HEAT TRANSFER APPARATUS

Document Type and Number:

WIPO Patent Application WO/1997/009570

Kind Code:

A1

Abstract:

A hot heat source heat exchanger (1) receives heat from a primary refrigerant circuit and evaporates a liquid refrigerant. A cold heat source heat exchanger (2) is connected to the hot heat source heat exchanger (1) via a gas flow pipe (4) and a liquid flow pipe (5). An indoor heat exchanger (3) is connected to the gas flow pipe (4) via a gas pipe (6), and to a liquid flow pipe (5) via a liquid pipe (7). A gas refrigerant evaporated in the hot heat source heat exchanger (1) flows to at least the cold heat source heat exchanger (2). In the cold heat source heat exchanger (2), the gas refrigerant is condensed, and the condition of a flow of the refrigerant to the indoor heat exchanger (3) is switched in accordance with a room cooling or heating demand from an object room. In the indoor heat exchanger (3), the refrigerant is condensed or evaporated.
