Method, device and air conditioner for realizing energy saving control of air conditioner based on distance

Abstract

The invention discloses an air conditioner energy saving control method and device based on distance and an air conditioner. The air conditioner energy saving control method comprises the steps that when the air conditioner operates, the real-time indoor environment temperature and the set target temperature are obtained, the temperature difference between the real-time indoor environment temperature and the set target temperature is calculated to serve as the real-time temperature difference, room temperature PID operation is conducted according to the real-time temperature difference, and a first frequency is obtained; a heat source of a room where the air conditioner is located is detected in real time, the real-time distance between the heat source and the air conditioner is determined, the air speed corresponding to the real-time distance is determined according to the known corresponding relationship between the distance and the air speed to serve as the real-time air speed, and a frequency corresponding to the real-time air speed is obtained according to the known corresponding relationship between the air speed and the frequency to serve as a second frequency; and the smaller one of the first frequency and the second frequency is selected as a target frequency, and a compressor of the air conditioner is controlled to operate according to the target frequency. By means of the air conditioner energy saving control method and device based on the distance and the air conditioner, energy saving control over the air conditioner can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air conditioner for adjusting indoor air, and more specifically relates to a method and device for realizing energy-saving control of an air conditioner based on a distance, and an air conditioner. Background technique [0002] The air conditioner can cool in summer and heat in winter, and can adjust the indoor temperature to make it warm in winter and cool in summer, providing users with a comfortable environment. While air conditioners provide users with comfort, it is accompanied by contradictions with high energy consumption. Energy consumption not only increases the economic burden of users, but also goes against the trend of energy conservation and environmental protection. Therefore, how to reduce the energy consumption of the air conditioner while using the air conditioner to provide a comfortable environment for the user is a problem that the air...

Problems solved by technology

However, the control method of simply controlling the operating frequency of the compressor based on temperature cannot achieve better energy-saving control, especially in the case of running at the same temperature and different wind speeds, it is difficult to achieve ideal energy-saving control
