Brief
The Energ z High Joiner (30KW-100kW) air-cooled fixed frequency series provides refrigeration solutions for medium- and large-sized
computer rooms, communication rooms, and industrial control rooms. As an important part of a data center, KHJA (30KW-100kW) fully meets the cooling requirements of the data center. The high AEER design and intelligent group control effectively reduce the PUE value of a machine room to ensure the all-weather efficient and reliable operation of the machine room around the clock.
Application
- Medium- and large-sized data centers
- Monitoring rooms, distribution rooms and battery rooms
- Industrial control room s and precision machining equipment
Customer Value
Highly efficient – saving money
- Fullinverter technology, achieving step-less regulation of 10~100% cooling capacity, and high matching of dynamic loads.
- Adopting a highly efficient EC backward centrifugal fan, the air volume can be continuously adjusted to quickly match the cooling load of the machine room
- Adopting a highly efficient V/A evaporator with a large heat exchange area to achieve fast and efficient refrigeration.
- The unit adopts a modular design, which reduces the difficulty of installation and is flexible in disassembly and assembly. There is no need to cut copper pipes when disassembling, reducing transportation costs.
- The electric control box features a pull-out design, making it easy to maintain
- Dual electronic expansion valve design, variable capacity intelligent low-load dehumidification, accurate dehumidification under load conditions as low as 10%, wide adjustment range, precise cooling, efficient and energy-saving.
- Adopting a DC inverter compressor and soft start to reduce the impact on the power distribution system
- Under the same heat dissipation capacity, a compact outdoor unit can effectively save up to 38% of floor space.
Highly intelligent – time-saving
- 7″ true color touch screen, multi-level password protection, hierarchical authorization management, along with intelligent
management and control - Standard RS485 communication interface, remote monitoring, optional SNMP and TCP/IP interfaces, and improved
interconnectivity - Powerful control system, centralized control of up to 32 units, automatic switching between active and standby mode, timing
surveillance and automatic failsafe, along with an optimized ownership cost - Intuitive display of temperature and humidity curve, graphic display of the operational status of each component, improved
operation and maintenance efficiency - Deep in-system detection, alarm, protection functions, large-capacity storage for alarm records, no less than 500 entries of
historical alarms, and reduced operation costs, maintenance costs and application risks
Highly reliable – worry-free
- Each unit has been subjected to strict on-line operational tests 24 hours x 365 days operation and a ten-year lifespan design, ensuring high reliability and low maintenance costs.
- Ultra-wide operating condition (outdoor: -35°C to 45°C), wide scope of applications
- Equipped with a belt-type water leakage sensor as standard, which can detect water leakage and provide real-time audible and visual alarms to ensure the safety of the machine room in all aspects.
- The unit is compatible with both sinking fan air supply and ordinary downward air supply, and can be flexibly applied in multiple scenarios.
