1. dual-mode energy-saving refrigeration:

Air-conditioning unit with an active cooling and natural cooling two kinds of practical cooling method, through the main control panel and a number of internal and external temperature sensors of the automatic computer control, according to base stations, indoor and outdoor room temperature requirements and changes, automatic switching equipment, refrigeration methods : When the outdoor temperature is below 5 degrees above room temperature setting, equipment, switch to natural cooling mode, pumping more cold air outdoors by strict filtering into the room to cool; when the outdoor temperature and indoor temperature difference of less than 5 degrees, then switch to Active cooling mode, the compressor starts, for indoor cooling. Using dual-mode cooling, you can take full advantage of the natural conditions on the indoor temperature control, to achieve energy efficiency and extend the service life of air conditioner compressors, refrigeration systems aim to effectively reduce operating costs and operation and maintenance costs.
2. automatic DC Emergency:
The machine in base stations, room AC power, may automatically use the DC 24V or 48V battery to maintain operation within the fan does not stop at the same time, if the sensor measured at room temperature lower than the outdoor temperature, natural cooling valves automatically open, the introduction of external air-cooled interior environment, prevent the base station, room after room temperature a sharp increase in power caused by damage to electronic equipment.
3. power-off after the call from the start:
Power after the call, the machine automatically re-starts, and return to the pre-set parameters of power running, power-off does not change before and after the working state.
4. remote monitoring:
The standard equipped with RS485 communication port, directly connected with the host computer can realize the primary alarm; such as connecting wired / wireless modem, and install high-level monitoring software, you can achieve the high-level monitoring, real-time monitoring, remote parameter adjustment to change the operating settings, Multi-mode device testing and fault alarm and remote troubleshooting features such as a substantial increase operational reliability and to achieve the maintenance simplicity.
5. compressor automatic protection
Automatic compressor start times for the "6 times / hour, to extend the service life to 10 years.
6. comfort features
Personnel on the base station, engine room equipment, maintenance, press the button, comfort, compressor forced to start lowering the indoor temperature to 24 degrees, suitable for human comfort. 1 hour, the machine automatically restore the original settings, adjust indoor temperature of the working environment for the device.
7.a variety of sensors optional (door sensors, smoke sensors) to achieve centralized monitoring.
8. wind output
The machine room air volume up to 1200 cubic meters / hour to ensure that all parts of room temperature uniformity to meet the equipment and job requirements.
9. the working temperature
The machine can be at ambient temperature -40 ~ +55 degrees Celsius within the normal work environment characteristics suitable for various regions of the country.
