Inverter air conditioner frequency control method, control device and inverter air conditioner

Abstract

The invention discloses a frequency control method and device for an inverter air conditioner and the inverter air conditioner. The frequency control method comprises the steps that the air conditioner operates in a refrigerating mode, and room temperature PID computation is conducted according to a temperature difference between a real-time indoor ambient temperature and a set target temperature to obtain first frequency; a heat source in a room where the air conditioner is located is detected, a real-time distance between the heat source and the air conditioner is determined, and frequency corresponding to the real-time distance is determined and serves as second frequency; coil pipe temperature PID computation is conducted according to a temperature difference between a real-time coil pipe temperature and a set pipe target temperature to obtain third frequency; if the real-time indoor ambient temperature is not smaller than a set comfortable temperature, the smaller one of the first frequency and the second frequency is selected as the target frequency; if the real-time indoor ambient temperature is smaller than the set comfortable temperature, the smallest one of the first frequency, the second frequency and the third frequency is selected as the target frequency; and a compressor of the air conditioner is controlled to operate according to the target frequency. Application of the frequency control method and device for the inverter air conditioner and the inverter air conditioner can achieve energy-saving and comfortable control for the air conditioner.

Description

Technical field [0001] The present invention belongs to the technical field of air conditioning. Specifically, it relates to air conditioning equipment that regulates indoor air, and more specifically, it relates to a frequency control method based on an inverter air conditioner, a control device, and an inverter air conditioner. Background technique [0002] The air conditioner can be used for cooling in summer and heating in winter, and can adjust the indoor temperature to warm in winter and cool in summer, providing users with a comfortable environment. While air conditioning provides users with comfort, it is accompanied by contradictions with high energy consumption. Energy consumption not only increases the economic burden of users, but also runs counter to the trend of energy conservation and environmental protection. Therefore, how to use air conditioners to provide users with a comfortable environment while reducing the energy consumption of air conditioners is a proble...
