| (54) | Heat pump position checking method in heat pump system and heat pump system |
| (57) 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).
