    |
|
| I am hoping to use phase change materials in my trombe wall for thermal storage. I've read research showing eutectic salts and phase change waxes to be several times more efficient than water at storing enery. However, I have not found any pratical info on how to use or where to purchase them. Anyone have any practical info? |

Sorry to disappoint but maybe we can share our efforts? I'm in the same position - I've done enough basic research to convince myself that this is worth further investigation but am now disappointed to find that there is very little available "off the shelf" in this area. I was hoping _not_ to be doing any trail blazing - I just want to heat a new extension to the house which we are planning - but it looks like I may have to! |

hey guys,
any information on PCM's? I'm trying to write an assignment on the subject ad am also finding information thin on the ground. If I do find something I'll post it here. |

Here is a good place to start:
http://freespace.virgin.net/m.eckert/index.htm
Some of the links at the bottom lead to further interesting material.
When considering the use of inorganic salts (hydrates) there are 2 unexpected issues (at least, they came as a surprise to me!): supercooling, and a limitation on the number of cycles available. I'd like to know more about these issues.
I'm designing a heat store using air for the heat transfer. I've found one research paper about such a system published by some researchers in Lithuania. I haven't got the paper to hand but will post a reference if anybody is interested. |

Hi everybody,
I'm currently working on a project about sustainable housing. I'm searching for alternate way's to store heat. I found some information about PCM, but I'm looking for references.
Could someone help me? |

hi everyone,
for what kind of references you are looking for.
I heard that there are a lot of different trials and test projects to integrate PCMs in different ways, into building construction for heating or cooling purposes.
there are several companies which produce pcm over the world like India, Germany etc.
For a seminar paper about Phase Change Materials I stayed in contact with a company in Germany called Doerken, Herdecke (www.doerken.de). I discussed with the responsible commericial manager Jan and he informed me about a facade product for heating purposes. It will be produced at doerken under licence of a switzerland company called (www. glassX.ch). With this product they have realized nearly 10 projects with very great success.
Unfortunatelly on Doerken websiter there are no information available, but have a look at the website of glass x. very interesting product. |

in my eyes it should be not so simple like you like. PCM are in a limited temperature range very effective, but not over a very wide range. I'm not sure, but might be possible that Doerken, Herdecke in Germany can advice you how it could work (www.doerken.de). |

The European Union funded REVIVAL project features a building that incorporates Phase Change Materials for cooling. The building is Daneshill House, part of Stevenage Borough Council. Information can be found here:
