Air conditioner control method and device, and air conditioner

Abstract

The invention provides air conditioner control method and device, and an air conditioner. The control method is applied when the air conditioner is at a low-wind-speed heating module and comprises thesteps of monitoring: monitoring the indoor temperature, acquiring the current indoor temperature, the current indoor humidity and the current first inner pipe temperature of the air conditioner whenthe indoor temperature meets the preset condition, wherein the preset condition comprises: the current indoor temperature is at least x DEG C higher than the indoor temperature before the first duration; calculating: determining the lowest heat exchange temperature according to the current indoor temperature and the current indoor humidity, wherein the lowest heat exchange temperature is the innerpipe temperature required for maintaining the current indoor temperature; and regulating: regulating the inner pipe temperature of the air conditioner to be within a first temperature range, whereinthe first temperature is larger than the lowest heat exchange temperature and smaller than the first inner pipe temperature. By utilizing an air thermal physics characteristic, heat convection betweenupper-layer air and lower-layer air indoors is improved, the room air is uniform, and meanwhile, the heat demand can be met.

Description

technical field [0001] The present application relates to the field of air conditioners, in particular to an air conditioner control method, device and air conditioner. Background technique [0002] For air conditioners, especially wall-mounted air conditioners, when they are working in heating operation, when the indoor unit of the air conditioner is running at low wind speed, the heat transfer effect of the evaporator will become poor, and the condensation temperature will become higher, making the outlet air temperature higher. . At the same time, according to the thermophysical properties of the air, the hot air floats upwards, resulting in an increase in the temperature difference between the air and the bottom of the room. Due to the low wind speed and the setting angle of the air deflector, it is difficult for the hot air to move to the bottom of the room, especially in low humidity. Under the environmental conditions, because the hot air with higher temperature is k...

Problems solved by technology

At the same time, according to the thermophysical properties of the air, the hot air floats upwards, resulting in an increase in the temperature difference between the air and the bottom of the room. Due to the low wind speed and the setting angle of the air deflector, it is difficult for the hot air to move to the bottom of the room, especially in low humidity. Under the environmental conditions, because the hot air with a higher temperature is kept in the upper part of the room, there is a large temperature difference in the vertical direction of the room, so that the user cannot feel the heating effect for a long time, which reduces the user experience.
