Embodiment Construction

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] figure 1 is a structural schematic diagram of an air conditioner control device according to an embodiment of the present invention.

[0027] The control device of the air conditioner of the present invention determines the optimal efficiency frequency control mode (that is, operates in the most power-saving mode under the comfort target expected by the user), so that the air conditioner can be used in actual use and can meet the customer's cooling time and temperature fluctuation requirements At the same time, it runs at the best efficiency frequency for most of the use time to achieve the purpose of energy saving. Different models are equipped with corresponding load-frequency curves and frequency-efficiency curves.

[0028] In an embodiment of the present invention, the air conditioner control device obtains indoor and ou...

Abstract

The invention provides an air conditioner as well as a control method and device thereof, wherein the method comprises the following steps: acquiring an indoor temperature/humidity, an outdoor temperature/humidity and user parameters; calculating an initial heat load or initial cold load according to the indoor temperature/humidity, the outdoor temperature/humidity and the user parameters; calculating the output capacity of the air conditioner according to the initial heat load or initial cold load and a preset cooling rate or heating rate; and determining the frequency of a compressor according to the output capacity of the air conditioner. Through the invention, the air conditioner can run with a frequency generated when the running efficiency of the air conditioner is the optimum efficiency, thereby reducing the power consumption.

Description

technical field [0001] The invention relates to an air conditioner and its control method and device. Background technique [0002] In the related technology, the inverter air conditioner (capacity-controllable comfortable environment adjustment equipment) is controlled by table look-up method or PI fuzzy control method, which has poor performance in the startup stage, slow heating and cooling speed and high power consumption. Moreover, the startup does not operate under the condition of the best energy efficiency ratio, and the frequency of the compressor fluctuates greatly. [0003] Aiming at the problems in the related art that the heating and cooling speed of the air conditioner is slow and the power consumption per unit time is relatively high, no effective solution has been proposed yet. Contents of the invention [0004] The present invention aims to provide an air conditioner and its control method and device, which can solve the problems in the related art that t...
