An air conditioner includes a printed circuit board to which a power device is attached; and a refrigerant jacket which is connected to the power device, and through which refrigerant used for a refrigeration cycle flows. The printed circuit board is accommodated in a switch box. The refrigerant jacket is fixed to the switch box through a heat transfer plate, and the refrigerant jacket and the printed circuit board are connected together by the switch box.

An air conditioner includes a printed circuit board () to which a power device () is attached; and a refrigerant jacket () which is connected to the power device (), and through which refrigerant used for a refrigeration cycle flows. The printed circuit board () is accommodated in a switch box (). The refrigerant jacket () is fixed to the switch box () through a heat transfer plate (), and the refrigerant jacket () and the printed circuit board () are connected together by the switch box ().

An airflow-direction adjustment unit is configured to adjust a direction of air expelled to an exterior from a main body of a heat source unit of a refrigeration apparatus, the airflow-direction adjustment unit. The airflow-direction adjustment unit includes a mounting member and a closing member. The mounting member has-at least one expulsion opening arranged and configured to expel the air from the heat source unit main body. The mounting member is mounted on the heat source unit main body. The closing member is arranged and configured to block some portion of the at least one expulsion opening.

Airflow-direction adjustment unit and heat source unit of refrigeration apparatus

A printed-circuit board () having a power element () and a refrigerant jacket () to which the power element () is thermally connected, with refrigerant circulating therein used in refrigeration cycle, are provided in an outdoor unit casing (). The printed-circuit board () is provided in a switch box (). A face of the outdoor unit casing () has a service opening (). The refrigerant jacket () faces the service opening (), being closer to the front side of the outdoor unit casing () than the power element () as viewed from the service opening ().

An air conditioner is installable in a ceiling of an air-conditioned room and is disposed with a casing in whose top surface is formed a suction opening and in whose bottom surface are formed blowout openings, and in which is formed an air flow path that leads from the suction opening to the blowout openings, a blow fan that is disposed in the air flow path, and a heat exchanger that is disposed in the air flow path.
