PROBLEM TO BE SOLVED: To provide a heat source unit of a refrigeration device of high safety.SOLUTION: Fans 61, 62 generate airflow so that the air passed through a third space SS3 is sucked to a first space SS1 from a first suction port 40a and passed through a refrigerant gas sensor 42, and the air passed through a forth space SS4 is sucked to a second space SS2 from a second suction port 40b. The first space SS1 and the second space SS2 of an electric component box are separated from each other. A casing 50 includes the third space SS3 in which a heat source-side refrigerant circuit exists, and a forth space SS4 separated from the third space SS3 and free from the heat source-side refrigerant circuit. A refrigerant gas sensor 42 for detecting a refrigerant leaking from the heat soure-side refrigerant circuit is accommodated in the first space SS1, and at least a part of the plurality of electric components for driving an actuator is accommodated in the second space SS2.SELECTED DRAWING: Figure 10 |
