A heat exchange apparatus (300) includes a first heat exchanger (14), an ejector (11), a first extractor (12), a first pump (13), and a liquid path (15). The ejector (11) produces a merged refrigerant flow using a refrigerant vapor and a refrigerant liquid flowing from the first heat exchanger (14). The first extractor (12) receives the merged refrigerant flow from the ejector (11), and extracts the refrigerant liquid from the merged refrigerant flow. The first pump (13) is provided in the liquid path (15). The refrigerant liquid is pumped by the first pump (13) from the first extractor (12) to the ejector (11).
