Air conditioning control method and system

Abstract

An air-conditioning control method, comprising the following steps: S1: training a user's historical physiological parameters, indoor environment parameters, personal parameters and subjective evaluation results of thermal comfort, to obtain a human body thermal comfort model of the user; S2: obtaining the user The above-mentioned parameters at the current moment are input into the human thermal comfort model, a PMV output value is obtained, and an operation command is output according to the displayed PMV output value; S3: Send the operation command to the air conditioner to change the operation of the air conditioner state; S4: after a period of time, continue to perform step S2 until the PMV output value is within the preset PMV threshold range; the present invention also provides an air-conditioning control system utilizing the method. The air conditioning control method and system disclosed in the present invention are based on the thermal comfort of the human body, and according to the current thermal comfort of the user, the most suitable air conditioning adjustment mode for the user is made, the intelligent automatic adjustment of the air conditioning system is completed, and the realization of Dynamic thermal comfort control of indoor environments.

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
