A Comprehensive Study on a Latent Heat Thermal Energy Storage System and its Feasible Applications in Greenhouses
Abstract Energy crisis is a major challenge in the current world. Latent heat thermal energy storage (LHTES) systems are known as equipment with promising performance by which thermal energy can be recovered. In the present study a comprehensive theoretical and experimental investigation is performed on a LHTES system containing PEG1000 as phase change material (PCM). Discussed topics can be ca...
متن کاملVentilation Performance of Solar Chimney with Built-in Latent Heat Storage
Solar-induced ventilation could be provided by incorporating the solar chimney with buildings. This technique is getting popular in new constructions which are intended to exploit renewable resources to save conventional energy without sacrificing indoor thermal comfort and air quality. Authors [1] [2] have been conducted various experimental and theoretical studies on ventilation performance o...
متن کاملExperimental Investigation on a Combined Sensible and Latent Heat Storage Unit Integrated with Solar Water Heating System
Renewable energy supplies are steadily gaining increasing importance in all the countries. In particular, solar energy, being non-polluting, clean and inexhaustible, has received wide attention among scientists and engineers. Though there are many advantages, an important factor is that solar energy is time dependent energy source with an intermittent character. Hence some form of thermal energ...
متن کاملOptimization of Radiative Heat Transfer inside Greenhouses
This paper presents a multi-objective procedure based on a fully elitist genetic algorithm, GA, able to optimize the radiative heat transfer inside greenhouses used to grow crops. Details of the genetic algorithm used is presented herein but the focus is on the heat transfer. The decision variables are the tube temperature and tube radius, that affects directly the entalphy heating flow, and th...
متن کاملSeparation of power and capacity in latent heat energy storage
The state-of-the-art latent heat energy storage system is equipped with aluminum fins at the heat exchanger pipes in order to compensate the low thermal conductivity of the phase change material (PCM). The necessary amount of fins is directly coupled to the capacity of the storage system, what makes larger systems expensive. The PCMflux concept is developed in order to realize both a controllab...
