What is the purpose of a Trombe wall in solar energy applications?

A Trombe wall is designed specifically to absorb solar radiation and act as a thermal mass. Its structure typically consists of a south-facing wall made of materials with high thermal mass, such as concrete or brick, which can effectively capture and store heat from the sun during the day. This stored heat is then gradually released into the building during cooler periods, helping to maintain a comfortable indoor temperature.

This feature makes the Trombe wall an effective passive solar heating system. By absorbing solar energy, it reduces the need for conventional heating systems, leading to increased energy efficiency in buildings. The other options do not accurately describe the primary function of a Trombe wall; it is not intended to filter air, provide structural support in a typical sense, or store chemical energy.
