Abstract

A heat source unit (2) includes an electric component unit (70), a heat source-side refrigerant main flow path (300), and a first refrigerant sub flow path (46) including a first cooling portion (47) that cools a first portion of the electric component unit (70) and a second portion of the electric component unit (70). The heat source-side refrigerant main flow path (300) includes an accumulator (29), a compressor (21), a heat source-side heat exchanger (23), and a heat source-side expansion valve (25). The heat source-side refrigerant main flow path (300) is connected to a utilization-side refrigerant flow path (500) of a utilization unit (3a, 3b) to form a refrigerant circuit (10). The first refrigerant sub flow path (46) branches from a liquid flow path (340) extending from the heat source-side heat exchanger (23) to the utilization-side refrigerant flow path (500) in the heat source-side refrigerant main flow path (300), and causes a refrigerant to flow in a gas flow path (310) between the accumulator (29) and the compressor (21) in the heat source-side refrigerant main flow path (300).
