CAJ4511Y and TAJ4511Y are specialized models for low-temperature refrigeration of Tecumseh compressors, mainly used for equipment such as refrigerators and cold storage Basic Parameters
Product Description for Refrigeration Compressors CAJ 4511Y and TAJ 4511Y These models belong to Panasonic's high-efficiency commercial compressor series. However, unlike the screw compressors discussed previously, they are piston compressors.
Working Principle:Compresses refrigerant vapor through the reciprocating motion of a piston within a cylinder. This is a classic and widely used compression technology known for its maturity, reliability, and cost-effectiveness.
2. Key Features & Advantages
High Energy Efficiency:This series of compressors is optimised to deliver excellent energy efficiency, helping to reduce equipment operating costs.
Robust and Durable:Manufactured using high-strength materials (e.g., cast iron crankcase), they feature a sturdy construction capable of withstanding demanding operating conditions, ensuring a long service life.
Wide Applicability:Designed for applications requiring medium evaporation temperatures and medium cooling capacity, making them an ideal choice for many commercial refrigeration systems.
Low Vibration and Noise:Despite the piston design, relatively smooth and quiet operation is achieved through precise dynamic balancing and internal anti-vibration measures.
Reliable Motor Protection:Built-in motor protection devices effectively prevent motor damage caused by factors like voltage fluctuations or overheating.
Compatibility with Various Refrigerants:Typically designed for use with common commercial refrigerants such as R404A, R507, and R22.
3. Typical Applications
Commercial refrigerated and display cases
Small to medium-sized cold storage rooms
Ice makers
Refrigeration/freezing equipment for the food service industry
Model Difference Comparison: CAJ 4511Y vs. TAJ 4511Y
The letters "C" and "T" in the model code are key to distinguishing these two compressors.
Feature
CAJ 4511Y
TAJ 4511Y
Power Supply Type
Standard Voltage/Frequency Version
Specific Voltage/Frequency Version
Key Difference Interpretation
The letter "C" typically indicates the compressor is designed for standard power systems, compatible with both 50Hz or 60Hz(e.g., 220-240V / 50Hz or 208-230V / 60Hz), offering broader applicability.
The letter "T" typically indicates a specific version optimised specifically for 60Hzpower systems (e.g., 208-230V / 60Hz). Its motor design is precisely matched for that specific frequency and voltage.
Performance
Optimal performance is achieved under the designed standard voltage/frequency.
Delivers its rated optimal performance and efficiency when used with the specific 60Hz power supply it was designed for.
Interchangeability
Can potentially be interchanged with the T-model of the same series if power conditions match, but one must strictly consult the manufacturer's technical manual to ensure parameters like voltage and frequency are fully compatible.
Should not be used under non-specified power conditions (e.g., a 50Hz system), as this could lead to performance issues, overheating, or damage.
Summary Explanation:
The CAJ 4511Yand TAJ 4511Yare semi-hermetic piston compressors from the same platform, sharing the same bore, stroke, displacement, similar mechanical structure, and cooling capacity.
Their core difference lies in the configuration of the motor windings, tailored for different electrical specifications. The "C" version offers greater versatility, while the "T" version is tailored for specific markets(such as North America, which uses 60Hz power).
When selecting, it is essential to choose the correct model based on the standard grid parameters (voltage and frequency) of the equipment's installation location to ensure the compressor operates safely, efficiently, and durably.
