Title:
ABSORPTION WATER COOLER/HEATER
Document Type and Number:
Japanese Patent JP3157308
Kind Code:
B2
Abstract:
PURPOSE: To make it possible to remove frost adhered to the outdoor heat- exchanger without interrupting the heating.
CONSTITUTION: An indoor heat-exchanger 1, outdoor heat-exchanger 2, cold water heat-exchanger 3, hot water heat-exchanger 4, absorber 5, refrigerant vapor generator 6, and 8-way valve 7 are connected by a piping. A heating medium which is heated by the absorber 5/hot water heat-exchanger 4 is fed to the indoor heat-exchanger 1 by a switching operation of the 8-way valve 7, and is used for a heating or hot water supply, or the heating medium which is cooled by a cold heat being generated when a refrigerant is vaporized by the cold water heat-exchanger 3 is fed to the indoor heat-exchanger 1 to be used for a cooling, for the title absorption type cool calorifier. Then, heating medium pipes 11, 17 are connected by a heating medium pipe 20 equipped with a switching valve 4, and heating medium pipes 15, 18 are connected by a heating medium pipe 21 equipped with a switching valve V5, and a refrigerant pipe 34 equipped with a switching valve V6 and pressure reducing valve V3 is provided between refrigerant pipes 31, 33. Therefore, by allowing a part of the heating medium which is heated by the absorber 5 to flow in the outdoor heat- exchanger 2, a frost adhered to the outdoor heat-exchanger 2 can be melted.
