HEAT-STORAGE MODULE BASED ON LATENT HEAT WITH HIGH HEAT-TRANSFER RATES

摘要

Heat-storage module based on the transmission of heat from a heat-transfer fluid to a phase-exchange material in a channel delimited by metal plates in the form of a spiral which form an internal element of the module. The heat-transfer fluid is circulated via the channel outside the channel that contains the phase-change material. The internal element has a conical spiral longitudinal cross section in the upper and lower parts. This means that, once the fluid is running through the module from top to bottom, the condensate remains at the bottom, automatically separated out from the vapour, which may be recirculated.
