Problems solved by technology

[0004] However, the existing fan devices used in conjunction with air-conditioning equipment can usually only be adjusted through artificial passive methods, which is prone to overcooling or overheating of the indoor environment, which not only consumes power and wastes energy, The overcooling or overheating caused by the device will also cause discomfort to the occupants of the room

Embodiment Construction

[0027] The novelty and other features of the present invention will become clearer with the detailed description of the embodiments of the accompanying drawings below.

[0028] The thermal comfort of the human body is mainly affected by six parameters such as temperature, wind speed, air humidity, average radiant temperature, human activity, and clothing. Through these parameters, comfort quantitative evaluation can be carried out to obtain the so-called predicted average comfort. The indicator (Predicted Mean Value, PMV) usually divides the PMV human comfort index from extremely cold -3 to extremely hot +3, and 0 represents moderate thermal sensation. The general PMV can be obtained by the following formula:

[0029] PMV = [ 0.303 exp ( - 0.036 M ) + 0.028 ] × ...

Abstract

Provided are a control system and method for an intelligent energy-saving fan. The method mainly comprises the steps of reserving a PMV area in indoor space already provided with air conditioning equipment and a fan in advance, and measuring and obtaining an indoor environment PMV value; carrying out range comparison judgment on the set PMV area and the indoor environment PMV value; driving the fan to automatically increase the rotating speed when it is judged that the indoor environment PMV value is larger than the set PMV area, and automatically reducing the rotating speed of the fan when it is judged that the indoor environment PMV value is smaller than the set PMV area; therefore, the indoor living environment can be automatically controlled and maintained in the optimal human body comfort degree, and the energy consumption phenomenon, of excessive heat and cold, caused by existing equipment can be effectively improved.

Description

technical field [0001] The present invention relates to an intelligent energy-saving fan control system and method. After comparing and controlling the set predicted average comfort index (PMV) with the indoor environment where air conditioners and fans are installed at the same time, the fan can be automatically rotated. Adjust to achieve a better indoor environment comfort, and effectively achieve the purpose of energy saving. Background technique [0002] The basic function of air-conditioning equipment is mainly to provide users with a comfortable living environment. Whether it is to provide low-temperature cold air in a high-temperature indoor environment or to provide heating in a low-temperature environment, most of today’s air-conditioning equipment can achieve the function of indoor high and low temperature adjustment. , but due to the continuous improvement of energy prices, the energy consumed by air-conditioning equipment will form a considerable burden on users....
