Problems solved by technology

However, the conventional method in the prior art is that the host (fan) of the fresh air device directly operates to supply the needs of each room. In this way, the host cannot be effectively allocated and adjusted according to the needs of each room. At the same time, the resistance of the air duct network needs to be overcome, and the operating efficiency is low.

Abstract

The invention discloses a central ventilation system capable of being adjusted as required, and an air volume control method thereof. The air volume control method of the central ventilation system comprises the steps of arranging multiple air pipe pressurization units in an air pipe of the central ventilation system at intervals; detecting the air volume demand of each room, calculating the totalair volume demand according to the air volume demand of each room, and controlling the frequency of a fan of the central ventilation system according to the total air volume demand; and detecting theactual air volume of each room, and controlling the relevant air pipe pressurization unit of the room to sequentially open or close according to the relationship between the actual air volume of eachroom and the air volume demand of each room. According to the central ventilation system capable of being adjusted as required provided by the invention, the air volume of each area can be adjusted as required so as to be distributed as required.

Description

technical field [0001] The invention relates to a central ventilation system and an air volume control method of the central ventilation system. Background technique [0002] With the popularity of high-rise buildings and large buildings, fresh air devices (that is, ventilation devices) are currently widely used in civil comfort occasions such as green buildings, transportation hubs, education and medical care. However, for complex buildings, on the basis of ensuring economy, it is necessary to control the ventilation circuit more reasonably, reasonably distribute the ventilation demand, and make the engineering load operate at the best point in order to optimize the energy efficiency of the unit. This is what the fresh air HVAC project needs to face and solve. one question. However, the conventional method in the prior art is that the host (fan) of the fresh air device directly operates to supply the needs of each room. In this way, the host cannot be effectively allocated...
