Abstract
Description
technical field
[0001] The invention relates to a fresh air energy-saving control technology, in particular to a fresh air system based on video people flow statistics and an energy-saving control method thereof. Background technique
[0002] As early as the beginning of the 20th century, people have begun to use ventilation to improve the indoor air environment. Later, the emergence of refrigeration and air-conditioning systems created a comfortable air-conditioning environment for people. However, the global energy crisis in the 1970s made the refrigeration and air-conditioning system, a large energy consumer, face severe challenges. Energy saving and consumption reduction have become the key link in the design of air-conditioning systems. On the one hand, people improve the airtightness and thermal insulation of buildings, and at the same time reduce the minimum indoor fresh air volume standard, resulting in an increase in the concentration of indoor harmful pollutants du...
