According to the air conditioner shell structure and the air conditioner, a cold air channel formed in a shell assembly communicates with the side wall of a warm air cavity through the inlet side and the outlet side of the warm air cavity, and an evaporator core installed at the inlet end of the cold air channel can cool inflow airflow to form cold air; hot water may remain in the warm air core installed in the warm air cavity in a refrigeration scene, the first mixing air door is installed corresponding to the outlet side of the warm air cavity, the second mixing air door is installed corresponding to the inlet side, and cold air can be prevented from flowing into the warm air cavity through the inlet side and flowing out through the outlet side by closing the first mixing air door and the second mixing air door during refrigeration. Cold air is prevented from making contact with the surface of the warm air core with residual hot water and absorbing heat, it is guaranteed that the air outlet temperature of the air conditioner is stable, the refrigeration effect is effectively optimized, the refrigeration performance of the air conditioner does not need to be additionally increased or a warm air water valve does not need to be additionally arranged, the structure is simple and compact, and energy conservation and consumption reduction are achieved while cost is reduced.

This invention provides an indoor unit control method, device, and air conditioner. The method includes: determining a target rotation speed based on the current coil temperature; controlling the indoor unit to adjust its rotation speed based on the target rotation speed, so that the indoor unit can continuously operate at the adjusted rotation speed for a first preset time; if it is determined that the next coil temperature is in a first range, controlling the indoor unit to reduce the fan speed based on the adjusted rotation speed; if it is determined that the next coil temperature is in a second range, controlling the indoor unit to increase the fan speed based on the adjusted rotation speed. The indoor unit control method, device, and air conditioner provided by this invention analyze the system pressure value based on the coil temperature and adjust the indoor unit's fan speed accordingly, so that the coil temperature under high-temperature self-cleaning mode is always maintained within the normal temperature range, ensuring that the outlet air temperature is stable at 56°C, improving the efficiency of high-temperature self-cleaning, and avoiding shutdown caused by sudden increases or decreases in system pressure due to unilaterally maintaining the outlet air temperature by adjusting the frequency.
