Talk:Trombe wall

Illustration

This article very badly needs illustration. Here is what I mean:

"A major problem with the Trombe wall is that during overcast days or at night the wall acts as a heat loss, completely defeating the intent of the design. This problem is best addressed by adding insulation between the collector space and the thermal mass, and arranging for the thermal mass to be heated by the air circulating through the collector space via the one-way flaps." I can visualize an ordinary ('unimproved') Trombe wall because I've been familiar with the basics of passive solar since about 1975. Many readers will not be very familiar.

Both the standard and the improved wall designs need to be illustrated, or this passage does little good.

Thanks for considering. -J.R.

I offer the following image of a modified Trombe wall that I added to a earth sheltered solar home that I build starting in 1979 and finishing in 1984 outside Union Missouri. We lived there for about 6 years and enjoyed the warmth and low energy bills. F.K.

Any more examples in Europe, the UK, or the US?

The article only gives examples towards the equator. Would welcome details about its suitability for more northern or southern areas. This little known method could be cheaper and better than solar panels etc, having almost no moving parts. I have found no mention of Trombe walls on UK sites about domestic energy conservation. Could perhaps be retro-fitted on old houses. Perhaps because the cost would be low, and hence gives little or no profit, it is ignored by the energy conservation industry. 92.24.182.64 (talk) 15:52, 11 March 2015 (UTC)

It may be unknown in the UK because it does not require manufacturing of any product, such as solar panels, that can be sold for profit, and hence is not advertised or promoted. Glazing a brick wall, with suitable ducts, should work. A conservatory next to a brick wall should also work. 92.29.116.31 (talk) 11:14, 20 March 2015 (UTC)

Solar Wall

This is also known as a "solar wall", and is described in the book Technological Self-Sufficiency by Robin Clarke, published in various editions around 1976. 2.97.212.103 (talk) 10:10, 7 July 2015 (UTC)

Modified Trombe wall which includes cooling designed.

Marwa Dabaieh, and Ahmed Elbably from Lund University in Sweden recently published (October 2015) an article "Ventilated Trombe wall as a passive solar heating and cooling retrofitting approach; a low-tech design for off-grid settlements in semi-arid climates." in the Journal Solar Energy. (Solar Energy, 2015; 122: 820) (DOI: http://dx.doi.org/10.1016/j.solener.2015.10.005 )

Lund University just released (24 Feb 2016) a Press Release about the article.

A set of test installations are being made in the town St. Cathrine, Egypt according to the news item.
