Technical specifications and performance characteristics
Structure type: Both are spiral structures with high and low voltage protection, pressure relief valves, motor overload protection and other devices.
Design lifespan: The design lifespan is 15 years, easy to maintain, and has a long service life.
Noise control: The internal structure is simple, the volume is small, and the weight is light, greatly reducing noise problems.
Efficiency: High efficiency within an appropriate range of cooling capacity, smooth operation, and low vibration
Application scope:
Low temperature freezing and refrigeration systems, such as cold storage, display cabinets, central air conditioning, refrigeration units and other refrigeration equipment.
The Copeland ZB88KQ is a high-efficiency scroll compressor from the ZB Series. Designed for medium-temperature commercial refrigeration applications, it is a popular choice for standard condensing units. It offers a balance of performance and reliability, making it an ideal power source for medium-sized commercial refrigeration equipment.
2. Key Technical Parameters (Typical values, consult official manual for specifics)
Model:ZB88KQ-TFD-XXX (e.g., ZB88KQ-TFD-130)
Refrigerant:Originally designed for R404A, with wide compatibility for environmentally friendly refrigerants like R448Aand R449A.
Displacement:Approximately 23.2 m³/h (This is lower than the ZB95KQ, resulting in a relatively lower cooling capacity).
Power Supply:Three-phase, common specification 380-415V/50Hz.
Application Range:Primarily for evaporating temperatures between -10°C and +10°C.
3. Core Features & Advantages
Proven Scroll Technology:
Excellent Energy Efficiency:Features Copeland's classic scroll design, delivering high efficiency at both part and full load, which helps reduce operating costs.
Robust and Reliable:Compact structure with fewer moving parts ensures smooth operation, minimal wear, and a long service life.
Low Noise and Vibration:Operates much more quietly and with significantly less vibration than piston compressors, improving the user experience.
Comprehensive Motor Protection:
Integrated motor protection module effectively prevents motor burn-out caused by voltage fluctuations, phase loss, or overheating.
Broad Operating Range:
Capable of adapting to various environmental conditions, ensuring stable cooling performance in diverse application scenarios.
4. Typical Applications
The ZB88KQ is commonly found in refrigeration systems for equipment such as:
Commercial Display Cases:Reach-in beverage coolers, ice cream freezers, and deli cases in convenience stores and supermarkets.
Small Walk-in Coolers:Used for cold storage of fruits, vegetables, and dairy products (typically 0°C to +10°C).
Modular Condensing Units:Serves as the core component in standard condensing units produced by many OEM manufacturers.
5. Main Differences from the ZB95KQ
Displacement and Cooling Capacity:The ZB 88KQ has a smaller displacement (~23.2 m³/h) than the ZB 95KQ (~25.1 m³/h), resulting in a lower cooling capacity. Selection should be based on the required cooling load; the ZB88KQ is suitable for systems with slightly lower capacity demands.
Model Identification:The numbers "88" and "95" directly indicate their different capacity tiers.
6. Important Considerations
Professional Selection:Must be selected by a qualified engineer based on the system's actual cooling load and operating conditions to avoid under-sizing or over-sizing.
System Cleanliness:During installation, it is essential to ensure the system is clean and dry to prevent contaminants and moisture from damaging the compressor.
Correct Refrigerant:Use only specified lubricants and refrigerants. Special adjustments may be required when retrofitting systems (e.g., switching from R404A to R448A).
Summary
The Copeland ZB88KQ is a stable, efficient, and cost-effective medium-capacity commercial scroll compressor. As a key member of the ZB series, it holds a significant market share in the small to medium commercial refrigeration sector. It is highly regarded for its excellent cost-performance ratio and the high reliability associated with the Copeland brand.
