Volumetric heat exchanger is also called storage heat exchanger. It is a heat exchanger with a certain storage volume, that is, it has the dual functions of heat exchange and heat storage, which is the biggest feature of volumetric heat exchanger that distinguishes it from other heat exchangers. Volumetric heat exchanger can be divided into two types according to the shape of the equipment: horizontal volumetric heat exchanger and vertical volumetric heat exchanger.
