Method and device for achieving refrigeration control of air conditioner

Abstract

The invention discloses a method and device for achieving refrigeration control of an air conditioner. The method comprises the steps that the air conditioner operates in a refrigeration manner, room temperature PID operation is carried out according to the temperature difference of the real-time indoor environment temperature and the set indoor target temperature, and the first frequency is obtained; the real-time distance between a target in a room where in the air conditioner is located and the air conditioner is acquired, the real-time air speed corresponding to the real-time distance and the frequency corresponding to the real-time air speed are determined, and the frequency serves as the second frequency; coil temperature PID operation is carried out according to the temperature difference of the real-time coil temperature and the set coil target temperature, and the third frequency is obtained; if the real-time indoor environment temperature is not smaller than the set comfortable temperature, the smaller value in the first frequency and the second frequency is selected as the target frequency; if the real-time indoor environment temperature is smaller than the set comfortable temperature, the smaller value in the first frequency, the second frequency and the third frequency is selected as the target frequency; and operation of a compressor of the air conditioner is controlled according to the target frequency. By means of the method and device, energy-saving and comfortable control of the air conditioner can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, specifically relates to an air conditioner for adjusting indoor air, and more specifically relates to a method and device for realizing air conditioning refrigeration control. 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 manufacturers have been working hard to s...

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
