Embodiment Construction

[0046] 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.

[0047] See figure 1 , which is a flowchart of an embodiment of the heating control method based on the present invention.

[0048] Such as figure 1 As shown, the specific process of realizing heating control in this embodiment is as follows:

[0049] Step 11: The air conditioner operates in heating mode, acquires the indoor temperature, and compares the indoor temperature with the first indoor temperature threshold.

[0050] 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

The invention discloses a heating control method, a heating control device and an air conditioner. The method comprises the following steps of: enabling the air conditioner to be in heating operation, obtaining an indoor temperature, comparing the indoor temperature with a first indoor temperature threshold value; and performing dual PID control if the indoor temperature is not greater than the first indoor temperature threshold value: calculating door temperature difference between the indoor temperature and a set indoor target temperature, and performing room-temperature PID operation according to the indoor temperature difference, thereby obtaining first target frequency; calculating coiled tube temperature difference between a coiled tube temperature and a set coiled tube target temperature, and performing coiled tube temperature PID operation according to the coiled tube temperature difference, thereby obtaining second target frequency; selecting a greater one of the first target frequency and the second target frequency as frequency of an indoor unit, and controlling a compressor of the air conditioner; and controlling an indoor fan of the air conditioner to operate at a highest air speed while entering dual PID control. The heating control method is applied, so that the problem that heating is uncomfortable as an existing air conditioner is slow in heating can be solved.

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 heating 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, especiall...
