Investigation of Capillary Heat Exchanger Heat Transfer for Heat Pumps in Coastal Regions at Various Times of Daily Operation

Abstract: The optimized design of capillary heat exchangers and their creative engineering uses in buildings are examined in this study. In order to make it easier to implement renewable energy in buildings, this study aims to extract energy using a capillary heat exchanger as the heat pump's front-end device in coastal areas. First, the primary determinants of capillary heat transfer efficiency in coastal regions were investigated in this work. Second, numerical calculations were performed on the capillary heat transfer in the situation of irregular operation patterns in the summer and winter, respectively, in order to increase the capillary heat exchanger's heat transfer efficiency. The results showed that the capillary input and output temperatures differed by 2.1 °C over the eight hours of daily operation of the capillary heat exchanger. Furthermore, the rate of heat transport was 87.1 W/m2. The temperature differential between the capillary inlet and outflow was 2.6 °C during the summer. Furthermore, 107.8 W/m2 was the heat transmission rate. This article supports the use of cutting-edge and environmentally friendly technology in coastal development, such as heat pumps and capillary heat exchangers, which can be applied to the extraction of renewable energy and the usage of buildings in close proximity to the coast.
