Belüftungshitzecken

Belüftungshitzecken refers to a phenomenon observed in certain building ventilation systems where localized areas within the ductwork experience elevated temperatures, often without a clear external heat source. This can lead to discomfort for occupants, increased energy consumption, and potential damage to ventilation components.

The causes of Belüftungshitzecken are multifaceted and can include poor insulation, air leaks, residual heat from adjacent spaces, and improper system design or maintenance. In some cases, the recirculating air itself can gradually increase in temperature as it passes through the system multiple times, especially if there are minor heat gains within the ducts. Friction from airflow, although generally minimal, can also contribute.

Identifying Belüftungshitzecken typically involves temperature monitoring at various points within the ventilation network. Infrared cameras can be useful in pinpointing hot spots. Addressing the issue often requires a combination of solutions. Improving insulation around ducts, sealing air leaks, and ensuring adequate fresh air intake are common strategies. Adjustments to airflow rates and fan speeds may also be necessary. In more complex scenarios, re-evaluating the system's original design and incorporating heat recovery mechanisms could be considered. Regular maintenance and inspection are crucial for preventing the occurrence and recurrence of Belüftungshitzecken.
