Heat EXchangers (HEX) that are used in City Gate Station (CGS) systems are modeled numerically to recover the exhaust waste heat. It was tried to find the best viscous model to obtain results in accordance with experimental results and to change the heat exchanger design. This HEX is used for recovering heat from exhaust flue gas with a mixture of 40% water and 60% ethylene glycol as the coolin...

Latent thermal energy storage (LTS) systems are versatile due to their high-energy storage density within a small temperature range. In shell-and-tube type storage systems fins can be used in order to achieve enhanced charging and discharging power. Typically, circular fins are evenly distributed over the length of the heat exchanger pipe. However, it is yet to be proven that this allocation is...

Just as the double-pipe heat exchanger is being utilized in an increasing number of applications, its research content also deepening. For this paper, based on air-conditioning cold and source project a building Handan, Hebei Province, 300-meter medium-shallow well was used for heating cooling, corresponding transfer model established. The changes parameters such inlet outlet temperature, excha...
