Description

Technical field [0001] The invention relates to an indoor unit in the field of air conditioning, in particular to an air conditioner indoor unit that can meet the requirements of ventilation and purification, high-efficiency cycle purification, and adjustment of indoor temperature. Background technique [0002] The ideal indoor environment is clean, fresh air, and suitable temperature and humidity. Circular purification can reduce the concentration of dust, formaldehyde, odor and other pollutants in the indoor air, so that the indoor air can be kept clean; ventilation can reduce the concentration of CO and CO2 in the indoor air, and introduce fresh outdoor air into the room to make up for the circular purification. In the process, the inherent defects of inorganic gaseous pollutants such as CO and CO2 cannot be removed; the cycle refrigeration and cycle heating of the air conditioner can keep the room at an appropriate set temperature. [0003] According to the fresh air te...

AI Technical Summary

Problems solved by technology

No fresh air The indoor unit has no fresh air function, and the indoor unit cannot supply fresh air to the room

The negative pressure fresh air indoor unit is equipped with a pipeline to exhaust air to the outside. The exhaust fan exhausts the indoor air, and the fresh air is naturally introduced through the gaps in doors and windows. The disadvantages are: the amount of fresh air is small; the fresh air is not purified; more outdoor pollutants enter through the gaps in doors and windows Indoor; slightly more complicated structure

The positive pressure fresh air indoor unit is equipped with a pipeline to supply air to the room. The blower sends the outdoor air into the room, and the indoor air is naturally discharged through the gaps in the doors and windows. The disadvantages are: the fresh air volume is small; the fresh air is not purified efficiently; the structure is slightly complicated

The two-way fresh air indoor unit is equipped with exhaust and air supply pipelines. The exhaust fan exhausts indoor air, and the supply fan introduces fresh air. The disadvantages are: the fresh air volume is small; the fresh air is not purified efficiently; it cannot prevent outdoor pollutants from entering the room through the gaps in doors and windows; the structure is more complex

[0004] Since the fresh air function is generally not set in the traditional air conditioner, or because the effect of the fresh air function in the traditional air conditioner is not ideal, it is necessary to install ventilation equipment such as a fresh air ventilator in the room to meet the needs of ventilation.
