SOLAR-ASSISTED HEAT STORAGE DEVICE AND SOLAR-ASSISTED WATER SUPPLY SYSTEM COMPRISING THE SAME

摘要

A solar-assisted heat storage device, including at least one molecular sieve heat storage bed and a heat storage water tank. The molecular sieve heat storage bed includes a cylindrical housing and a plurality of heat storage pipes disposed in the housing. The heat storage pipe includes metal pipes having meshes and an adsorbent layer adhered to the surface of the metal pipes. The adsorbent layer includes a molecular sieve adsorbent material adapted to match with water to form a working pair for heat exchange. Two ends of the housing are both configured with sealing valves and respectively connected to an air inlet and an air outlet of an air preheater. One end of the housing is configured with a water inlet connecting to a water outlet of the heat storage water tank, and the other end of the housing is configured with a water outlet.
