Abstract
This disclosure relates to a smoke detection system for an enclosed area. The smoke detection system comprising a housing having an inlet and an outlet. The smoke detection system also having a divider within the housing, wherein the housing includes a first compartment to receive air flow from the inlet, a turning portion configured to direct flow to a second compartment in communication with the outlet, and a sensor that senses smoke provided within the first compartment. A method is also disclosed.
Claims16
A smoke detection system for an enclosed area, the system comprising:
- a housing having an inlet and an outlet;
- a divider within the housing, wherein the housing includes a first compartment to receive air flow from the inlet, and a turning portion configured to direct flow to a second compartment in communication with the outlet;
- and
- a sensor configured to detect smoke in an air flow, said sensor provided within the first compartment;
- wherein the first compartment is in communication with the inlet, the second compartment is in communication with the outlet, and the inlet and outlet are provided in a common side of the housing;
- and
- wherein the first compartment receives air flow from the inlet in a first direction and the second compartment returns air flow to the outlet in a second direction opposite to the first direction, wherein air flows in the first direction downstream of the sensor and upstream of the turning portion.
A method for detecting smoke in an aircraft, the method comprising:
- (a) directing air flow into a first compartment of a housing in communication with an inlet, the first compartment having a sensor to detect smoke in the air flow, wherein the air flows into the first compartment in a first direction, and wherein, downstream of the sensor, the air flows in the first direction;
- (b) directing the air flow to a turning portion, wherein the air flows in the first direction upstream of the turning portion;
- and
- (c) passing the air flow to a second compartment in communication with an outlet, wherein a divider separates the first and second compartments, and wherein the air flows from the second compartment to the outlet in a second direction opposite the first direction.
A smoke detection system for an enclosed area, the system comprising:
- a housing having an inlet and an outlet;
- a divider within the housing, wherein the housing includes a first compartment to receive air flow from the inlet, and a turning portion configured to direct flow to a second compartment in communication with the outlet;
- and
- a sensor configured to sense smoke in an air flow, said sensor provided within the first compartment, wherein the first compartment includes splitter vanes to split the air flow adjacent the inlet, and wherein the housing includes turning vanes that turn the air flow towards the sensor;
- and
- wherein the first compartment receives air flow from the inlet in a first direction and the second compartment returns air flow to the outlet in a second direction opposite to the first direction, wherein the air flows in the first direction downstream of the sensor and upstream of the turning portion.
