Problems solved by technology
The air supply temperature of traditional household air conditioners is low in summer working conditions, and the difference between the air supply temperature and human comfort temperature is large, and the temperature difference of the supply air is often above 11°C. The wind blowing to the human body will make people feel very uncomfortable, especially for some weak users

The invention provides a control system and control method for an air conditioner indoor unit capable of achieving small-temperature-difference air supply. The control system comprises the air conditioner indoor unit capable of achieving small-temperature-difference air supply, a microcontroller and a first temperature and humidity sensor and a second temperature and humidity sensor which are connected with the microcontroller; the air conditioner indoor unit comprises a shell, the lower portion of the shell is provided with a main air return port, the upper portion of the shell is provided with an air supply port, and the opening degree of the air supply port is adjustable; a main fan, a humidifying unit and an evaporator are sequentially arranged in the shell from bottom to top; an air return fan is arranged in the shell; air blown out of the main fan is subjected to heat exchange through the evaporator, and air blown out of the air return fan is not subjected to heat exchange through the evaporator; and the microcontroller controls the main fan and the air return fan to mix the blown air and deliver the air into a room from the air supply port. According to the control system, the air supply temperature can be increased and the air supply temperature difference can be reduced on the condition that the refrigerating quantity is not changed, and therefore air blown out of theair conditioner indoor unit is softer.
Description
Technical field [0001] This application belongs to the technical field of air-conditioning control, and specifically relates to a control system and a control method of an air-conditioning indoor unit with a small temperature difference and air supply. Background technique [0002] In general, the comfortable temperature of a person is around 26°C and the relative humidity is around 60%. To get such a temperature and humidity environment indoors, the air needs to be processed by a surface cooler to a lower temperature and humidity value, and then sent to the room. The processed air absorbs the residual heat and humidity of the room along the heat-to-humidity ratio line. Eventually reach the temperature and humidity values set by people. However, traditional household air conditioners use the simplest dew point air supply mode, and because of the requirements of humidity adjustment, the air supply temperature must be below 15°C, which is achieved by controlling the start and st...
