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] like 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, the ...

Abstract

The invention discloses a control method and a control device for the frequency of a variable frequency air conditioner. The method comprises the following steps: operating the air conditioner for refrigerating, and carrying out room temperature PID calculation according to temperature difference between indoor environment temperature and set target temperature, so as to obtain a first frequency; detecting a heat source in a room where the air conditioner is arranged and determining the real-time distance between the heat source and the air conditioner, and determining the frequency corresponding to the real-time distance to be used as a second frequency; if the real-time distance is not smaller than set distance, selecting a relatively small value in the first frequency and the second frequency as a target frequency; if the real-time distance is smaller than the set distance, determining the target frequency according to real-time coiled pipe temperature and real-time coiled pipe target temperature; and controlling the operation of a compressor of the air conditioner according to the target frequency. By applying the control method and the control device, energy-saving and comfortable control on 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...
