Summary: Refrigeration is an important part of human comfort, but it consumes nearly 20% of the commercial industry's total energy consumption. The use of fossil fuels for refrigeration systems contributes to global warming, while refrigerants also contribute to global warming and ozone layer depletion. The vapor absorption refrigeration system with water-lithium bromide has the potential to eliminate harmful residuals and carbon emissions. Solar energy, although intermittent, can be used with latent heat storage technology to ensure continuous operation. This review provides insights into suitable phase change materials, storage tank designs, and performance enhancement techniques for integrating latent heat storage with vapor absorption refrigeration systems.

Summary: This study focuses on the vertical wind conditions as a main external factor that limits the energy assessment of high-rise buildings in urban areas. Traditional tools for energy assessment of buildings use a universal vertical wind profile estimation, without taking into account the unique wind speed in each direction induced by the various shapes and configurations of buildings in cities. To address this limitation, the study developed an omnidirectional urban vertical wind speed estimation method using direction-dependent building morphologies and machine learning algorithms.
