Air conditioner refrigeration control method and device based on distance

Abstract

The invention discloses an air conditioner refrigeration control method and device based on distance. The air conditioner refrigeration control method comprises the steps that air conditioner refrigeration operation is conducted, specifically, room temperature PID operation is conducted according to the temperature difference between the real-time indoor environment temperature and the set indoor target temperature, and a first frequency is obtained; a heat source of a room where an air conditioner is located is detected, the real-time distance between the heat source and the air conditioner is determined, the real-time air speed corresponding to the real-time distance is determined, and a frequency corresponding to the real-time air speed is determined to serve as a second frequency; coil temperature PID operation is conducted according to the temperature difference between the real-time coil temperature and the set coil target temperature, and a third frequency is obtained; if the real-time indoor environment temperature is not lower than the set comfortable temperature, the smaller one of the first frequency and the second frequency is selected as a target frequency; if the real-time indoor environment temperature is lower than the set comfortable temperature, the smallest of the first frequency, the second frequency and the third 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 refrigeration control method and device based on the distance, energy saving and comfortable 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 air conditioning equipment for adjusting indoor air, and more specifically relates to a method and device for realizing air conditioning and refrigeration control based on distance. 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 conditioner manufa...

Problems solved by technology

However, the control method of simply controlling the operating frequency of the compressor based on the 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 and comfortable control
