1. Product Description & Shared Advantages
Technology:Hermetic reciprocating (piston) compressors.
Refrigerant: Primarily designed for R404A, with compatibility for other common commercial refrigerants like R134a.
Pressure Type:Medium-High Back Pressure compressors, suitable for medium evaporation temperature applications.
Displacement Range: The models are differentiated by their cylinder displacement. The numerical part (e.g., 510, 512, 513, 515) indicates different performance levels, with the AJ5515E being the highest-capacity model in this group.
Design Philosophy:They are designed as reliable, efficient, and cost-effective workhorses for commercial refrigeration equipment.
Shared Advantages
High Reliability: Feature heavy-duty construction with robust housings, high-quality crankshafts, and valve plates, ensuring long-term stable operation in demanding commercial environments.
Excellent Energy Efficiency: Optimized internal flow paths and motor design deliver a competitive Coefficient of Performance (COP), helping to reduce operating costs.
Strong Compatibility: Ability to adapt to multiple common commercial refrigerants, providing flexibility for equipment manufacturers.
Integrated Protection: Built-in motor protectors effectively prevent motor damage caused by overheating, overload, and other abnormal conditions.
2. Model Comparison
| Model | Approx. Cooling Capacity | Approx. Horsepower | Approx. Displacement | Performance Positioning |
| AJ5510F | Medium | Medium (e.g., 3/4 HP) | Medium | The mainstream mid-range model in the series, balancing performance and cost. |
| AJ5512E | Medium-High | Medium-High (e.g., 1 HP) | Medium-High | Enhanced performance model, offering greater cooling capacity than the AJ5510F. |
| AJ5513E | High | High (e.g., 1.5 HP) | High | A high-power model for equipment with greater cooling demands. |
| AJ5515E | Very High | Very High (e.g., 2 HP) | Very High | The top-tier model in this series, providing the maximum cooling capacity. |
Comparison Summary:
1. Performance Gradient: From AJ5510F to AJ5515E, the cooling capacity, horsepower, and displacement typically increase sequentially. This creates a clear performance ladder, allowing equipment manufacturers to select the perfect model based on specific cooling requirements.
2. Electrical Parameters: Rated current, starting current, and other electrical parameters will also vary accordingly and must be verified during design or compressor replacement.
3. Physical Dimensions: While structurally similar, higher-power models may have slight differences in physical dimensions and pipe connections, which should be noted during installation.
3. Application Scenarios
This series is collectively suited for a wide range of commercial medium-temperature refrigeration equipment.
Model-Specific Recommendations:
AJ5510F / AJ5512E:
Typical Applications: Medium-sized vertical/horizontal beverage coolers, convenience store display cases, standard kitchen worktop refrigerators, hotel minibars.
Scenario Characteristics: These are the most widely used models, suitable for most standard-sized commercial refrigeration equipment.
AJ5513E:
Typical Applications: Large ice cream display cases, high-volume deli display cases, comprehensive display cases with high thermal load, small walk-in cold rooms.
Scenario Characteristics: Used in scenarios requiring stronger cooling capacity, larger equipment volume, or frequent door openings.
AJ5515E:
Typical Applications: Large walk-in cold rooms, commercial freezers with critical pull-down requirements, large centralized beverage cooling systems.
Scenario Characteristics: As the most powerful model in the series, it is used for the highest and most demanding cooling requirements.
