Intelligent control
The industrial controller is used to monitor and analyze various operation parameters of the unit in real time, so that the unit is always in good operation state. The system is equipped with a full Chinese display with friendly interface and convenient operation. It has RS-485 and RS-232 physical interfaces, which can realize networking group control of multiple hosts and networking communication with intelligent devices with open communication protocols. It also has functions such as remote communication and multi-level password protection.

Security protection
 • Power supply protection: power supply phase loss, reverse phase protection, overvoltage protection and undervoltage protection;
 • Compressor protection: prevent motor overheating, overload, frequent starting, oil level protection, high exhaust temperature protection;
 • Pressure protection: the condenser is equipped with a safety valve for protection against too low low pressure, too high high pressure and low suction and exhaust pressure difference;
 • Other protections: low water temperature protection, low water flow protection, sensor failure, etc.

Environmentally friendly refrigerant
In order to protect the ozone layer and reduce the greenhouse effect of the atmosphere, the unit uses R134a environmental protection refrigerant, the ozone depletion potential value is 0, safe, non-toxic, non-flammable, green and environmental protection, which adapts to the current international environmental protection development trend.

Cloud control technology
Unit cloud control technology is a reliable guarantee to realize energy saving, money saving and modernization in the process of system operation and management, which has the functions of remote network control, system energy-saving operation, cold and heat metering, power consumption statistics, remote fault alarm, remote parameter display and setting, real-time picture display, remote start and stop equipment, etc. It can strengthen the energy-saving operation management of the whole central air-conditioning system from the control of each air-conditioning area of the building.

Structural optimization technology
The unit is compact in structure and occupies a small area;
During field installation, only the evaporator and condenser water pipes and power supply wiring need to be connected.

Silencing and noise reduction technology
The fan impeller is optimized by professional flow field software to ensure that the impeller has good aerodynamic performance.
While ensuring the low-noise operation of the fan, a larger air volume is obtained to improve the heat exchange effect on the air side; the whole machine is equipped with a standard protective plate to improve the appearance and further reduce the noise;
