Embodiment Construction

[0041] 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.

[0042] See figure 1 , which is a flowchart of an embodiment of the heating control method based on the present invention.

[0043] Such as figure 1 As shown, the specific process of realizing heating control in this embodiment is as follows:

[0044] Step 11: The air conditioner operates in heating mode, acquires the indoor temperature, and compares the indoor temperature with the first indoor temperature threshold.

[0045] 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 temperature can be achieved using existing technolo...

Abstract

A heating control method, a control apparatus, and an air conditioner. The method comprises: an air conditioner carrying out a heating operation, acquiring an indoor temperature, and comparing same with a first indoor temperature threshold value; if the indoor temperature is not greater than the first indoor temperature threshold value, executing dual PID control; calculating the difference in temperature between the indoor temperature and a set target indoor temperature so as to obtain an indoor temperature difference, and according to the indoor temperature difference, carrying out room temperature PID calculation so as to obtain a first target frequency; calculating the difference in temperature between a coil temperature and a set target coil temperature so as to obtain a coil temperature difference, and according to the coil temperature difference, carrying out coil temperature PID calculation so as to obtain a second target frequency; selecting the larger value of the first target frequency and the second target frequency and taking same as an indoor unit frequency, and controlling a compressor of the air conditioner; and while executing dual PID control, according to the coil temperature, controlling electrical heating. The method can solve the problem of heating being uncomfortable due to the fact that existing air conditioners are slow to provide heating.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular relates to an air conditioner and its control, more specifically relates to a heating control method, a control device and an 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 comfortable quickly, especially in the...
