Abstract
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...
