Customer ServiceReviewed different types of solar thermal energy storage (sensible heat, latent heat, and thermochemical storage) for low- (40–120 °C) and medium-to-high temperature (120–1000 °C) applications.
Low temperature solar thermal systems operate below 120 °C and are mainly used for domestic water and space heating applications . Fig. 1. System flowsheet for utilization of direct and stored solar thermal energy.
Its advantage is that it can improve the utilization of solar energy and reduce concerns about the safety performance of building materials. In the heat storage system combined with PCMs and buildings, the phase change temperature of PCM usually matches the indoor thermal comfort, which is 18–25 °C.
In passive solar heat storage system, PCMs are usually combined with buildings, which absorb solar radiation to achieve the purpose of heat storage and thermal preservation [ 99 ]. Therefore, PCMs with lower transition temperature (0–30 °C) are the main choice for passive systems.
In order to solve the problem of the time-space mismatch of solar energy and further increase the solar fraction, solar-driven short-term low temperature (<150 °C) heat storage (SSLTHS) systems have received extensive attention.
