Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, specifically to a total heat fresh air ventilation device that is easy to maintain and repair. Background Technology

[0002] In modern life, air-conditioned rooms are mostly enclosed spaces. Poor ventilation and insufficient fresh air in these rooms can cause drowsiness, fatigue, and decreased work efficiency. If these conditions occur in hospitals, wards, and outpatient clinics, it can lead to increased viral concentrations, seriously threatening the physical and mental health of medical staff and patients. In my country, especially in hospital wards and outpatient clinics, over 90% of facilities suffer from insufficient or no fresh air exchange. Therefore, improving indoor air quality in hospital wards and outpatient clinics is of paramount importance.

[0003] Traditional ventilation methods, such as opening windows and installing exhaust fans, result in fresh air carrying a large amount of dust. Moreover, most ventilation equipment requires disassembling and reassembling the ceiling panel to inspect and replace the internal fans, which is time-consuming and labor-intensive. Traditional ventilation devices also have poor internal noise reduction and anti-condensation effects during use. A total heat recovery ventilation device that is easy to maintain and repair is needed to solve this problem. Utility Model Content
