Working temperature of phase change energy storage material for melting snow

What is thermal energy storage (TES) with phase change materials (PCM)?

Thermal energy storage (TES) with phase change materials (PCM) was applied as useful engineering solution to reduce the gap between energy supply and energy demand in cooling or heating applications by storing extra energy generated during peak collection hours and dispatching it during off-peak hours .

Can thermal energy storage be used with phase change materials?

Therefore, the use of thermal energy storage (TES) with phase change materials (PCMs) is a very good option to achieve such objective. For industrial applications, two temperature levels are identified of interest, a mid-temperature range between 60 °C and 80 °C, and a high-temperature range from 150 °C to 250 °C.

What are phase change materials (PCMs) for TES?

Phase change materials (PCMs) for TES are materials supplying thermal regulation at particular phase change temperatures by absorbing and emitting the heat of the medium. TES in general and PCMs in particular, have been a main topic in research for the last

Do PCMS absorb energy during a cooling process?

PCMs absorb energy during the heating process as phase change takes place and release energy to the environment in the phase change range during a reverse cooling process. PCMs possesses the ability of latent thermal energy change their state with a certain temperature.

Are viable phase change materials suitable for high-temperature applications?

Highlight of differences with available data. This study reports the results of the screening process done to identify viable phase change materials (PCMs) to be integrated in applications in two different temperature ranges: 60–80 °C for mid-temperature applications and 150–250 °C for high-temperature applications.

How to choose a PCM based on phase change temperature?

After the phase change temperature, the most suitable PCMs will be selected based on the melting enthalpy, and the thermal conductivity. The first property will indeed affect the energy density thus determining the compactness of the TES.
