This invention is a zone storage heat exchanger. In its most basic terms, the heat exchanger is comprised of a main body filled with an energy storage material. There is disposed within the main body a heat transfer fluid annulus for flow of the heat transfer fluid therethrough. The annulus has a hollow inner portion which is filled with an energy storage material.

Zone storage heat exchanger

A double-layered thermal energy storage module comprising front and rear vertically disposed storage sections separated by a flat sheet positioned therebetween. The upper end, lower end, and sides of the storage sections are sealed except for inlet and outlet connections. Each of the storage sections are provided with a plurality of spaced-apart phase change material storage tube segments having fluid flow channel segments positioned therebetween. The segments in the front section are disposed at an opposite angle to the segments in the rear section. The ends of the tube segments in the front section communicate with ends of tube sections in the rear section. The ends of the channel segments in the front section communicate with ends of channel segments in the rear section. The tube segments are filled with a phase change material while the channel segments are filled with a heat transfer fluid.
