Research on Calculation Method and Application of MPV Index in Underground
At present,the air conditioning system of underground engineering is not able to accurately meet the needs of personnel for thermal comfort.In this paper,PMV index is introduced as the evaluation standard of thermal comfort of underground engineering,and the calculation method of PMV index considering the influence of personnel activities,clothing,mountain temperature,air supply of air conditioning and other factors is studied.By using Maple software,this paper analyzes the different temperature and humidity combination intervals under the same comfort and the influence of temperature and humidity on PMV value.The intelligent control method of air conditioning based on PMV index is proposed,and the automatic correction flow of temperature and humidity setting value is given.
