Document Type and Number:
WIPO Patent Application WO/2020/035946
Kind Code:
A1
Abstract:
A heat source machine according to the present invention comprises: a free cooling unit which has a heating medium circuit that circulates a first liquid heating medium, a first heat source-side heat exchanger that performs heat exchange between the first liquid heating medium and air, a first fan that supplies the air to the first heat source-side heat exchanger, and
a first load-side heat exchanger that performs heat exchange between the first liquid heating medium and a second liquid heating medium; and
a chiller unit which has a refrigerant circuit that circulates a refrigerant, a second heat source-side heat exchanger that performs heat exchange between the refrigerant and air, a second fan that supplies the air to the second heat source-side heat exchanger, and a second load-side heat exchanger that performs heat exchange between the refrigerant and the second liquid heating medium. The chiller unit is installed above the free cooling unit such that, when viewed from a vertical direction, the chiller unit overlaps with at least part of the free cooling unit.
