Embodiment Construction

[0016] 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.

[0017] 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.

[0018] Such as figure 1 As shown, the specific process of realizing heating operation control in this embodiment is as follows:

[0019] Step 11: The air conditioner operates in heating mode, acquires the indoor temperature, and compares the indoor temperature with the first indoor temperature threshold.

[0020] 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 th...

Abstract

The invention discloses an air conditioner heating operation control method which comprises the following steps: an air conditioner operates in a heating mode, and an indoor temperature is acquired, if the indoor temperature is not greater than a first indoor temperature threshold, fuzzy control is carried out; and when the fuzzy control is carried out, an indoor fan of the air conditioner is controlled to operate at a highest speed. The fuzzy control is specifically carried out as follows: according to a temperature difference between the indoor temperature and a set indoor target temperature, room temperature PID operation is carried out and first target frequency is obtained, a coil tube temperature of an indoor heat exchanger is acquired, if the coil tube temperature is greater than a set coil tube target temperature, the first target frequency is determined as indoor unit frequency, if the coil tube temperature is not greater than the set coil tube target temperature, current operating frequency of a compressor is increased and second target frequency is obtained, the higher value in the first target frequency and the second target frequency is determined as the indoor unit frequency, and the compressor of the air conditioner is controlled. With the application of the air conditioner heating operation control method, the problem that the heating is uncomfortable due to the fact that the heating of an existing air conditioner is slowly can be solved.

Description

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