industrial air conditioner for 5G base station (gNodeB)

The 5G base station air conditioner is an air conditioning system that automatically controls the cooling and heating of the 5G communication base station (computer room), which is the current development trend of domestic and foreign communications. State monitoring and supervision, through high air-conditioning energy efficiency and quality requirements to ensure that the base station (computer room) has good stability, safety, and economy. In addition to ensuring the normal operation of communication equipment, it can achieve the purpose of energy saving and consumption reduction. In view of the particularity of the distribution area of 5G base stations (computer rooms), functions such as high humidity dehumidification, emergency ventilation, and energy saving of fresh air cooling linkage have been added.

industrial air conditioner for 5G base station (gNodeB) Details

◆High energy efficiency ratio: The product adopts high-efficiency fully enclosed rotor or scroll compressor, adopts extremely stable external balance thermal expansion valve, carefully designed high-efficiency heat exchanger, and after a large number of matching experiments, the product has a high performance The coefficient of performance and the energy efficiency ratio are above 3.0, which has significant advantages in energy saving and consumption reduction.
◆High sensible heat ratio: In a relatively closed base station or computer room environment, the operation of electronic equipment releases a large amount of sensible heat. According to this situation, the unit is carefully designed to have the characteristics of large air volume and small enthalpy difference, and the sensible heat ratio can reach more than 85%. Quickly perform environmental cooling without keeping the room too dry.
◆Heat and cold dual function: The dedicated air conditioner has the unique cooling and heating independent preset temperature control function. When the base station is used in cold areas, a small amount of heating and preheating operation is required in winter. Each control temperature can be set separately. Automatic mode switching operation according to the indoor temperature unmanned control.
◆Annual cooling: The base station or computer room generates a large amount of heat and needs to be cooled throughout the year. The cooling and air conditioning are designed to match the summer temperature. The cooling operation in the transitional season and winter environment will seriously endanger the life of the unit, so Wellcome is dedicated The air conditioner is specially designed and countermeasure accessories are added to enable the product to perform stable and reliable cooling in cold environments.
◆High humidity and dehumidification function: When the base station is in the south, Southeast Asia or Jianghai region, the surrounding environment temperature is high, and high humidity is unavoidable in the station. The proprietary air conditioner has professional-level deep dehumidification function, and the optional dehumidification module components can achieve high Humidity and dehumidification function.
◆Fresh air cooling function: The base station environment temperature control can be equipped with energy-saving operation mode. When the air-conditioning system is equipped with a low-temperature fresh air cooling system or equipment, the dedicated air-conditioning control can be automatically switched and managed, and humidity management can be taken into account to achieve energy saving, safety and reliability. Systematic operation.
◆Emergency ventilation function: A single air conditioner is installed in the base station. When there is an optional fresh air refrigeration system, when an air conditioner fails to repair itself, the special air conditioner can be linked with the fresh air equipment to provide emergency ventilation function and realize emergency safety treatment.
◆Dual-machine switching: The dual-machine switching function is very suitable for unattended base stations in some remote places. For safety reasons, users will adopt the design of main machine plus standby machine, which can realize dual-machine rotation operation, high-load compensation management operation, and fault linkage Operation ability, so as to realize the high safety and reliability of the base station.
◆Auto-start after power failure: In order to adapt to the unstable power grid or sudden power failure, the dedicated air conditioner has a power-on self-start function. The unit remembers and maintains the air conditioner's running status before the power failure and automatically starts operation.
◆Lightning protection function: the special air conditioner can be equipped with lightning protection measures, which meets the requirements of YD 5098-2005 for lightning protection and overvoltage protection;
◆Remote monitoring: The unit provides RS-485 communication interface, which can communicate with the remote monitoring computer in full parameters. It has two control modes, local and remote, and has three remote functions:
Remote measurement: It has the ability to remotely detect the temperature and humidity in the computer room.
Remote signaling: remotely read the air conditioner operating parameters and fault information.
Remote control: It can remotely control the switch of the air conditioner and the setting of related parameters.
◆Microcomputer control: The base station special air conditioner adopts a specially developed large-screen Chinese character text controller. The high-safety and reliable microcomputer controller has powerful function driving capabilities and communication ports, which can realize the centralized monitoring data exchange ability of multi-machine networking to ensure control , The use of networking is foolproof, saving base station operation and management costs.
◆Fully automatic fault diagnosis: The base station special air conditioner has a variety of automatic fault diagnosis and code display functions, and can be transmitted to the remote monitoring unit from the read-through port, so that the maintenance personnel can know the fault location at a glance, which is convenient for maintenance and maintenance.
◆Quality assurance and testing: Wellcome 5G base station air conditioners are designed, developed and manufactured in accordance with the ISO9001 international quality certification system. Each component of the product undergoes strict inspection before installation to ensure that each unit has undergone strict testing and only qualified before leaving the factory.
