solar ventilation air heating
The use of a solar collector
to ventilate air. Many industrial buildings contain contaminant producing
processes, where the contaminated air must be removed and replaced with
large volumes of fresh outdoor air. Also, most other buildings require large
quantities of fresh outdoor air to maintain adequate indoor air quality
for occupants. Examples include offices, apartments, and institutional buildings.
Modern houses often require that outdoor air be directly brought in and
heated. Air-based solar collectors
can be used to heat, either partially or completely, outdoor ventilation
air for homes with only 2 m2 of collector area. Also, the collector
can work well with a heat recovery ventilator by reducing its defrost cycle.
In many other countries, the most common collector used for ventilation
air heating is the unglazed
perforated plate solar collector because of its low cost, high efficiency,
and ease of installation.
