Is the cabinet considered a structural part of an HRV?

The cabinet is indeed considered a structural part of a Heat Recovery Ventilator (HRV). The cabinet serves as the housing for the internal components of the HRV, such as the heat exchangers, fans, and filters. This structural element is essential for maintaining the integrity and performance of the HRV system.

The primary purpose of the cabinet is to protect and support the internal mechanisms while also optimizing airflow and energy efficiency. A well-constructed cabinet can also help in minimizing noise and vibrations that could come from the working components inside.

Further context about the design of an HRV indicates that the cabinet’s construction can contribute to the overall effectiveness of the unit in terms of heat transfer and air handling. Additionally, it may also have an insulating role to some extent, although that is not its primary function. As a significant component of the HRV system, the cabinet’s structure directly impacts the system's efficiency, durability, and maintenance, affirming its status as a structural part of the system.
