Abstract
The present disclosure provides a fan coil unit and an air conditioning system. The fan coil unit includes: a housing, which defines an airflow inlet, an airflow outlet, and an airflow path from the airflow inlet to the airflow outlet; a cross-flow fan, which is located at the airflow inlet to introduce an airflow into the housing; and a heat exchange unit located downstream of the cross-low fan on the airflow path.
Claims7
A fan coil unit, comprising:
- a housing, which defines an airflow inlet, an airflow outlet, and an airflow path from the airflow inlet to the airflow outlet;
- a cross-flow fan, which is located at the airflow inlet to introduce an airflow into the housing;
- and
- a heat exchange unit located downstream of the cross-low fan on the airflow path;
- wherein the housing at the airflow inlet comprises a pair of side walls, an upper volute and a lower volute, an impeller of the cross-flow fan is arranged laterally between the pair of side walls, a drive motor of the cross-flow fan is located outside one of the pair of side walls, and the impeller is surrounded by the upper volute and the lower volute;
- wherein the upper volute comprises a diverging portion extending upward from a front side of the impeller along a divergent line contour by extending from a substantially vertical upward direction to the divergent line contour, and then extending along the divergent line contour into a substantially horizontal direction;
- wherein the lower volute comprises an inclined portion extending obliquely in a backward and downward direction from a rear side of the impeller;
- wherein the lower volute further comprises an enclosing plate surrounding a part of the impeller.
