<p>A solar heat accumulating greenhouse has a heat accumulating tank (4C) which absorbs solar heat and accumulates or radiates it in accordance with temperature change to regulate the temperature of the greenhouse. A radiation heat exchanging portion (4B, 4D) is provided at least at one side of an upper or lower portion in the greenhouse, and a heat accumulating tank (4C) is disposed at a lower part in the greenhouse, the radiator heat exchanging portion (4B, 4D) and the heat accumulating tank (4C) being connected to each other through a forced circulation liquid system (4E, 4F). Temperature within the greenhouse may be maintained at a predetermined constant level, with a consequent reduction of expense through saving of fuel cost.</p> |
