Embodiment Construction

[0038] The present invention firstly provides a control method of an air conditioner, figure 1 is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention. see figure 1 , the control method of the air conditioner of the present invention comprises:

[0039] When the air conditioner is in the dehumidification mode and in the automatic wind speed mode, the indoor ambient temperature and the relative humidity of the indoor environment where the air-conditioning indoor unit of the air conditioner is located, and the indoor coil temperature of the air-conditioning indoor unit are acquired;

[0040] Calculate the air dew point temperature of the indoor environment according to the indoor ambient temperature and the relative humidity of the indoor environment, and calculate the temperature difference between the indoor coil temperature and the air dew point temperature;

[0041] Obtaining a preset corresponding wind speed of the...

Abstract

The invention relates to an air conditioner and a control method thereof. The control method comprises the steps that when the air conditioner is in the dehumidifying mode and is in the automatic windspeed mode, indoor environment temperature and indoor environment relative humidity of an air conditioner indoor unit of the air conditioner and an indoor coil pipe temperature of the air conditionerindoor unit are obtained; according to the indoor environment temperature and the indoor environment relative humidity, the air dew point temperature of the indoor environment is calculated, and thetemperature difference between the indoor coil pipe temperature and the air dew point temperature is calculated; according to the temperature difference, preset corresponding indoor fan wind speed isobtained, wherein the wind speed of an indoor fan and the temperature difference are in reverse correlation; and the indoor fan is controlled to run according to the obtained wind speed. Accordingly,when the indoor humidity is large, the indoor coil pipe temperature is rapidly reduced, rapid dehumidifying is achieved, and energy and power are saved; and after the indoor humidity is reduced, the evaporation temperature is high, the phenomenon that the air outlet temperature is too low, cold air blows a person is avoided, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner and a control method thereof. Background technique [0002] The reason why the air conditioner can dehumidify is that the evaporation temperature of the indoor heat exchanger of the air conditioner is lower than the air dew point temperature. When the water vapor in the air is cooled, it will be separated into condensed water, and the condensed water will be discharged outside through the drain pipe to play a dehumidification effect. When the current air conditioner is dehumidifying, after the automatic wind speed is set by remote control, the wind speed is adjusted in stages according to the temperature difference △t between the indoor temperature of the room and the set temperature. The law of wind speed regulation is that when the temperature difference △t is larger, the wind speed is also higher; when the temperature difference △t is smaller, the wind speed is also low...
