Appropriate-temperature and appropriate-humidity environment control system based on human body thermal comfort mechanism

Abstract

The invention discloses an appropriate-temperature and appropriate-humidity environment control system based on a human body thermal comfort mechanism. The appropriate-temperature and appropriate-humidity environment control system comprises an intelligent environment control gateway and an indoor environment sensor, an outdoor meteorological parameter acquisition system, a multi-split air conditioner unit, a fresh air unit and an information acquisition device which are connected with the intelligent environment control gateway. According to the appropriate-temperature and appropriate-humidity environment control system based on the human body thermal comfort mechanism, a dynamic indoor thermal environment has the obvious benefits on the health and the comfortableness of a user, an air conditioning system adopting intelligent learning is more humanized, the user experience can be better improved, and the user requirements are met.

Description

technical field [0001] The invention relates to the technical field of thermal comfort control, in particular to an environment control system based on the thermal comfort mechanism of the human body. Background technique [0002] With the development of the economy, people pursue the improvement of living standards, and the requirements for the comfort of the indoor environment are getting higher and higher. However, there is still some controversy over the definition of comfort in the academic circles at this stage. The most familiar definition is that "thermal neutrality" without stimulation and without self-regulation is equal to "comfort". With the development of thermal comfort theory, another The point of view is produced, and its comfort is a kind of short-term pleasure, which is accompanied by the elimination of discomfort, and only a dynamic environment can bring comfort and health. These two opposing views of comfort correspond to completely different ways of cre...

Problems solved by technology

As mentioned above, the specifications for indoor thermal environment parameters in the specification are based on the PMV model, and PMV represents the average temperature sensation of most people in a certain environment. However, for individual users in a residence, clothing conditions and metabolic rate intensity, both of which have a significant impact on the human body's cold and hot feelings, have relatively large degrees of freedom and uncertainty, and it is difficult to make accurate predictions based on the type of room

On the other hand, the PMV thermal comfort evaluation method does not take into account individual differences between people. Simply put, as long as the six parameters in the PMIV model are the same, people will have the same feeling of heat and cold.

However, in fact, physiological differences such as gender, age, and body fat content will affect the human body's hot and cold sensation to a certain extent. Therefore, copying the settings of thermal environment parameters in the specification cannot meet the individual needs of users.
