base station air condition unit Details

◆ High energy-efficiency ratio: Adopt high-efficiency fully-enclosed rotor or scroll compressor, adopt external thermal expansion valve with extremely stable performance, and carefully design high-efficiency heat exchanger. After a large number of matching experiments, the products have high performance. Coefficient, energy efficiency ratio is above 3.0, which has unparalleled energy saving and consumption reduction advantages.

◆ High sensible heat ratio: In a relatively closed base station or computer room environment, electronic equipment operates to release a large amount of sensible heat. According to this situation, the unit is carefully designed with large air volume and small roasting characteristics, and the sensible heat ratio reaches more than 85%. Quickly cool the environment without leaving the room too dry.
◆Lightning protection function: The air-conditioning equipment has good lightning protection measures, which meets the requirements of YD5098-2005 for the protection ability of lightning protection and overvoltage;
◆Remote monitoring: The unit provides RS-485 communication interface, which can communicate with the remote monitoring computer with full parameters. It has two control modes, local and remote, with three remote functions:
Telemetry: remotely detect the temperature and humidity in the equipment room.
Remote signalling: remotely read air conditioner operating status parameters and fault information.

Remote control: can remotely control the switch of the air conditioner and the setting of related parameters.
◆Self-starting after power failure: In order to adapt to the unstable state of the power grid in China's cities and villages, the self-starting function during power-down is specially designed. When a call comes in shortly after a power failure, the unit remembers and maintains the air conditioner's operating status before the power failure Run automatically.
◆ Dual-machine switching: The dual-machine switching function is very suitable for unattended base stations in some remote places. For safety considerations, the user will adopt the design of the main machine plus the standby machine, which can realize the alternate cooling operation of the two machines and achieve the need to extend the service life. The most important thing is The problem is that when one air conditioner fails, the other one will be put into operation immediately until the problematic unit returns to normal.

◆ Low-temperature refrigeration: The base station or the equipment room has a large amount of heat that needs to be cooled throughout the year. Refrigeration and air conditioning are designed and matched according to summer temperature. Refrigeration operation in the transition season and winter environment will seriously endanger the life of the unit. Special design has been carried out, and countermeasure accessories have been added to enable the product to operate stably and reliably in cold environments.

◆Microcomputer control: The special air conditioner for the base station uses a specially developed large-screen Chinese character text controller. The highly secure and reliable microcomputer controller has powerful function driving capabilities and communication ports, which can realize multi-machine networking and remote centralized monitoring data exchange capabilities to ensure control. 6, foolproof use of networking, saving base station operation and management costs.
◆ Full-automatic fault diagnosis: The base station-specific air conditioner has a variety of automatic fault diagnosis and code display functions, and can be transmitted to the remote monitoring unit through the communication port, so that maintenance personnel can know the fault location at a glance, which is convenient for maintenance and maintenance.
