Abstract
An air management system for an insulated spa cabinet is provided. The air management system monitors the temperature of an equipment air space in the cabinet and vents overheated air in a controlled manner from the cabinet. The air management system comprises an air passageway, formed by a U-trap, between an inlet in the air space and an exterior of the cabinet. The system also comprises an air mover and a sensor. The sensor monitors the temperature in the air space and when the temperature is above a set temperature threshold, the air mover is operated to direct air from the air space through the passageway from the inlet to the discharge for controlled venting of overheated air.

An air management system for an insulated spa cabinet, the cabinet comprising a water containment vessel fit thereto for forming a contained air space therebetween, the air management system comprising:
- an air passageway extending between an inlet in the air space and a discharge to an exterior of the cabinet, the passageway comprising a U-trap having a first plenum extending downwardly from the discharge to a sump, and a second plenum extending upwardly from the sump to the inlet at an upper portion of the air space;
- an air mover between the air space and the exterior of the cabinet;
- and
- a sensor connected to the air space for detecting air temperature in the air space,
- wherein, normally air is trapped in the passageway and in the air space, and when the air temperature is above a set temperature threshold the air mover is operated to direct air from the air space through the passageway from the inlet to the discharge.
A spa comprising:
- an insulated spa cabinet;
- a water containment vessel fit to the cabinet for forming a contained air space between the vessel and the cabinet;
- and
- an air management system disposed in the air space, the air management system comprising:
- an air passageway extending between an inlet in the air space and a discharge to an exterior of the cabinet, the passageway comprising a U-trap having a first plenum extending downwardly from the discharge to a sump, and a second plenum extending upwardly from the sump to the inlet at an upper portion of the air space;
- an air mover between the air space and the exterior of the cabinet;
- and
- a sensor connected to the air space for detecting air temperature in the air space,
- wherein, normally air is trapped in the passageway and in the air space, and when the air temperature is above a set temperature threshold the air mover is operated to direct air from the air space through the passageway from the inlet to the discharge.
An air management system for an insulated spa cabinet, the cabinet comprising a water containment vessel fit thereto for forming a contained air space therebetween, the air management system being located in the air space and comprising:
- a first plenum having an outlet at an upper end thereof, the outlet being connected with an exterior of the cabinet,
- a second plenum having an inlet at an upper end thereof, the inlet being connected to the air space, the first and second plenums operatively connected at respective lower ends to form a U-trap;
- a temperature sensor for determining temperature of the air in the air space;
- a controller for determining if air in the air space is above or below a set temperature threshold;
- an air mover operatively connected to the controller, wherein
- when the temperature of the air at the temperature sensor is below the threshold, the air mover is inoperative, and
- when the temperature of the air at the temperature sensor is above the threshold, the air mover directs air from the air space into the inlet, through the second plenum, through the first plenum and out of the upper outlet for removal of the air from the spa cabinet.
