Embodiment Construction

[0024] 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.

[0025] See figure 1 , which is a flow chart of an embodiment of the method for controlling the heating operation of the air conditioner according to the present invention.

[0026] Such as figure 1 As shown, the specific process of realizing heating control in this embodiment is as follows:

[0027] Step 11: The air conditioner operates in heating mode, acquires the indoor temperature, and compares the indoor temperature with the first indoor temperature threshold.

[0028] Specifically, the indoor temperature refers to the indoor temperature of the room where the air conditioner is located, which is acquired in real time according to a set frequency when the air conditioner is turned on and running in a heating mode. Acquisition of the indoor t...

Abstract

The invention discloses a heating operation control method and a control device of an air conditioner. The method comprises the steps that when the air conditioner carries out heating operation, the indoor temperature is acquired; if the indoor temperature is not larger than a first indoor temperature threshold value, fuzzy control is executed; according to the temperature difference between the indoor temperature and the set indoor target temperature, indoor temperature PID operation is carried out, and a first target frequency is acquired; the coil pipe temperature of an indoor heat exchanger is acquired, and if the coil pipe temperature is larger than a coil pipe target temperature, the first target frequency is determined as an indoor unit frequency; or otherwise, the current operation frequency of a compressor is increased to acquire a second target frequency, the larger value in the first target frequency and the second target frequency is selected as an indoor unit frequency; according to the indoor unit frequency, the compressor of the air conditioner is controlled; and while double PID control is executed, electric heating is controlled according to the coil pipe temperature. By applying the heating operation control method and the control device, the problem that an existing air conditioner is slow in heating and consequently people feel uncomfortable during heating can be solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to the control of an air conditioner, and more specifically relates to a method and a control device for controlling the heating operation of the air conditioner. Background technique [0002] In the cold winter, air conditioners are the main way of heating in areas without heating conditions or in cold weather where heating is stopped. [0003] During the heating operation of the existing air conditioners, the frequency of the compressor is controlled according to the difference between the indoor temperature and the set indoor target temperature. If the frequency of the compressor obtained according to the difference between the indoor temperature and the set indoor target temperature is not large enough, the indoor temperature will rise slowly, and the indoor temperature will still be low for a long time after starting up, which cannot make people feel comfortabl...
