technical field

The utility model relates to the technical field of air conditioners, in particular to a household air conditioner.

Background technique

Air conditioning refers to a device that can adjust and control the temperature, humidity, cleanliness and other parameters of the ambient air in a building or structure. In recent years, with the improvement of people's living standards, the installation rate of household air conditioners has increased significantly. Nowadays, household air conditioners generally can only process indoor air to meet the needs of cooling, heating, and dehumidification conditions. Except for some window-type air conditioners, there is almost no fresh air introduction device, and the airtightness of the residence is continuously strengthened. After a long-term operation of a household air conditioner in a relatively closed indoor environment, the air conditioner filter will accumulate serious dust, and the indoor air will be filthy and prone to air pollution. Undoubtedly, it has a very adverse effect on people's health.

In addition, in the dehumidification mode of the existing household air conditioners, the outlet air temperature is relatively low, which brings unnecessary coldness to people. Long-term coldness can easily lead to physical discomfort, and the elderly and children are prone to colds, rheumatism and other diseases. Individual products are equipped with air heaters to reheat the air to increase the lower outlet air temperature, but this undoubtedly increases the energy consumption of the air conditioner.

The fresh air dehumidifier is a new air-conditioning equipment used to filter and dehumidify the outdoor air, and then send the relatively dry and target relative humidity air to the room through the fresh air pipe to meet the comfort or technological indoor environmental humidity requirements. As a healthy air conditioner, fresh air dehumidifiers are people's pursuit of high living standards. Based on fresh air, indoor ventilation can be realized. The introduction of fresh air in an organized way can improve the indoor environment to a certain extent, which is beneficial to human health. , and can reduce indoor energy loss caused by unorganized ventilation.
