Embodiment Construction

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail with reference to the accompanying drawings and embodiments.

[0030] See figure 1 This figure shows a flowchart of an embodiment of a method for implementing air conditioning and refrigeration control based on distance in the present invention.

[0031] Such as figure 1 As shown, the method for realizing air-conditioning refrigeration control based on distance in this embodiment adopts a process with the following steps:

[0032] Step 11: Air conditioner cooling operation, obtain real-time indoor ambient temperature, set indoor target temperature, at the same time, detect the heat source in the room where the air conditioner is located in real time and determine the real-time distance between the heat source and the air conditioner.

[0033] Specifically, when the air conditioner is turned on and running, the i...

Abstract

The invention discloses a method and device for achieving refrigeration control of an air conditioner based on a distance. The method comprises the steps that the air conditioner performs refrigeration operation and performs room temperature PID operation to obtain first frequency; a real-time distance between an indoor heat source and the air conditioner is determined, 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 second frequency; according to the difference of real-time coil temperature and target coil temperature, coil temperature PID operation is performed to obtain third frequency; the target coil temperature is determined according to the indoor target temperature, and it is achieved that the target coil temperature is low when the indoor target temperature is low; if the indoor target temperature is not lower than set suitable temperature, a smaller value in the first frequency and the second frequency is selected as target frequency; if the temperature is lower than the set suitable temperature, a smaller value in the first frequency, the second frequency and the third frequency is selected as target frequency. By applying the method and the device, energy saving and comfort control of the air conditioner can be achieved.

Description

Technical field [0001] The present invention belongs to the field of air conditioning technology. Specifically, it relates to an air conditioner that regulates indoor air, and more specifically, it relates to a method and device for realizing air conditioning refrigeration control based on distance. 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 problem that air conditioner manufac...
