Air Conditioning System
Air conditioning method: forced ventilation internal circulation, balanced temperature regulation (BTHC), this method in the case of continuous operation of the refrigeration system, the central control system according to the collected temperature signal inside the box for amplification, analog, digital conversion, non-linear After calibration, it is compared with the set value (target value) of the temperature, and the deviation signal obtained is subjected to PID calculation, and the adjustment signal is output, and the output power of the heater is automatically controlled, and finally the temperature in the box reaches a dynamic balance.
Indoor air circulation device: stainless steel centrifugal fan and air guide plate ensure uniform air supply, uniform indoor temperature and adjustable indoor wind speed.
Air heating method: finned radiator tube high-quality nickel-chromium alloy electric heater heating.
Air cooling method: multi-stage finned air heat exchanger.
Refrigeration method: Two sets of Emerson Copeland Scroll fully enclosed compressors, one for use and one for preparation, environmentally friendly refrigerant R404A.

Software playback function
Historical data can be played back and converted into ACCESS or EXCEL format files. The controller can store 600 days of historical data (under 24-hour operation), which can be viewed directly in the machine. The test program is compiled through the PC special software and saved to the U disk, and then the test program is called out from the U disk and stored in the controller; the program in the controller can also be transferred to the U disk. The test program is realized through the network interface The two-way transmission between the PC and the controller directly transmits the recorded test curves and data. The test curve data recorded in the controller can be transferred to the U disk. Directly through PC special software
Connect to display and print test data and curves. Or convert the recorded data into an Access data file read by Microsoft office.

Safety protection measures:
The equipment provides the following safety protections, and sounds and lights alarms when a fault occurs:
1. Three-phase power supply lack phase protection; 2. No fuse switch protection;
3. Heater short circuit protection; 4. Blower motor overload protection;
5. High pressure protection of refrigeration system; 6. Overload protection of compressor;
7. Protector to prevent dry burning; 8. Three-color lamp operation instruction;
