Description

FIELD OF THE INVENTION

[0001] The invention relates to fluid conditioning arrangements, phase change material (PCM) modules and / or components operated in conjunction with these. The invention is of particular applicability to the use of PCM for the ambient temperature control, for example within domestic and commercial buildings.BACKGROUND

[0002] Phase change materials use the latent heat property of material to store thermal energy and can be used in methods of controlling temperature. Phase change materials are either organic such as paraffin or non-paraffin compounds, inorganic (salt hydrates and metallics) or eutectic (organic-organic, organic-inorganic, inorganic-inorganic). Typically, PCMs have a latent heat capacity at least ten times larger than their specific heat capacity.
