<p>PURPOSE:To obtain a thermal energy storing greenhouse having excellent temperature control function throughout a year by circulating underground water, such as well water or upwelling water, at constant temperatures through an underground heat exchanger buried in a shallow part in the ground under the greenhouse floor. CONSTITUTION:The objective extremely simple thermal energy storing greenhouse, obtained by installing an underground heat exchanger 2 in a shallow part in the ground under the greenhouse floor and circulating underground water, such as well water or upwelling water, at a constant temperature from a drawing up well 3 through the above-mentioned underground heat exchanger to store the heat of the underground water in the ground and having energy saving effects.</p> |
