Abstract

The invention provides a heat exchanger for heat storage and a fresh air system for controlling PM2.5. The heat exchanger for heat storage comprises a heat source inlet, a heat source outlet, a cold source inlet, a cold source outlet and a shell, wherein a plurality of heat storage blocks are arranged in the heat exchanger shell and stacked together, a first hole is formed in each heat storage block, and a channel formed by each first hole is used for circulating the heat source; the heat source enters from the heat source inlet, passes through the first hole and then is discharged from the heat source outlet; and the heat storage capacity of a heat storage material is gradually reduced along a flowing direction of the heat source. The invention aims at providing a novel heat exchanger forheat storage and a fresh air system. The cost of heat storage material can be saved, and the heat storage effect can be improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to a heat storage heat exchanger and a fresh air system. Background technique [0002] With the continuous development of the economy and the massive consumption of energy, energy conservation has become a topic of global concern. Renewable energy such as solar energy, wind energy, and geothermal energy, and the utilization of industrial waste heat and waste heat have become the focus of research and development in various countries. However, these energy sources have Due to the characteristics of discontinuity and instability, the research on energy storage technology is particularly important. Heat storage technology is one of energy storage technologies, and an important part of heat storage technology is the design of phase change heat storage heat exchanger. The common phase change regenerative heat exchanger consists of two tubes set together, and the cold and hot flu...
