Problems solved by technology

The PMV index represents the feeling of most people in the same environment, so it can be used to evaluate whether a thermal environment is comfortable or not, but there are individual differences between people, so the PMV index may not represent the feeling of all individuals
In the PMV equation, the human body metabolic rate is difficult to monitor dynamically, so the existing intelligent air conditioning control system usually adopts a default value of about 1.2met, but this may be quite different from the actual situation of the indoor personnel, so it is difficult for users to requirements for comfort

Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] Such as figure 1 As shown, the present invention discloses a method for controlling indoor thermal environment based on heart rate monitoring, including:

[0042] S1. Collection of indoor air temperature t a and indoor humidity RH;

[0043] In the present invention, the temperature and humidity information in the room can be collected through the temperature sensor and the humidity sensor installed in the room.

[0044] S2, based on the collected indoor air temperature t a and the indoor humidity RH to calculate the indoor air moisture partial pressure Pa;

[0045] Indoor air moisture partial pressure Pa can be calculated according to the following formula:

[0046] Pa=RH*10*Exp(16.6536-4030.183 / (t a +235))

[0047] S3. Collect the user's average historical sleep heart rate as the resting heart rate HR o , collect the heart rate of the user for...

Abstract

The invention discloses an indoor thermal environment regulation and control method based on heart rate monitoring. The indoor thermal environment regulation and control method comprises the steps that indoor air moisture partial pressure Pa is calculated based on collected indoor air temperature T and indoor humidity RH; a user real-time metabolic rate estimated value M is calculated based onresting heart rate HR<o> and real-time average heart rate HR; a user thermal sensation index CPMV<0> is calculated based on the indoor air temperature T, the indoor air moisture partial pressure Paand the user real-time metabolic rate estimated value M; and an air conditioner is controlled based on the user thermal sensation index CPMV<0>. The air conditioner can be more effectively operated,regulated and controlled, and a great effect is achieved for creating a dynamic indoor thermal environment conforming to natural health. Compared with a traditional control model, the thermal sensation prediction value is more accurate, and the comfort degree of the indoor thermal environment created according to the regulation and control method is greatly improved.

Description

technical field [0001] The invention relates to the field of temperature regulation, in particular to an indoor thermal environment regulation method based on heart rate monitoring. Background technique [0002] Air-conditioning system energy consumption accounts for more than 30% of building energy consumption. Reasonable air-conditioning control methods play an important role in human comfort and building energy conservation. [0003] In the prior art, the intelligent air-conditioning control system usually adjusts the indoor temperature according to the PMV equation and the like. PMV (Predicted Mean Vote) is a comprehensive evaluation index based on the basic equation of human body heat balance and the level of subjective thermal sensation in psychophysiology, taking into account many factors related to human thermal comfort. The PMV index represents the feeling of most people in the same environment, so it can be used to evaluate whether a thermal environment is comfort...
