Abstract

The invention discloses a device for automatically realizing fresh air replacement for an integral external air conditioner. The device comprises a square cabin and the integral external air conditioner, wherein a carbon dioxide sensor is arranged at an air return opening of the integral external air conditioner; a ventilation air valve assembly is arranged in an evaporation air cavity of the integral external air conditioner; an air inlet of the ventilation air valve assembly is led to an external environment, and the ventilation air valve assembly comprises an air valve mechanism and a driving mechanism for driving the air valve mechanism to work; the carbon dioxide sensor and the driving mechanism are electrically connected with a control panel of the integral external air conditioner respectively through signal cables. By detection of the concentration of carbon dioxide in the square cabin or a room, fresh air replacement is automatically and intelligently realized, so that fresh air can be automatically supplemented into the square cabin; therefore, potential safety hazards caused by extremely high concentration of the carbon dioxide in the closed square cabin where a worker stays for a long time are avoided.

Description

technical field

[0001] The invention relates to the field of external air conditioners, in particular to a device that automatically activates the ventilation function by monitoring the carbon dioxide concentration in the cabin or indoors, and uses negative pressure ventilation to automatically realize the fresh air exchange of the overall external air conditioner. Background technique

[0002] At present, the overall external air conditioner is mostly used for air conditioning in the military shelter to ensure that the electronic equipment and operators in the military shelter provide a good working environment and ensure that the system is in good working condition.

[0003] Generally, due to the special requirements of military shelters, the shelters are well airtight, and fresh air needs to be replenished into the cabins regularly. Existing integral external air conditioners that require fresh air replacement are generally used for manual fresh air replacement when they a...
