The invention relates to the technical field of air conditioners, in particular to a control method of an air conditioner. Through the control method, the problems of poor universality and poor user experience existing in an existing air conditioner control method can be solved. The control method comprises the steps that rotation speed of an inner fan is obtained; according to a fitting formula,frequency raising speed of a compressor in the frequency raising stage is calculated; and the compressor is controlled to raise frequency according to the frequency raising speed, wherein the fittingformula is determined according to the corresponding relation between the rotation speed of the inner fan and the frequency raising speed of the compressor. The fitting formula is determined in advance, then the frequency raising speed of the compressor in the frequency raising stage is calculated according to the fitting formula, and then the compressor is controlled to raise the frequency according to the frequency raising speed. Through the control method of the air conditioner, the universality of the air conditioner and use experience of a user can be improved.

The invention discloses an air conditioner, not only exausted air selectively to upper part or lower part or two, to improve cosiness to user, but also minimized exaust resistance caused by windvane blade. The air conditioner including a main body having a first outlet on upper part of the front and a second outlet on lower part of the front, wherein, one of the left-right windvane blade and up-down windvane blade arranged in the first outlet, the other one thereof arranged in the second outlet.

The invention relates to a system for replenishing air and increasing enthalpy of a frequency conversion compressor with a normally open air supply port, a control method thereof, and a computer-readable storage medium. The method includes: starting up the compressor and controlling the compressor to run at the oil return frequency F1 for 1 minute, then directly increase the frequency to the target frequency Fx to run; after the compressor is started, control the electronic expansion valve to maintain tieme at the initial opening degree EEVini for 3 minutes to avoid low-pressure frosting, and then Turn down to the target opening degree EEVtarget within time4 minutes, and then continue to adjust the opening degree of the electronic expansion valve to keep the specific current gas temperature parameter equal to its target value; control the compressor to run at the target frequency for time2 minutes and then increase or decrease the frequency according to the load Adjust until the current load is equal to the set minimum operating load A, and update the minimum operating frequency allowed for the compressor to operate in real time according to the opening of the electronic expansion valve and the degree of gas superheat during the adjustment process. If the compressor is reduced to the minimum operating frequency The frequency then quits the frequency-up and down-frequency adjustment and keeps running at the current operating frequency of the compressor.

The invention relates to the technical field of air conditioners, in particular to a method for controlling the start-up of an air conditioner. The present invention aims to solve the problems of poor universality and poor user experience existing in the existing air conditioner start-up control method. For this purpose, the start-up control method of the present invention includes: obtaining the rotational speed of the internal fan; calculating the closing speed of the expansion valve according to the first fitting formula; calculating the acceleration of the external fan according to the second fitting formula; Combine the formula to calculate the frequency increase speed of the compressor in the frequency increase stage; control the expansion valve to close the valve at the valve closing speed to the target opening degree; control the external fan to increase the speed to the target speed according to the acceleration; preferably, close the expansion valve to the target speed When the opening degree is set and the speed of the outdoor fan reaches the target speed, the compressor is controlled to increase frequency according to the frequency increase speed. Through the above control method, the start-up control method of the air conditioner of the present invention can improve the universality of the air conditioner and improve the user experience.

The present invention provides a wall-mounted air conditioner indoor unit, which includes a casing, which defines a first air supply port and an air duct connected to the first air supply port. The flow section gradually becomes smaller along the air flow direction; and the air guide member is arranged in the air duct and defines an air outlet gap with its inner wall, so as to guide the air flow blowing toward the first air supply port to the inner wall of the air duct, so that the air flow is in the air duct. The tapered portion of the inner wall of the air duct is guided and gradually converges toward the center of the airflow and flows out of the first air supply port; and the air guide is configured to be movable relative to the air duct, so that the air outlet gap can be adjusted. The wall-mounted air conditioner indoor unit of the present invention has better long-distance air supply and strong air supply effects.
