The prime interest in these fluids is the rise of the heat capacity associated to the phase change, with a consequent pumping power reduction as well as a higher heat transfer versus pressure drop ratio. However, several authors present in their experimental researches heat transfer coefficients that are lower than the heat transfer coefficient for water. This heat transfer coefficient is influenced by several factors, and mainly, by the fluid turbulence level and the PCM concentration. Due to such controversial information, an experimental study is reasonable. The objective of the present study is to make an exhaustive analysis of the recent bibliography to enable a decision on how to approach future researches in a strategic way.

Several samples containing different PCM mass fractions have been prepared and tested in order to study the influence of the quantity of PCM on fire behaviour. The enthalpy–temperature of the PCM curve has been measured using the T-history method, and the effect of the PCM on the thermal behaviour of the cement mortar material has been studied using an experimental setup. With the aim of characterizing the reaction of the composite material to fire, various small scale laboratory tests have been carried out, paying special attention to the production of burning drops during combustion, smoke release and flame persistence.

Compared to water, these new fluids have a higher heat capacity during the phase change and a possible enhancement, as a result of this phase change, in the heat transfer phenomenon.
