DJA 3.5KW-12.5KW

Category

With the rapid development of big data and cloud computing, small node computer rooms are built to support network access and basic IT applications, which greatly promotes the development of micro module intelligent computer room products.Deeray DJA series rack type air conditioner is a cabinet level temperature control product specially designed for integrated cabinet, micro module or high heat density data center. The indoor unit is designed according to the installation size of a standard 19 inch rack, which can be placed close to the heat source in the cabinet and integrated with the cabinet communication equipment. The product structure is compact and beautiful, which can accurately handle the high sensible heat produced by the equipment in the cabinet and effectively prevent local hot spots, It can reduce the distance between supply and return air, improve the return air temperature, and improve the energy efficiency ratio. It has significant energy saving effect and effectively helps the continuous development of green data centers.

Product advantages

High end configuration

Efficient variable frequency compressor, with the refrigeration capacity of 30% - 100% stepless adjustable, and with the ultra precision PID control technology, the temperature control is more accurate.

The well-known brand EC centrifugal fan can adjust the air volume steplessly, adjust the air volume output ratio on demand in real time, improve the control accuracy and reduce the fan power consumption.

The electronic expansion valve is equipped as standard, with fast adjustment speed, wide adjustment range, smooth adjustment of throttle opening, and accurate adjustment of unit refrigerant flow.

Outdoor fan motor can operate steplessly according to the pressure of the refrigeration system, realizing 25% - 100% wide voltage speed regulation control, making the pressure of the refrigeration system more stable, and reducing the energy consumption of the fan.

The refrigeration system R410A environmental friendly refrigerant design conforms to the modern environmental protection concept.

Safe and reliable

Very wide power grid adaptability, which can meet the voltage range of ± 20%, adapt to various harsh power grid environments, and reduce the fault risk caused by the wide range of power grid voltage fluctuations.

Multiple drainage and anti backflow design to eliminate cabinet flooding.

Equipped with high and low pressure sensors, it can conduct intelligent self detection and intelligent early warning of refrigerant capacity to ensure the safe operation of the refrigeration system.

High and low pressure switches are configured to provide alarm when high and low pressure exceeds the range.

PTC electric heater is selected and equipped. The semiconductor material has positive temperature coefficient characteristics to avoid redness on the surface of the electric heater. The electric heating over temperature protection device is equipped with multiple safety protections to ensure safe operation of the electric heating system.

Highly intelligent

Efficient frequency conversion compressor, ultra precision PID control technology, and higher temperature and humidity control accuracy.

Unique vibration compensation algorithm is adopted to realize wide frequency operation of the unit.

The safe and reliable anti condensation algorithm can avoid the wind and fog and ensure the safe operation of the server.

Convenient installation and maintenance

The standard is designed according to 19 inch cabinet, which can be installed in any standard cabinet.

Fan side and the whole machine are designed with plug-in terminals, which makes the whole machine easy to maintain and fast to install; Small floor space, 100% full front maintenance.

Cooling pipes are connected with quick connectors.
