Abstract: The multi-temperature control cabinet includes a cabinet body, a cabinet door, and a refrigerating system. The refrigerating system includes at least one air conditioner, at least one direct ventilation unit, and an environment monitoring apparatus. Both the air conditioner and the direct ventilation unit are disposed on the cabinet door, and the air conditioner and the direct ventilation unit are disposed in parallel in a height direction of the cabinet door. An air guide assembly is disposed between the direct ventilation unit and an air exhaust vent of the air conditioner. The environment monitoring apparatus is connected to both the air conditioner and the direct ventilation unit, and the environment monitoring apparatus is configured to monitor temperature and humidity in the cabinet body, and control turning-on and turning-off of the air conditioner and the direct ventilation unit based on the temperature and the humidity in the cabinet body.
