A solar heating system (SHS) with a phase change material (PCM) thermal storage tank is proposed with the view that traditional heat water storage tanks present several problems including large space requirements, significant heat loss and unstable system performance. An entire heating season (November-March) is selected as the research period on the basis of numerical models of the SHS-PCM. In addition, taking a public building in Lhasa as the object, the heating conditions, contribution rate of solar energy, and overall energy-saving capability provided by the heating system are analyzed under different PCM storage tanks and different terminal forms. The results show that an SHS with a PCM tank provides a 34% increase in energy saving capability compared to an ordinary water tank heating system. It is suggested that the design selection parameters of the PCM storage tank should specify a daily heat storage capacity that satisfies 70~80% of the entire heating season. A floor radiant system with supply/return water temperatures of 40/35 • C provides the optimal operation and the largest energy saving capability.

Abstract. Unceasing global economic development leads to continuous increase of energy demand. Considering the limited conventional resources of energy as well as impact on the environment associated with its use, it is important to focus on the rational management of energy resources and on supporting the development of new technologies related to both conventional and renewable energy resources. In a number of cases the use of phase change materials (PCMs) turns out to be a reasonable solution. This paper contains a summary of well-studied and known, previously used solutions based on phase change materials as well as novel possibilities, which are under development. It has been decided to investigate this topic due to the wide range of highly effective solutions. The review is focused on selected applications of PCMs for technologies which are designed to improve energy efficiency and on PCMs used in technologies based on renewable energy sources.

“…Increasing inlet temperature rate decreases the melting process [18] As the air flow rate is decreased, the length of the high heat rate plateau is decreased [19] Regarding the freezing process, with the increase of flow rate of HTF i.e. water from 0.033 kg/min to 0.167 kg/min, energy efficiency increases from 63.88% to 77.41% [20] During the solidification process, the inlet temperature of HTF is more significant than the flow rate. As the HTF inlet temperature is increased, the temperature difference between the HTF and the PCM unit increases to lead the larger heat transfer rate [21] Increasing mass flow rate increases the heat transfer rate and the molten volume fraction.…”
