Abstract

There is provided a heat pump position checking method in a heat pump system capable of correctly checking the positional relationship among heat pumps and achieving efficient operation and improvement in reliability and a heat pump system. A heat pump system (1) is a heat pump system in which a plurality of heat pumps (2) are connected to a water pipe (11), and a water heat exchanger of each heat pump (2) exchanges heat with water flowing through the water pipe (11). The heat pump system (1) includes an operation control unit (14) which puts one heat pump (2) into cooling operation or heating operation, a water temperature detection unit (15) which detects the temperatures of water in the water pipe (11) flowing into the plurality of heat pumps (2), and a positional relationship estimation unit (16) which estimates the positional relationship among the plurality of heat pumps (2) on the basis of the heat pump (2) in cooling operation or heating operation and the temperatures of water detected at the plurality of heat pumps (2).
