Abstract

The invention discloses an automatic adjustment method and system for wind power balance of a central air conditioning system. The system comprises multiple levels of pipeline mechanisms, wherein eachpipeline in each level of pipeline mechanism is connected with a plurality of lower-level pipelines connected in parallel. According to the adjustment method, through grading adjustment, the air volume ratio of each pipeline is adjusted to meet a requirement, and the tedious steps of traditional manual wind power balance adjustment are reduced; meanwhile, manual expenditure for adjusting the windpower balance of an air conditioner is saved for an owner; and besides, the problem of wind power imbalance of an air conditioning wind system is solved, the problem of complaining of tenants (customers) caused by non-uniform heat and cold at the tail end of the air conditioner is solved, and a key effect is achieved on saving energy during operation of the air conditioner for the owner. According to the adjustment system, the air volume ratio of each pipelines is calculated through an air volume meter on the corresponding pipeline and is transmitted to a central controller, and the central controller performs processing and analysis to control an adjusting valve of each pipeline to adjust the air volume of the corresponding pipeline, so that the air volume ratios of the pipelines meet the requirements, and then the wind power of the central air conditioning wind system is balanced.

Description

technical field

[0001] The invention relates to the field of air conditioning adjustment, in particular to an automatic adjustment method and system for wind force balance of a centralized air conditioning system. Background technique

[0002] At present, centralized air-conditioning systems have been widely used in various public buildings, but after operation, the air force of the centralized air-conditioning system is often unbalanced, and the actual air volume of each pipeline is quite different from the designed air volume, resulting in uneven cooling and heating of the air-conditioning terminals on the same floor. The phenomenon of large temperature gradients on different floors.

[0003] Especially in the public areas of some commercial buildings, the central air-conditioning system used in them only did a trial run of the air-conditioning system when the project was completed, and most of them did not adjust the wind balance of the air-conditioning system during the ...
