<P>PROBLEM TO BE SOLVED: To provide a storage type solar heat collector, capable of resolving detects such that a conventional solar heat collector of a solar heat heating system for an agricultural house is expensive and uneconomic, and even if the solar heat collector can be inexpensively installed in the house, it is poor in efficiency since 1/3 of the cultivated area is used as the installation area. <P>SOLUTION: The system includes a flat plate solar collector capable of collecting heat from both surfaces thereof, which is provided horizontally at a vertically middle position on the north side inside the agricultural house installed to lie east and west; and a reflector provided to guide solar heat beams to the collector from the upper side and from the lower side to collect heat. The heat is stored in a soil heat accumulation layer within a fortified soil layer. According to this, the heat collection amount of solar heat per heat collection area of the collector is increased, and the installation space of the collector is suppressed to 20% or less of the cultivated area. <P>COPYRIGHT: (C)2013,JPO&INPIT |
