Embodiment Construction

[0054] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0055] The invention proposes a method for controlling the comfort of an air conditioner, which controls the air conditioner by taking the comfort index as the control target. Such as figure 1 As shown, the comfort index is an evaluation index that characterizes the human body's thermal response (hot and cold sensation) proposed by Professor P.O.Fanger of Denmark, including six parameters: air temperature, air humidity, wind speed, radiation temperature, clothing Thermal resistance and human metabolic rate. After a lot of data research and testing of different objects, Fanger came up with a comfort equation. After obtaining the six parameters, the corresponding com...

Abstract

The invention discloses a comfort control method of an air conditioner. The method comprises the steps that when it is detected that the comfort control of the air conditioner is started, a target comfort level is obtained; the indoor environment temperature, the dress heat resistance, the human body metabolic rate and the radiation temperature are obtained; the target comfort level, the indoor environment temperature, the dress heat resistance, the human body metabolic rate and the radiation temperature are substituted into a preset comfort level formula, and a comfort curve with wind speed and humidity associated is obtained; and according to the comfort curve with wind speed and humidity associated, the air conditioner is controlled to run. The invention further discloses a comfort control device of the air conditioner. By means of the embodiment, the temperature of a room can reach and be stabilized in the most comfortable human sensation state. According to the method and the device, the temperature of the air conditioner can be stabilized within the comfort range, and the energy-saving effect of the air conditioner is achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner comfort control method and device. Background technique [0002] There are many factors affecting the thermal comfort of the human body, and the comprehensive comfort index—PMV index proposed by Professor P.O.Fanger in Denmark has received extensive attention for its comprehensiveness. The PMV metric takes into account six parameters that affect comfort: the effects of room temperature, humidity, radiant temperature, clothing thermal resistance, metabolic rate, and wind speed. Comprehensive control of comfort can be realized by comprehensively analyzing the influence degree of each parameter on human thermal comfort. [0003] However, current air conditioners only involve temperature and / or humidity control, without considering whether the currently controlled indoor environment meets comfort conditions. Contents of the invention [0004] The main purpose of...
