A HVAC system control method based on multi-user thermal comfort data

Abstract

The invention provides a heating and ventilating system control method based on multiple-user thermal comfort data. The method comprises the steps that user thermal comfort data are obtained according to current season information fed back by users, the current user movement states and thermal comfort preference; corresponding user thermal comfort preference curves are obtained according to the user thermal comfort data; the thermal comfort probability distribution curves of cold, hot and comfort are obtained according to the user thermal comfort preference curves; a multiple-user thermal comfort probability distribution curve at different indoor environment temperature is obtained according to the thermal comfort probability distribution curves of all users; and the comfort temperature interval of the multiple-user thermal comfort probability distribution curve is used as a selection interval of temperature set values, and the optimal temperature set value of a controlled thermal space is obtained according to the corresponding relation of the air supply volume and the temperature set value. Through the method, the comfort of indoor persons is effectively improved, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to the technical field of intelligent optimization of HVAC energy consumption, and specifically relates to a HVAC system control method based on multi-user thermal comfort data. Background technique [0002] Heating, ventilation and air-conditioning system (HVAC) is almost an indispensable household and commercial appliance in contemporary society. Today, people pay more and more attention to their own quality of life and quality, and it is important for our comfort, health, satisfaction and The HVAC system, which has a great impact on work efficiency and other aspects, has almost been fully integrated into our lives all the time. It is precisely because of its indispensability that the US Department of Energy survey found that the energy consumption of the HVAC system accounts for 40% to 60% of the energy consumption of the entire building. [0003] At the same time, d...
