Air conditioner control method and system

Abstract

An air conditioner control method includes the following steps that firstly, historic physiological parameters of a user, indoor environment parameters, personal parameters and a thermal comfort degree subjective assessment result are trained and a human body thermal comfort degree model of the user is acquired; secondly, all the parameters of the user at the current moment are acquired and input into the human body thermal comfort degree model, a PMV output value is acquired, and according to the PMV output value, an operation command is output; thirdly, the operation command is sent to an air conditioner to change the operation state of the air conditioner; fourthly, after a period of time, the second step is conducted continuously till the PMV output value is within a preset PMV threshold value range. The invention further provides an air conditioner control system using the method. By the adoption of the air conditioner control method and system, the human body thermal comfort degree serves as a starting point, an air conditioner adjusting mode suitable for the user is adopted according to the thermal comfort condition of the current user, an air conditioner system is intelligently and automatically adjusted, and dynamic thermal comfort control of the indoor environment is achieved.

Description

technical field [0001] The invention relates to the field of air conditioning control, in particular to an air conditioning adjustment method and system based on human physiological parameters and indoor environment. Background technique [0002] Nowadays, air-conditioning has become an indispensable part of improving the heat and humidity conditions of the indoor environment. By adjusting the set values ​​of temperature, humidity and wind speed, the adjustment and control of indoor environmental parameters can be realized, thereby changing the thermal comfort of the human body. [0003] With regard to the control of the air conditioning system, the user usually changes the heat and humidity conditions of the indoor environment by adjusting the temperature and humidity and the set value of the wind speed. This has the following problems: 1) The setting value of the air conditioning system is often carried out manually, and the system cannot automatically adjust the setting v...

Problems solved by technology

This has the following problems: 1) The setting value of the air conditioning system is often carried out manually, and the system cannot automatically adjust the setting value according to the comfortable state of the human body; 2) The temperature value, humidity value and wind speed value set by the user It is not necessarily required in a thermal comfort environment, and often requires the user to manually adjust it many times, which brings a lot of inconvenience to the user; 3) Blind manual setting, the user cannot find an optimal combination of environmental parameters in a short time

The patent with publication number CN 104061663 A proposes an air-conditioning control method and device, which calculates the human body’s sensory temperature by measuring the ambient temperature and humidity to evaluate the environment and make control decisions. However, the sensory temperature obtained in this invention is calculated It is not obtained by direct measurement, and the accuracy and effectiveness are worthy of attention; the patent with the publication number of CN 103062871A proposes an air-conditioning control system based on skin temperature, but in this invention, the human skin temperature is simply used as the evaluation The index of thermal comfort is too unconvincing. In addition, when adjusting, it only adjusts the temperature, and does not give the optimal combination of parameters; the patent with the publication number of CN 103398451A proposes a method based on learning user behavior The multi-dimensional comfort indoor environment control method and system, but the influence of physiological parameters is not considered in the control process
