1. Instead of using a household wall-mounted air conditioner in a granary, adopt a horizontal all-in-one machine structure design to reduce the connection and installation links of copper pipes connecting the internal and external machines. You only need to turn on the power supply to use it.

2. Using PLC automatic control, the user can set the switch temperature according to the warehouse temperature control requirements, and the automatic control system can automatically switch on and off the machine.

3. The unit has large air volume, long range of cold air (up to 30 meters), small structure and light weight.

4. The whole machine is made of anti-corrosion aluminum alloy, which is beautiful and elegant, corrosion-resistant, and is not afraid of corrosion by chemicals. There is no need to protect the unit during grain fumigation.

5. Based on the judgment of the temperature difference between indoor and outdoor, when the outdoor temperature is lower than the indoor temperature at night, fresh outdoor air is automatically introduced to cool down without starting the compressor for refrigeration, which is more energy-saving.

6. Manual and automatic dual control, the automatic control system can be connected with the intelligent ventilation system of the grain depot.
