Description

technical field [0001] The invention relates to the technical field of energy storage and heat exchange, in particular to a heat transfer oil energy storage and heat exchange system and an application method thereof. Background technique [0002] In the process of energy utilization, there is often a contradiction between supply and demand in time and space. Energy storage technology can solve the contradiction between energy supply and demand in time and space, so it is an effective means to improve energy utilization. [0003] At present, the commonly used energy storage fields include wind energy thermal energy storage, solar thermal energy storage, power peak shaving thermal energy storage and industrial waste heat thermal energy storage. There are three main ways of heat storage, sensible heat storage, latent heat storage (phase change heat storage) and thermochemical reaction heat storage. Sensible heat storage is a form of heat storage using the inherent heat capacit...
