Can PCM be used for thermal storage?

Using PCM for thermal storage can improve the efficiency of cooling, as well as operational security. The most efficient solution, regarding energy consumption, is if PCM is used to shift the cooling load such that cooling itself can be done by free air.

What is a PCM & how does it work?

Both active and passive space heating and cooling systems can make use of PCMs. To boost their thermal storage capacity in passive systems, PCMs can be encased in building materials like concrete, gypsum wallboard, the ceiling, or the floor. They have the ability to immediately absorb solar energy or thermal energy via natural convection.

Are PCMS a good energy storage method?

PCMs offer substantially better energy storage densities than current sensible thermal storage techniques, and the heat is stored and released at nearly constant temperatures. Both active and passive space heating and cooling systems can make use of PCMs.

Where is the PCM storage unit located?

The PCM storage unit is placed on upper of an inclined collector, near the solar collector or under the solar collector. To avoid the leakage, the PCMs are encapsulated in rectangular, cylindrical, and spherical container ( Figure 12; Table 3 ).

What are the advantages of PCM?

The high heat storage capacity of PCM in a small temperature range can be a major advantage with regard to the size of a storage, but usually PCM compete with other technologies, primarily hot and cold water storage.

What is PCM integrated cooling system?

PCM integrated cooling systems can make room air drier without elaborate cooling, compression, or other complex systems or controls. After the drying task is complete, the desiccant is dried using hot air in a process called regeneration and is ready to dry more air. Obtained dry process air sent to conditioning by prior mild cooling.
