Latent heat storage method

The method of latent heat storage based on liquid-solid phase transition is available to make smaller the volume of heat storage tank, because of its higher thermal density than that of sensible heat storage. Therefore, a substance which has a large amount of latent heat of fusion is more profitable as a heat storage material. 

Calorimetry gives a powerful method for the simulation of storage reactions. The main thermodynamical parameters which are needed can be provided by the calorimetric test latent heat, specific heat, reaction heat... ... 

In summary, the thermal properties of the electrospun form-stable PCM/polymer composite fibers can be affected dramatically according to different types of PCMs [14, 31, 38, 43, 48] and various PCM/polymer mass ratios or PCM contents [14, 33, 37-39, 41, 43, 48, 49]. The former factor is in charge of the intrinsic thermal properties of the novel thermal-storage materials, because it fixes the phase transition temperatures and limits the maximum value of the latent heats of the composite fibers. The latter one plays a key role in the latent heats of the form-stable PCM/polymer composite fibers but has less effect on their phase transition temperatures. All those novel composite fibers showed good thermal stability and reliability no matter what electrospinning methods were applied.
