Product Specifications:
Cooling Capacity: 264~1596 kW
2. Heating Capacity: 270~1,535 kW
3. Compressors: Semi-hermetic twin screw compressors, each unit equipped with 1-2 compressors; compressors in dual circuit system units can serve as backups for each other.
4. Environmental temperature range: -20℃ to 48℃ in refrigeration condition, -10℃ to 43℃ in heating condition.
5. Refrigerant: Uses environmentally-friendly refrigerant R134a, which has no ozone-depleting effects on the atmosphere.
6. Service Life: The compressor features a high-load-resistant design, with a service life of ≥50,000 hours.
Performance Features:
1. Energy-Saving and Efficient: Equipped with innovative self-regulating electronic expansion valve control technology, the unit can meet user demands in energy-saving mode within its operating range. During full-load operation, the energy efficiency ratio exceeds 3.4 and the IPLV value reaches above 4.1, earning an energy-saving certification. Suitable for energy-saving policy requirements, it saves energy and costs.
2. Stable and Reliable: Each unit employs 1 to 2 compressors, with each compressor equipped with an independent refrigeration circuit, ensuring stable system operation. The dual-circuit system's backup compressor guarantees continuous operation, and multi-compressor units can automatically balance the running time of each compressor, extending the overall system lifespan. Utilizing 11 high-efficiency bearings, a proprietary reverse bearing, and a balancing drum design, the lifespan of the compressor is effectively enhanced, ensuring the unit's stability and reliability.
3. Wide Operating Range: The unit boasts a broad temperature operating range, enabling efficient cooling and heating in various environmental temperatures to meet year-round air conditioning needs. Whether it's the cold winter or the hot summer, it operates stably and efficiently.
4. Low Noise & Eco-Friendly: Utilizes eco-friendly refrigerant R134a, ensuring efficient cooling without harming the ozone layer, fully compliant with the Montreal Protocol, contributing to environmental protection. The full-film evaporator significantly enhances heat exchange efficiency, reduces refrigerant charge, and promotes greener practices. Standard equipment includes low-noise fans and a noise-reduction box for compressors, effectively lowering the operational noise of the unit, ensuring a comfortable and quiet environment.
5. Cost Savings: By increasing the temperature difference between the inlet and outlet water, reducing the pump flow rate and head, the goal of lowering the pump power and overall system energy consumption is achieved, conserving water resources and saving operation costs. The unit installation is flexible, requiring no dedicated machine room or purchase of equipment such as cooling water towers and cooling pumps. The electrical and main unit are designed as an integrated system, reducing additional investments like electrical control cabinets.
