Description

Garage Intelligent Ventilation Smoke Exhaust Dehumidification System and Its Control Method

technical field

The invention relates to the field of building control equipment, in particular to an intelligent ventilation, smoke exhaust and dehumidification system for a garage and a control method thereof.

Background technique

With the improvement of people's living standards, more and more families start to own private cars. In order to meet the needs of parking, many urban buildings are equipped with underground garages. Due to the limitations of its own structure, the underground garage cannot be equipped with windows for ventilation, but relies on a mechanical air supply and exhaust system. At present, the air supply and exhaust systems commonly used in underground garages are generally the following two types: conventional air supply and exhaust systems and jet induced ventilation systems. In terms of control methods, manual control of the induced ventilation system is mostly adopted. Manual control is adopted. The garage managers use personal experience to realize switch control of the induction fan system and the main exhaust fan. Manual control has defects in energy saving and practical effects. In addition, when a fire breaks out, due to the large area of the garage and its relatively empty space, the smoke generated will not be able to spread quickly, and the smoke generated in one place will put the entire garage in danger, and all the exhaust systems in the garage need to be activated to remove the smoke. Low, high cost.
