Patent number: 8650903Abstract: 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.Type: GrantFiled: January 7, 2009Date of Patent: February 18, 2014Assignee: Daikin Industries, Ltd.Inventor: Norihiro Takenaka
