Embodiment Construction

[0028] 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.

[0029] 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.

[0030] 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:

[0031] 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 obtains the real-time distance between the target in the room where the air conditioner is located and the air conditioner.

[0032] Specifically, when the air conditioner is turned on and running, the indoor ambient temperature of the room where th...

Abstract

The invention discloses a frequency control method and device for a variable-frequency air conditioner. The frequency control method for the variable-frequency air conditioner comprises the steps that the air conditioner operates in a refrigerating mode, and indoor temperature PID operation is conducted, so that a first frequency is obtained; the real-time distance between a target in the room where the air conditioner is located and the air conditioner is obtained, and the frequency corresponding to the real-time distance is determined and used as a second frequency; coil pipe temperature PID operation is conducted according to the difference between the real-time coil pipe temperature and a coil pipe target temperature, so that a third frequency is obtained, the coil pipe target temperature is determined according to the indoor target temperature, and when the indoor target temperature is low, the coil pipe target temperature is also low; if the real-time indoor environment temperature is not lower than a set comfortable temperature, the smaller one of the first frequency and the second frequency is used as the target frequency; and if the real-time indoor environment temperature is lower than the set comfortable temperature, the smaller one of the first frequency, the second frequency and the third frequency is used as the target frequency. By applying the frequency control method and device for the variable-frequency air conditioner, control over energy saving and comfort of the air conditioner can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and 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 air conditioner based on frequency conversion. 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 manufa...
