Title:
HEAT TRANSFER DEVICE
Document Type and Number:
Japanese Patent JP3276529
Kind Code:
B2
Abstract:
PURPOSE: To form a circulating cycle regardless of the positional relation between a high-temperature heat source and a low-temperature heat source and transfer heat without employing any pump by a method wherein the phase of operating medium is changed in a gas section in a second liquid receiver by an auxiliary air heat exchanger while the operating medium is moved by the change of pressure due to the change of phase to effect heat transfer.
CONSTITUTION: The first opening and closing valve 14 of a communicating pipe 12 and the second opening and closing valve 15 of a communicating pipe 13 are opened, a second liquid receiver 1 is connected to an auxiliary heat exchanger 4 through a liquid pipe 5, raised upwardly, and a pipeline at a lower part and a gas section is sealed whereby a pressure in the second liquid receiver 1 is increased by evaporation. Accordingly, liquid refrigerant flows into a utilizing side heat exchanger 6 at an upper part by the pressure through a liquid pipe 5. In this case, heat exchange between the liquid refrigerant and indoor air (20-30°C) is effected in the heat exchanger 6 whereby the indoor air is vaporized and cooled, then, is used for room cooling. The evaporated refrigerant is moved into a low-temperature heat source or a heat source side heat exchanger 8 through a gas pipe 7 due to a temperature difference.
