Title:
ABSORPTION COLD/HOT WATER MACHINE
Document Type and Number:
Japanese Patent JP3172295
Kind Code:
B2
Abstract:
PURPOSE: To expedite a switching operation from a heating operation to a cooling operation in an absorption cold/hot water machine in which cooling water of heat exchangers is cooled by a radiator and circulated.
CONSTITUTION: An absorption cold/hot water machine 100 stops circulation of cooling water 32a passed through an absorber 1.a condenser 23 at the time of heating cold/hot water 35b as heated water by operating switching valves V3, V8, V5, circulates the water 32a by a pump P3 at the time of cooling the cold/warm water 35b as cold water, and cools it via a radiating cooler 51 of a radiator 50. At the time of heating, the cooling water held from a conduit 31 to a conduit 34 becomes a high temperature. Accordingly, the valve 8 is closed, the valve V7 is opened to return cooling return water 32b to a reservoir 59 via a bypass B1, thereby expediting a temperature drop of the cooling water. the top of the water is slow, a switching valve V9 is opened to mix city water 57 with storage water 59A, thereby accelerating temperature drop.
