METHOD FOR STORING WARM AND CHILLED WATERS IN UNDERGROUND AQUIFER AND ALTERNATELY USING IN WINTER AND SUMMER

摘要

PROBLEM TO BE SOLVED: To make it possible to pour sufficiently lowered temperature water in an underwater chilled water zone by providing a chilled water tank and a cooling tower, storing ground water after using it as a warm heat source in a chilled water tank in winter, and supplying the water of the chilled water tank to the tower at night to cool it with cold air at night. ;SOLUTION: In winter, warm ground water is pumped from an underground warm water zone 1 by a lift pump 2, and once stored in the warm water tank 4 of the basement part of a building 3. The operation of the pump 2 is conducted by low-cost midnight power service at night, the tank 4 is insulated by a heat insulator, and the water temperature is held for a long time. The warm water stored in the tank 4 is supplied as the warm heat source for heating to the water heat source heat pump 5 of the facility of the building 3 by a feed water pump 6. The drained ground water of the pump 5 is stored in the chilled water tank 7 of the building 3. A cooling tower 8 installed on the roof of the building 3 is operated by the midnight power service, and chilled water is poured in an underground chilled water zone 10 via a strainer 9. Even not in the northern country of much snowfall, it can be executed, and there is no anxiety of water contamination with melted snow water.;COPYRIGHT: (C)1997,JPO
