Abstract

The invention discloses a heating control method for an air conditioner. The heating control method for the air conditioner comprises the steps that the air conditioner operates in a heating mode, and the indoor temperature is obtained and compared with a first indoor temperature threshold value; if the indoor temperature is not higher than the first indoor temperature threshold value, the following fuzzy control is executed, specifically, indoor temperature PID operation is conducted according to the temperature difference between the indoor temperature and a set target indoor temperature, so that a first target frequency is obtained; the coil pipe temperature of an indoor heat exchanger is obtained, and if the coil pipe temperature is higher than a target coil pipe temperature, the first target frequency is determined as the indoor unit frequency; and otherwise, a second target frequency is obtained by increasing the current operating frequency of a compressor, and the larger one of the first target frequency and the second target frequency is determined as the indoor unit frequency for controlling the compressor of the air conditioner, wherein the target coil pipe temperature is determined according to the set target indoor temperature. By applying the heating control method for the air conditioner, the problem of heating discomfort caused by slow heating of an existing air conditioner 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 heating control method for 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 When the in...
