DC48V Series telecom base station Precision Air Conditioner
Introduction:
I. Product description
DC48V series of Telcom shelter precision air conditioning is specially designed for the internal circulation cooling of the telecom shelter, combined with the many advantages of current's precision air conditioning products and the latest technology, the development of high-performance precision air conditioner. The unit adopts large air volume, small enthalpy difference,365 days *24 hours all-day continuous operation design, with high efficiency, energy-saving, stability, long life, and other characteristics.
II. Performance characteristics
Energy efficiency
1, Large air volume, small enthalpy difference design, suitable for heat dissipation characteristics of equipment in the cabinet
2, Adopt internally threaded tube, high-efficiency fin evaporator, higher heat transfer efficiency than traditional coil
3, External balanced thermal expansion valves are used to accurately regulate refrigerant flow by taking temperature and pressure signals DC variable frequency compressor, variable capacity compression technology, dynamic refrigeration output, reduce the number of starts and stop, improve system reliability
The centrifugal fan with high efficiency and high reliability has the advantages of large air volume, long-distance air supply, direct transmission, and convenient maintenance
4, Close to the rack installation, closer to the heat source, sustainable monitoring of changes in heat load and immediate energy-efficient refrigeration
5, Adopt the primary effect nylon filter, with large ventilation, low resistance, strong dustproof performance, long service life, can be repeatedly cleaned and used
Flexible refrigerating capacity design: can automatically adjust cooling capacity and air volume output with the change of equipment heat load to meet the precise cooling temperature and humidity
6, Design of return air in front air supply, optimizing air distribution and maximizing refrigeration efficiency, higher refrigeration efficiency, and more energy saving
7, R410A, R134A environmentally friendly refrigerants that do not destroy the ozone layer and are more efficient in refrigeration, following environmental principles
8, Has a standard RS485 monitoring interface and uses the Ministry of Industry and Information Technology standard communication protocol
9, Standard 19-inch rack mounting, in-room machine mounted on the rack, airflow organization in accordance with the design requirements in the cabinet
The outdoor fan adopts full speed control with no pole to ensure that the system runs healthier, more energy-efficient and lower noise
Ability to adapt
1, Ultra-wide input voltage range with multiple power protection functions
2, Long life design, high stability, low maintenance,24 hours a day,365 days a year
3, Strong environmental adaptability: the condenser standard configuration meets the outdoor temperature environment of -15℃~+45℃, within which the unit guarantees continuous refrigeration. The condenser can be provided to meet the lower outdoor temperature environment, and the low-temperature condenser can meet the outdoor temperature environment of -34℃+45℃ to ensure the refrigeration demand of the winter machine room in the northern region
