AI Technical Summary
When the door of a refrigerated display case is opened, the internal temperature of the refrigerated display case rises, which affects the preservation of all vegetables. Furthermore, the accumulation of ethylene and CO2 causes vegetables to ripen prematurely, and the energy consumption is high.
It adopts an independent cold storage compartment design, with each compartment equipped with an independent cabinet door and refrigeration equipment. Combined with fans and controlled atmosphere components, it uses activated carbon plates to absorb ethylene and CO2 in the air to achieve air circulation and gas purification.
It achieves independent temperature control of the cold storage compartment, reduces energy consumption, and prevents premature ripening of vegetables through air circulation and gas purification, thus maintaining the freshness of the vegetables.
