AI Technical Summary
In existing air conditioners, the humidifier is usually placed after the fan when adjusting temperature and humidity. This results in an increased structural size and the potential for condensation leakage. In particular, in the humid marine environment, the steam ejection speed affects the air supply, increasing safety hazards.
A compact variable air volume (VAV) air conditioner is designed. By installing a temperature and humidity sensor and an electrically adjustable air valve in the mixing air intake cavity, combined with the buffer tank and steam regulating valve of the humidifier, humidification is ensured after steam buffering, and condensate is discharged from the water collection tray to avoid direct spraying. A frame structure and a detachable panel are adopted to meet the requirements of compact space.
It achieves efficient humidification and control of air supply temperature and humidity while improving equipment safety, preventing condensation leakage, and meeting the requirements for space size and ease of maintenance.
