1. Ventilation means sending fresh outdoor air indoors and turbid indoor air outdoors. Ventilation means that the air conditioner introduces outdoor fresh air into the room through the air conditioning ventilation pipe, so that the indoor air will not be polluted by closing the doors and windows for a long time. The principle is to use cold air to go down and hot air to go up; When cooling, the air blows upward, which can avoid the cold wind and blow directly on the human body. In addition, cold air is conducive to the circulation of air from top to bottom, and hot air blows down to keep warm, which makes people very comfortable. Keep the air quality in your room, and the oxygen content reaches the level required by human body.
2. The healthy airflow of Haier air conditioner is to solve the air health problems such as clean air conditioner, clean air and fresh air, turn on the healthy airflow, and maintain the indoor air quality, with the oxygen content reaching the level required by the human body. The healthy airflow principle of Haier air conditioning is the principle of using cold air to go down and hot air to go up. Blowing upward during refrigeration can avoid cold air and blow directly at human body. In addition, cold air from top to bottom is conducive to air circulation, and hot air blows down to keep warm, which makes people very comfortable. It can be seen that the purpose and principle of healthy airflow and ventilation are the same, so the healthy airflow of Haier air conditioning is ventilation.
