A method and device for realizing air-conditioning refrigeration control based on distance

Abstract

The invention discloses a distance-based method and device for achieving refrigeration control over an air conditioner. The method comprises the steps that room temperature PID computation is conducted according to a temperature difference between a real-time indoor ambient temperature and a set indoor target temperature to obtain first frequency; a real-time distance between an indoor heat source and the air conditioner is determined, a real-time wind speed corresponding to the real-time distance is determined and then frequency corresponding to the real-time wind speed is determined and serves as second frequency; a real-time coil pipe target temperature corresponding to the real-time distance is determined, and coil pipe temperature PID computation is conducted according to a temperature difference between a real-time coil pipe temperature and the real-time coil pipe target temperature to obtain third frequency; if the real-time distance is not smaller than a set distance, the smaller one of the first frequency and the second frequency is selected as the target frequency; if the real-time distance is smaller than the set distance, 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 distance-based method and device for achieving refrigeration control for the air conditioner can achieve the energy-saving and comfortable refrigeration control over the air conditioner.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to an air conditioner for adjusting indoor air, and more specifically relates to a method and device for realizing air conditioning 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 manufacturers have bee...

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
