Product Description for Models C-SBX150H38A, C-SBX150H38C, C-SBX160H38A
These three models belong to the Semi-Hermetic Screw Compressor seriesunder the Panasonic Sanyo brand, designed primarily for large-scale commercial and industrial refrigeration applications. They share the same platform but differ in capacity and motor configuration. Below is a comparative product description for the models C-SBX150H38A, C-SBX150H38C, and C-SBX160H38A.
Common Core Features
First, these three compressors share the following key characteristics:
Technology Type:Semi-Hermetic Screw Compressor.
Key Advantages:Smooth operation, low vibration, low noise, long service life, suitable for 24/7 continuous operation.
Capacity Control:Equipped with an infinite capacity control system (slide valve), allowing smooth modulation between 10% and 100% capacity, resulting in high efficiency at part-load conditions.
Typical Applications:Large cold storage warehouses, district cooling, industrial process cooling, large central air conditioning systems.
Power Supply:Typically 3-phase, 380V, 50Hz.
Model Differences: Comparison and Analysis
The numbers and letters in the model codes contain key information. They can be interpreted and compared as follows:
Model
C-SBX150H38A
C-SBX150H38C
C-SBX160H38A
Core Difference Interpretation
Base Model
Same displacement as 150H38A, but different motor pole count or design
Larger rotor diametercompared to the 150 series, resulting in higher displacement and capacity
Rotor Diameter / Displacement
"150" indicates the nominal rotor diameter, medium displacement
Same as H38A, medium displacement
"160" indicates a larger rotor diameter, largest displacement
Cooling Capacity Level
Medium Capacity
Similar capacity level to H38A
Highest Capacity
Motor Code "H38"
Likely indicates the motor frame size or a specific design version
Likely the same motor frame as H38A
Likely indicates a same or similar motor frame as the 150 series
Suffix "A" vs "C"
Standard Version A
Version C, potentially indicating differences in motor poles (e.g., 4-pole/6-pole), efficiency grade, or optimizations for specific refrigerants/conditions
Standard Version A
Inferred Relationship
The base modelfor this displacement
A variantof the A model with the same displacement but potentially different motor performance or applicability
A model with increased displacementfor higher capacity
Summary Explanation:
Displacement Determines Basic Capacity:The increase from 150to 160typically means the core rotor diameter is larger, resulting in greater displacement (volume of gas pumped per revolution) and thus a higher refrigeration capacity under the same operating conditions. The C-SBX160H38A has the highest cooling capacity among these three models.
Suffix Denotes Variants:For models with the same displacement (like the 150 series), the difference between suffixes Aand Cusually lies in specific motor parameters (e.g., different pole counts affecting speed and power), efficiency ratings, or minor tweaks for specific applications (e.g., different refrigerants). The "C" model is a variant of the "A" platform, optimized for different requirements.
