The single-chip microcomputer control system of refrigeration (refrigeration) equipment has built-in protection functions, automatically detects changes in the external environment, and realizes multiple operations: compressor start and stop control; fan start and stop control; power supply operation indication; fault status indication; fire alarm signal Output etc.

The refrigeration (freezing) equipment adopts the DDC (Direct Digital Controller) control mode, which can automatically realize the switch control of cooling, heating, humidification, and dehumidification according to the temperature (humidity) detected by the supply air temperature and humidity sensor to make the supply air temperature The humidity is kept within the required range. It can collect and display various analog parameters on site, set and modify various parameter values, record real-time alarm information, and have the function of switching between manual and automatic operation modes. The operating frequency of the inverter can be automatically adjusted according to the temperature and humidity value, the pressure in the pipeline and other parameters, thereby changing the fan speed, realizing stepless air volume adjustment, and achieving the purpose of accurately controlling temperature and humidity, air pressure, and carbon dioxide content.

The refrigeration (freezing) equipment adopts PLC (programmable controller) control mode, which is reliable in operation, convenient in use and maintenance, strong in interference protection, and meets the control requirements of different occasions; the unit is equipped with manual or automatic functions to achieve environmental reliability Accurate system, with various protection functions, can also achieve unit joint control, and can be connected to a general open protocol, and easily realize the group control function (support RS485, RS232, ModBUS, LonWORKS, BacNET and IP protocol SNMP).

It is equipped with a variety of displays to choose from, which realizes the function of unit operating data display, parameter setting, fault alarm, diagnosis and query, making the user operation more convenient and worry-free.

GTAIR operation management technology is a digital intelligent control system carefully developed by the enterprise. It is reliable, precise and powerful. It is composed of a Chinese graphic microcomputer controller, remote monitoring technology components, electrical control actuators and induction detection mechanisms, which can ensure the safety of refrigeration equipment. Stable operation and realization of intelligent PID operation management, making user operation more convenient and worry-free.
