The use of solar energy for heating greenhouses in the cold period for a Mediterranean climate is an important issue. In this paper, the thermal performance of a new solar air heater using a packed bed of spherical capsules with the latent heat storage system in east–west oriented greenhouse,...

A free air cooling system that combines phase change material (PCM) with a natural cold source (i.e., cold air) was developed to reduce the space cooling energy consumption in telecommunications base stations (TBSs). Outside cold air, instead of air conditioning system was used to remove heat in...

In this paper, three PCM based foot warmers of cylindrical and rectangular in shape were designed, developed and fabricated to store solar energy during sunshine hours. The stored energy was utilised to warm the feet in the late evening to replace electric heaters. By trial experiment, it was...

A technology that combines phase change materials (PCMs) with a natural cold source is proposed to reduce the space cooling energy of telecommunications base stations (TBSs). First, a mathematical model was developed to assess this technology. Then, a full-scale prototype, named latent heat...

Molten-salt thermocline tanks are a low-cost energy storage option for concentrating solar power plants. Despite the potential economic advantage, the capacity of thermocline tanks to store sufficient amounts of high-temperature heat is limited by the low energy density of the constituent...

Incorporating Phase Change Materials (PCMs) into traditional building structures has been considered as an effective way to reduce the mismatch between energy supply and demand and in turn to minimise energy consumption (cooling/heating energy). For building applications, Phase Change Material...

An experimental study was conducted to evaluate the thermal performance of a new solar air heater collector using a packed bed of spherical capsules with a latent heat storage system. Using both first and second law of thermodynamics, the energetic and exegetic daily efficiencies were calculated...

High-temperature PCM is a key component for storing latent heat. This is necessary for efficient energy storage in connection with the two-phase heat transfer fluid water/steam. Due to the low thermal conductivity of the nitrate salts used for high-temperature PCM storage, it is necessary to...
