    • PURPOSE:To reduce the consumption of energy necessary for air-conditioning, by heating or cooling with the evaporation heat of a waterfall and the heated air from a waterfall at the peripheral wall of an underground structure and heat exchangers by means of a plurality of thermal sensors. CONSTITUTION:Water is poured into a waterfall 30 for air conditioning by the detection of a specified or higher temperature by thermal sensors 31 and the cooling air conducted through a heat exchanger is blown out to every floor through a first airduct. And, air heated in a heat exchanger is guided to the lowermost floor through ducts to let the air flow in a collecting opening and further, guided almost evenly to the upper floor structure positioned above it through a plurality of inflow openings. Air conditioning is finely controlled at every floor to reduce the necessary energy for air conditioning and practice a rational air conditioning corresponding to the features of the underground structure. Warm stagnant air at the nearby place of the ceiling of the lower floor is rationally utilized in the upper floor to reduce the energy necessary for the air heating.

    • PURPOSE:To make the best use of a space and arrange heavy articles or bulky articles so that they may be picked up by customers easily by installing a compressor within a machine space formed in the upper part of an open space. CONSTITUTION:A housing 10 covers both sides, the top, the rear side and the bottom of an open space 11 which houses merchandises. Only the front side of the open space, which faces customers in a shop, is open. An inner housing 12 is provided with a plurality of showcases 14 and a bucket 16. The bucket 16 is a space designed to house heavy articles, such as milk and raw juice or bulky article, such as cabbages and Japanese white radishes and serves as a deep bucket having a large housing capacity which extends to the very limit of the floor surface. A machine space 22 is installed to the top of the case in such a fashion that it may be in a state of insulation against a circulation pass 18 and what is more, in an open state to the outside of the case. Components of a cooling cycle excluding an evaporator 24d are installed in the machine space 22.

    • PURPOSE:To shorten the term of work by mounting an outer frame on the uppermost section of a peripheral wall section, bearing the outer frame by a bearing means and suspending a floor structure from a bearing beam borne by the outer frame. CONSTITUTION:A peripheral wall 12 is formed by digging down the ground in a cone shape toward a lower section from a ground surface GL. An outer frame 14 is arranged around an uppermost section in a cone-shaped space so as to form the same plane height, and borne by bearing piles 16. One end sections 18b of a plurality of bearing beams 18 are borne to the outer frame 14, and the bearing beams 18 are connected mutually at the other end sections at centers. A plurality of layers of floor structures 20 are hung from the bearing beams 18 by a plurality of steel wires 22. Since an underground structure 10 is suspended in a well-balanced manner by the steel wires 22 at the centers and both sides of the bearing beams 18, rigidity against horizontality of the floor structures 20 is increased, and the floor structures 20 can be lightened, thus improving workability, then reducing cost.
