Control method of indoor unit, controller, indoor unit, air conditioner and storage medium

Abstract

The invention provides a control method of an indoor unit, a controller, the indoor unit, an air conditioner and a storage medium. The control method comprises the steps that the current heat exchange mode of the indoor unit is obtained; multiple temperature values are collected according to the heat exchange mode; when the heat exchange mode is a refrigeration mode, the plurality of temperature values comprise an indoor environment temperature value and an outdoor environment temperature value; when the heat exchange mode is a heating mode, the multiple temperature values comprise a heat exchanger coil pipe temperature value and an indoor environment temperature value; and the multiple temperature values are compared with the corresponding preset temperature values, and the operation states of the first draught fan and the second draught fan are controlled according to the comparison result. Different temperature values can be selected as upper and lower air outlet adjusting bases according to different heat exchange modes, and the flexibility is high; in addition, a plurality of temperature values can be selected as upper and lower air outlet adjustment bases, the outdoor environment radiation temperature is considered during refrigeration, and the indoor environment temperature is considered during heating, so that the upper and lower air outlet mode can be adjusted more reasonably and more finely, and the refrigeration or heating comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method, controller, indoor unit, air conditioner and storage medium of an indoor unit. Background technique [0002] At present, for an air conditioner with an upper and lower air outlet structure, in the cooling mode, when it is detected that the indoor ambient temperature is lower than the preset temperature, it means that the indoor temperature has reached the temperature set by the user. In order to reduce the feeling of cold air, the air conditioner only Open the upper air outlet for cooling, but if the outdoor ambient temperature is high, the radiation temperature will also be higher. If the lower air outlet is closed too early, the cooling effect will not be strong enough, which will affect the user's comfort; in the heating mode When it is detected that the temperature of the indoor heat exchanger coil is lower than the preset temperature, it me...

Problems solved by technology

[0002] At present, for air conditioners with upper and lower air outlet structures, in cooling mode, when the indoor ambient temperature is detected to be lower than the preset temperature, it means that the indoor temperature has reached the temperature set by the user. In order to reduce the feeling of cold wind, the air conditioner only Turn on the upper air outlet for cooling, but if the outdoor ambient temperature is high, the radiation temperature will also be high, and the cooling effect will not be strong enough if the lower air outlet is closed too early, which will affect the comfort of the user; in the heating mode Next, when it is detected that the temperature of the indoor heat exchanger coil is lower than the preset temperature, it means that the temperature of the heat exchanger coil has not reached the temperature set by the user. In order to reduce the feeling of cold wind, the air conditioner only opens the upper air outlet for heating. And if the heating is only performed through the upper air outlet, it will cause slow heating, which will affect the comfort of the user

It can be seen that since the air conditioner can only rely on a single temperature to adjust the upper and lower air outlets in the cooling or heating mode, it is difficult to adjust the upper and lower air outlets in a more reasonable and detailed manner, which will affect the cooling performance of the air conditioner. or heating comfort
