within the brand's R22 refrigerant series.
Scroll Profile Optimization: The core source of this efficiency improvement is not a simple material upgrade, but the geometric optimization of the scroll plate profile. Through computer-aided design, the involute starting angle, wall thickness distribution, and discharge angle of the scroll plates are precisely calibrated to reduce refrigerant leakage within the compression chamber and over-compression losses, optimizing the volumetric efficiency per revolution. This is the most fundamental technical difference from the C-SC base series.
Medium-to-High Temperature Fresh-keeping Specific: This series is explicitly optimized for Medium-to-High Temperature (High Back Pressure) application scenarios, and is particularly suitable for air conditioning, constant temperature control, and medium-to-high temperature fresh-keeping fields where the evaporation temperature is above 0°C. Within this temperature range, its energy efficiency advantages can be fully realized.
Commitment to R22 Refrigerant: Unlike the R410A route of the C-SCP series, the C-SCX series remains committed to R22 refrigerant. It provides a pragmatic choice for users who, due to equipment compatibility or retrofit cost reasons, cannot yet switch to environmentally friendly refrigerants, allowing them to maximize energy efficiency within the existing refrigerant framework.
Typical Applications: Air-cooled units, commercial air conditioning, precision air conditioning, industrial refrigeration, medium-to-high temperature fresh-keeping, and other R22 system scenarios with high energy efficiency requirements.
