Efficient phase change energy storing fresh air heat exchange system based on solar energy

Abstract

The invention provides an efficient phase change energy storing fresh air heat exchange system based on solar energy. The efficient phase change energy storing fresh air heat exchange system comprises a heat collection plate, a heat pipe, grading phase change energy storing equipment, a supporting rack glass cover plate and a thermal-insulating back plate; the glass cover plate is mounted at one side of a wall body; the glass cover plate is internally divided into a front cavity runner and a rear cavity runner; air enters the front cavity runner through an air inlet, rises along the front cavity runner and is subjected to heat exchange with the heat collection plate; the air falls along the rear cavity runner after a top-end flowing direction is changed by 180 degrees, and is subjected to heat exchange with the back side of the heat collection plate; the air enters the grading phase change energy storing equipment after being pumped through an air blower; the heat pipe is arranged between the glass cover plate and the wall body; the heat pipe and an outdoor end are connected with the heat collection plate; heat is sent to the grading phase change energy storing equipment after being extracted; and metal supporting racks are arranged above and below the grading phase change energy storing equipment. The efficient phase change energy storing fresh air heat exchange system provided by the invention has the advantages of being simple in machining principle, compact in system, and free from consumption except for the small air blower for guiding the air to flow; and green energy can be efficiently utilized.
