Abstract: The function of the air conditioner is to adjust the air in the room to meet people's requirements for air temperature and humidity, so as to make the human body feel comfortable. However, because of different regions and climates, the functional requirements for air conditioners are also different. Taking the humid climate in the south as an example, excessive humidity can make the human body feel uncomfortable. Direct condensation and dehumidification will cause the air outlet temperature of the air conditioner to be low, which cannot meet people's requirements for temperature. Therefore, an air conditioner with reheating and dehumidification function is proposed here, and a brand air conditioner is used as an example to reheat and dehumidify it. The function is tested and verified to ensure that the air temperature of the air conditioner will not be lower than the user's requirement, and it can also increase the dehumidification capacity.

Key words: Air conditioner, Reheat dehumidification, Temperature and humidity
