2. Product Description
Product Introduction
The computer room air conditioner is a special air conditioner designed by Guangdong Yibike Energy Technology Co., Ltd. for IDC computer rooms and communication base stations that operate non-stop 24 hours a day, 365 days a year. The units are stable, safe and reliable, ensuring that the equipment in the computer room operates in the most suitable environment for a long time.
The unit is designed with a frame structure, and all components can be conveniently repaired or replaced from the front and sides of the unit. But to ensure the cooling effect, the side and back of the unit should be more than 400mm away from the wall. Unit air supply mode: Front air supply.
Product features
The unit has control functions for cooling, heating and dehumidification, temperature and humidity can be set, and the system can work according to the set indoor temperature and humidity state. The control of each function is guaranteed within the set control points and precision control range.
Temperature adjustment range: +16 ° C to +40 ° C, temperature adjustment accuracy: 1 ±° C;
Humidity adjustment range: 20% to 95%RH, humidity adjustment accuracy: 5%RH.±
1) Refrigeration
It uses a direct expansion refrigeration cycle, which is highly energy-efficient, reliable and has low operating costs, in line with the "green and environmentally friendly" requirements.
2) Dehumidification
The unit automatically controls the fan speed according to the room requirements, thereby precisely controlling the dehumidification capacity of the unit, which can greatly improve humidity control accuracy while dehumidifying quickly.
3) Reheat (optional)
When the system needs dehumidification, the unit can start the electric heating to compensate for the cooling capacity as required. The unit is equipped with a PTC electric heater and has overheat protection.
4) Humidification (optional)
Use an electrode humidifier to achieve a humidification output of 30% to 100%.
5) Group control
Supports multi-unit networking for centralized control, and also has rotating and backup functions.
6) Remote monitoring
Supports remote monitoring, provides RS485 interface, supports MODBUS protocol. It has three remote functions: remote measurement, remote control, and remote signaling.
7) Alarm protection
Fan failure alarm, electric heater overload alarm, humidifier failure alarm, phase sequence protection alarm, system high/low pressure protection alarm, filter clogging alarm, temperature too high/too low alarm, etc.
8) Other functions
The unit has functions such as manual/automatic operation control, shift and backup, fault self-diagnosis, fault alarm record storage, power loss storage/automatic recovery/power-on auto-start, multi-level password, etc. It can also record the cumulative working time of the compressor, fan, humidifier and heater.
