Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE USING SAID HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2015/059832
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat exchanger configured so that the amount of a refrigerant retained within heat transfer pipes is reduced and so that pressure loss in the heat transfer pipes of the heat exchanger is reduced overall. A heat exchanger is formed by serially connecting by means of a flow passage, through which a heat medium flows: a first heat exchanger (101) which is disposed upstream in the direction of flow of fluid to be subjected to heat exchange; and a second heat exchanger (102) which is disposed downstream in the direction of flow of the fluid to be subjected to heat exchange. The heat exchanger is characterized in that: when the heat exchanger functions as an evaporator, a heat medium flows from the first heat exchanger (101) to the second heat exchanger (102) so that the heat medium flows parallel to the fluid to be subjected to heat exchange; when the heat exchanger functions as a condenser, the heat medium flows from the second heat exchanger (102) to the first heat exchanger (101) so that the heat medium flows opposing the direction of flow of the fluid to be subjected to heat exchange; and the sum of the volumes of the flow passages of the first heat transfer pipes of the first heat exchanger (101) is less than the sum of the volumes of the flow passages of the second heat transfer pipes of the second heat exchanger.
