I. Product Overview
II. Product Features
|
Complete specifications The product lineup offers a comprehensive range of models and specifications, including single-cooling, cooling-and-heating, heat-pump, 100% fresh-air, and clean-air series. A variety of functional modules are available, enabling convenient implementation of multiple functions such as cooling, heating, humidification, dehumidification, reheat, air purification, noise reduction, and energy-efficient fresh-air ventilation—without the need for dedicated fresh-air handling units or separate ductwork. This fully meets stringent indoor air-quality requirements. The products are widely suitable for central air-conditioning systems in areas where water-system installation is impractical or where water resources are scarce. |
Space-saving The unit is designed for rooftop and outdoor courtyard installation, featuring protection against direct sunlight, corrosion, and heavy rain, eliminating the need for a dedicated machine room and preserving indoor usable space. |
|
Subcooling Design The chiller unit is equipped with a subcooling loop at the bottom of the condenser, which increases the subcooling of the refrigerant liquid during cooling operation, thereby enhancing cooling capacity and efficiency. This design also more effectively addresses the challenge of incomplete defrosting caused by ice formation at the bottom of the coil during heating mode. |
|
Multi-level control Parallel compressor configuration combined with hot-gas bypass enables multi-level capacity modulation, preventing frequent start-stop cycles of the compressors and extending the service life of the unit. |
Low air leakage rate The adoption of a stepped multi-seal structure and a continuous, seamless elastomeric sealing surface—two key technologies—ensures that the unit can |
|
Stainless steel integral frame The frame is designed with a steel–aluminum composite structural profile, offering 83.7% higher strength than conventional aluminum alloy frames and 63.9% higher strength than conventional steel frames. It combines the high precision and aesthetic appeal of aluminum alloy frames, with a cabinet deformation of 0.68 mm/m at 1,000 Pa and 1.55 mm/m at 2,500 Pa—significantly better than the national standard requirement of <4 mm/m at 1,000 Pa—and meeting the highest D1 rating specified in the European standard EN 1886:2007. |
|
Stainless steel integral water tray The evaporator section of the unit features an integral water pan with a carefully designed tilt angle, ensuring that the lowest point of the drain outlet facilitates rapid condensate discharge without pooling. The design also provides excellent thermal insulation and high structural strength. |
|
Brand Accessories The unit’s key components—including the compressor, electronic expansion valve, heat exchanger, centrifugal fan, axial fan, humidifier, electric heater, and electrical components—are all sourced from well-known international or domestic brands, ensuring stable unit performance and energy-efficient, safe, and reliable operation. |
|
Complete unit control Equipped with industrial-grade microcomputer control and powerful computational capabilities, the unit enables real-time monitoring and analysis of various operating parameters, ensuring optimal performance at all times, while also supporting remote communication and other advanced features. |
