I am looking at Phase Change Materials as a building fabric option and from reading up on the topic theres something I don’t understand. Hopefully somebody can help explain.
I read that when a substance melts it stores latent energy, otherwise charging the material. When the material freezes again it releases this ‘stored’ energy and this is what is utilised for heating or cooling. However, I’ve also read that some substances can store energy during the freezing process and this is where it loses me...
Am I misunderstanding the process or is this specific to certain materials?
Thanks in advance
