Description

Technical Field

[0001] This utility model relates to the field of fresh air system technology, and in particular to a fresh air device. Background Technology

[0002] Currently, in order to quickly improve indoor air quality, a fresh air unit is often installed in the air conditioning system of a house. It usually works by using a fan and a heat exchanger to recover the waste heat in the exhaust gas and preheat or precool the fresh air introduced into the air conditioning system, effectively reducing the air conditioning load.

[0003] However, with prolonged use of fresh air systems, a large amount of dirt tends to accumulate in the heat exchanger inside the casing, especially in the heat exchanger filter, making maintenance inconvenient. Furthermore, the existing fresh air system installation structure is relatively complex, making it difficult to perform maintenance and remove the heat exchanger and filter, which also leads to higher overall maintenance costs.
