Novel air volume optimization method and unit pricing method

Abstract

The invention provides a novel air volume optimization method and a unit pricing method. The new air volume optimization method comprises the following steps that 1, the current concentration of any one of pollutants is acquired on the basis of a detection unit of any one of the pollutants; 2, the current fresh air volume of an air conditioning system is acquired; 3, the optimal fresh air volume corresponding to any one of the pollutants is acquired on the basis of the current concentration of any one of the pollutants and the current fresh air amount; and 4, the maximum value of the optimal fresh air amount is selected as the optimal fresh air amount from the optimized fresh air volume corresponding to each pollutant. According to the method, the current concentration of each pollutant and the current fresh air volume are calculated, and the optimal fresh air quantity is obtained so as to realize the fresh air volume adjustment of the air conditioning system; and on the premise of ensuring the indoor air quality, energy waste and equipment loss caused by blind improvement of new air volume are avoided, energy is saved, the requirements of a fan are reduced, the service life of consumable materials such as a filter is prolonged, and the operation and maintenance cost of the air conditioning system is reduced.

Description

technical field [0001] The invention relates to the technical field of indoor ventilation control, in particular to a fresh air volume optimization method and a unit pricing method. Background technique [0002] With the advancement of industrialization and the improvement of people's living standards, environmental issues, especially air quality issues, have increasingly attracted people's attention. For indoor air quality, such as the concentration of carbon dioxide, formaldehyde and other volatile organic compounds, and the content of fine particulate matter PM2.5 It is of great significance to control it. [0003] The current air conditioning system mostly adopts the mode of partial fresh air and partial return air to realize indoor temperature and indoor air quality control. Among them, the fresh air is the air directly introduced from the outside, and the return air is the air originally existing in the room. The return air circulation will cause the continuous accum...
