Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] See figure 1 , which is a flow chart of an embodiment of the frequency control method of the inverter air conditioner of the present invention.

[0028] Such as figure 1 As shown, the method for realizing the frequency control of the inverter air conditioner in this embodiment is realized by a process with the following steps:

[0029] Step 11: The air conditioner operates in cooling mode, obtains the real-time indoor ambient temperature, sets the indoor target temperature, and at the same time, detects the heat source in the room where the air conditioner is located in real time and determines the real-time distance between the heat source and the air conditioner.

[0030] Specifically, when the air conditioner is turned on and running, t...

Abstract

The invention discloses a variable frequency air conditioner frequency control method and device. The variable frequency air conditioner frequency 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 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, and a frequency corresponding to the real-time distance is determined to serve as a second frequency; 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, a target frequency is selected according to fuzzy control based on the real-time coil temperature; and a compressor of the air conditioner is controlled to operate according to the target frequency. By means of the variable frequency air conditioner frequency control method and device, 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, in particular relates to an air conditioner for adjusting indoor air, and more specifically relates to a frequency control method and a control device for an inverter air conditioner. 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 h...
