||
| Air conditioning system | |||
| Features | Regulation and control: forced convection and humidity regulation of the fan blades | ||
| Air circulation | High-power fan driven by external motor with stainless steel shaft, external fan motor;
The air is driven by a motor and fully flows through the heater. After being fully heated to the required temperature value, the air circulates inside the box, and the test piece is exchanged through convection. |
||
| Fan motor | Low voltage asynchronous high temperature resistant long axis motor | ||
| Centrifugal wind wheel | Multi-blade centrifugal circulating fan, aluminum alloy blades | ||
| Heating humidifier | Armored cross tube heater, PID+SSR control, equipped with independent over-temperature protection temperature switch
After the heater is energized, the surface temperature will increase. The temperature of the convective air increases after passing through the heating wire, which expands the heat to the air in the box and the test piece, and plays the role of heating and heating. The heating power is precisely controlled by the PID algorithm, and the output power is adjusted through the solid-state relay |

| Pressure protection system | Automatic exhaust and pressure relief when the pressure in the box exceeds the maximum working value
1) Double protection of independent mechanical pressure gauge and upper limit pressure setting in controller 2) Safety relief valve (automatic pressure relief valve, can be manually controlled) |
||
| Door lock protection | The position sensor judges whether the box door is closed in place and locked, otherwise the equipment cannot run | ||
| Main switch | Equipment leakage protection, overload and short circuit protection | ||
| Control circuit | Overload and short circuit protection | ||
| Alarm | When the above protection occurs, the equipment stops running, and sends out an audible and visual alarm. At the same time, the fault location and its cause and solution are displayed on the instrument | ||
