Abstract

The invention provides a control method and a control device for a variable-frequency air conditioner, and the variable frequency air conditioner. The control method for the variable-frequency air conditioner comprises the following steps: acquiring an energy requirement value of an indoor unit, a set temperature of the air conditioner and the indoor temperature after the heating mode of the variable-frequency air conditioner is started; determining a first target running frequency of a compressor of the variable frequency air conditioner according to the energy requirement value of the indoor unit, the set temperature of the air conditioner and the indoor temperature, and controlling the compressor to run under the first target running frequency, wherein the energy requirement value of the indoor unit is determined according to the nominal refrigeration capacity of the indoor unit. The control method provided by the embodiment of the invention is capable of optimizing the control logic of the variable-frequency air conditioner so that the compressor is capable of reaching a target frequency and is kept running continuously within a reasonable short time after the variable-frequency air conditioner is started, so the heating capacity of the air conditioner under a low-temperature environment is increased, and the heating comfort is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a control method and device for an inverter air conditioner and an inverter air conditioner. Background technique [0002] The frequency conversion air conditioner installs a frequency conversion controller in the air conditioner to adjust the running speed of the compressor, so as to achieve reasonable use of energy; since the compressor of the frequency conversion air conditioner will not be turned on frequently, the compressor will maintain a stable working state, which can make the air conditioner The overall effect of energy saving is more than 30%. At the same time, the frequency conversion control can also reduce noise and prolong the service life of the air conditioner. [0003] In the low temperature environment, when the inverter air conditioner works in the heating mode, the existing inverter control method has an unreasonable control logic for the compresso...
