27kW Room Cooling–front-blowing, EC fan, inverter unit with 7-inch display, R410A

Diversity：

• Each cooling capacity range offers three configuration types: single cooling, single cooling with electric auxiliary heating, and constant temperature and humidity. Each configuration features an indoor EC fan, an electronic expansion valve, a high-performance inverter compressor and the environmentally friendly refrigerant R410A
• The maximum cooling capacity ranges cover seven cooling capacity bands: 5.5 kW, 8.5 kW, 13.5 kW, 17.5 kW, 22.5 kW, 27 kW and 32 kW

High reliability

• Designed for industrial-grade, year-round, uninterrupted operation with a service life of over ten years, ensuring continuous operation throughout the year
• Both the indoor and outdoor unit fans feature metal blade designs, offering excellent stability and a long service life
• Equipped with an automatic restart function; upon power restoration, the unit automatically resumes the operating state it was in prior to the power cut
• Fitted with a fully enclosed, metal-welded refrigerant circulation pump with no seals whatsoever, ensuring zero leakage

Energy-efficient and high-performance

• The unit’s annual energy efficiency ratio (AEER) exceeds 4.0, meeting Grade 1 energy efficiency standards.
• Featuring a high-efficiency, energy-saving design with high airflow and a small enthalpy difference, it offers a high sensible heat ratio, making it highly compatible with the sensible heat generated by primary equipment in server rooms and equipment rooms.
• When used in server rooms, compared to domestic air conditioning systems, it offers higher energy savings and superior cooling performance.
• It utilises variable-capacity refrigerant pump control technology to precisely regulate refrigerant flow, maintaining optimal cooling capacity. The outdoor unit fan employs stepless speed control, which not only saves energy but also reduces noise levels.
• Featuring large-surface-area evaporators and condensers, the indoor unit’s return air grille area has been increased by 15 per cent, resulting in high cooling efficiency and a high energy efficiency ratio.
• Equipped with EC fans in the indoor units, electronic expansion valves and high-performance inverter compressors, the system provides precise regulation, delivering greater efficiency and energy savings under partial load conditions.
• It utilises the environmentally friendly refrigerant R410A, which is both eco-friendly and highly efficient.

Intelligent Management

• Features a 7-inch high-definition touchscreen display; all operational, configuration and fault information is displayed in Chinese,
• providing a clear and intuitive view of the operating status and facilitating maintenance and management.
• The intelligent management system displays the unit’s cooling factor and cumulative carbon emissions, making its operational efficiency, energy savings and carbon reduction immediately apparent.
• It employs an intelligent PID predictive control algorithm, characterised by high control precision.
• It features multi-level password protection, enabling access control. It includes functions for tracking the operating hours of key components and providing maintenance reminders. It is equipped with a self-diagnostic function, facilitating rapid maintenance. It comes standard with an RS485 intelligent communication interface, and the communication protocol is provided free of charge.
• It is fitted with dedicated primary and standby interfaces, enabling group control functions, including automatic primary-to-standby switching and automatic rotation of duty between units.

High Adaptability

• Suitable for use in most regions of the country, operating normally within a range of -15% to +10%
• High environmental adaptability: Operates normally within an outdoor ambient temperature range of -40°C to +45°C without the need for low-temperature components or extension kits.
• Wide voltage tolerance: Three-phase units can accommodate voltage fluctuations ranging from 380V -15% to +10%, whilst single-phase units can accommodate
• The units are equipped with indoor EC fans and high-performance inverter compressors to prevent compressor burnout caused by reversed phase sequence
• Far-infrared humidification system, featuring rapid humidification and strong adaptability to water quality, compliant with the national CCC mandatory certification

High Availability

• The air filter can be rinsed directly, and key components are removable for maintenance. The outdoor unit is compact, saving floor space.
• The unit features a compact design with full front-access maintenance; no return air space needs to be reserved at the sides, making maintenance convenient and installation more flexible.
• For 5.5kW–22.5kW units, the air-cooled condenser is seamlessly integrated with the natural cooling energy-saving module comprising the refrigerant pump, resulting in a highly compact design and simple installation.
• Units ranging from 5.5 kW to 22.5 kW are pre-charged with refrigerant and fitted with quick-connect fittings, enabling rapid connection of the indoor and outdoor units and prompt commissioning
• The air-cooled condenser coils in 5.5 kW to 22.5 kW units feature a ‘U’-shaped design, enabling a larger heat exchange area within a smaller space.
• The 27 kW and 32 kW units feature a highly compact design; when paired with the refrigerant pump energy-saving unit, the overall height is less than 1 m and the floor space required is just 0.15 m², allowing for greater installation flexibility
