Abstract
A heating and cooling device is disclosed. The device has an outer covering, and a plurality of heating and cooling coils within the covering. A plurality of flexible air flow chambers inside the covering provide air flow over the heating and cooling coils, and a plurality of vents exit the outer covering from the plurality of air conduits.
Claims13
A heating and cooling device comprising:
- an outer covering;
- a plurality of flexible air flow ducts inside the outer covering providing air flow from a fan to a plurality of vents on ends of the flexible air flow ducts;
- and
- a plurality of heating and cooling coils arranged within the outer covering on the flexible air flow ducts to provide heating and cooling to air flowing within the plurality of flexible air flow ducts;
- wherein the plurality of vents are affixed at predetermined locations on the outer covering providing for the air flow to exit the outer covering from the plurality of air flow ducts;
- and
- wherein the flexible air flow ducts prevent air from the fan from exiting the outer covering except through the plurality of vents, and from blowing through the outer covering except through the flexible air flow ducts.
4 more elements
A heating and cooling system comprising:
- a flexible air flow duct in fluid communication at a first location with a control and air supply box and having an outlet vent at a second location;
- a heating coil on the flexible air flow duct and in fluid communication with the flexible air flow duct such that the heating coil heats air flowing through the flexible air flow duct;
- and
- a covering blanket containing the flexible air flow duct and the heating coil and having a predetermined location that passes the outlet vent therethrough;
- wherein the control and air supply box provides air flow under positive pressure into the flexible air flow duct and selectively activates the heating coil to provide heated air at the outlet vent;
- and
- wherein the flexible air flow duct prevents air from entering a space between the flexible air flow duct and the covering blanket from the flexible air flow duct.
