Abstract

A portable cooling system for use in conjunction with child carriages incorporating a reservoir of ice and a water pump that directs chilled water through a dehumidifying radiator located in an air handler assembly is herein disclosed. The water continues to circulate through two (2) cooling radiators and returns to the ice and water reservoir by gravity. An electric fan blows air through the radiators where it is dehumidified by the first radiator and cooled by the next two (2) radiators. The air then continues through the air handler wherefrom it is directed toward the child through a flexible duct. A rechargeable battery system is used to power the operation of both the pump and the fan through separate switches. Such an arrangement allows the user to run just the fan for ventilation if cooling is not needed. The cooling system is carried upon the rear of a baby carriage in a stable manner.

Claims

1. A portable air cooling system for dehumidifying and cooling air to an inside space of a child carriage, said portable air cooling system comprising:

a container comprising a cold compartment including chilled water stored therein; and

,

an air handler comprising;

a plenum connected to said container;

a duct connected to said plenum, said duct having a duct collar connected to an end thereof; and

,

a bracket including a clamp affixed thereto;

wherein said bracket is adapted to be removably mated to the child carriage for providing dehumidified and cooled air to the child carriage.

2. The portable air cooling system of claim 1, further comprising:

a dehumidifier located within said plenum;

a plurality of cooling radiators located within said plenum;

a supply line extending from said cooling compartment and ending at said plenum;

a fan positioned between said dehumidifier and said cooling radiators; and

,

a pump connected to said supply line for circulating said chilled water from said cold compartment to said dehumidifying radiator and to said cooling radiators respectively and thereby removing moisture from hot ambient air drawn into said plenum by said fan.

3. The portable air cooling system of claim 2, further comprising:

a return line extending from said plenum and ending at said cold compartment respectively such said chilled water returns to said cold compartment by gravity and said dehumidified and cooled air is directed into said duct.

4. The portable air cooling system of claim 3, wherein said bracket comprises:

a circular mounting aperture and a corresponding slotted aperture formed therein.

5. The portable air cooling system of claim 4, further comprising:

a water-cooled blanket comprising;

a cushion adapted to be removably positioned on the child carriage;

an inlet and an outlet; and

,

a cooling coil in fluid communication with said inlet and said outlet respectively;

wherein said chilled water is supplied through said supply line and passes through said cooling coil before entering said dehumidifying radiator.

6. The portable air cooling system of claim 5, wherein said water-cooled blanket is located in series between said supply line and said dehumidifying radiator such that said water-cooled blanket is cooled by circulation of said chilled water.

7. A portable air cooling system for dehumidifying and cooling air to an inside space of a child carriage, said portable air cooling system comprising:

a container comprising a cold compartment including chilled water stored therein; and

,

an air handler comprising;

a plenum connected to said container;

a duct connected to said plenum, said duct having a duct collar connected to an end thereof; and

,

a bracket including a clamp affixed thereto;

wherein said bracket is adapted to be removably mated to the child carriage for providing dehumidified and cooled air to the child carriage.

8. The portable air cooling system of claim 7, further comprising:

a dehumidifier located within said plenum;

a plurality of cooling radiators located within said plenum;

a supply line extending from said cooling compartment and ending at said plenum;

a fan positioned between said dehumidifier and said cooling radiators; and

,

a pump connected to said supply line for circulating said chilled water from said cold compartment to said dehumidifying radiator and to said cooling radiators respectively and thereby removing moisture from hot ambient air drawn into said plenum by said fan.

9. The portable air cooling system of claim 8, further comprising:

a return line extending from said plenum and ending at said cold compartment respectively such said chilled water returns to said cold compartment by gravity and said dehumidified and cooled air is directed into said duct.

10. The portable air cooling system of claim 9, wherein said bracket comprises:

a circular mounting aperture and a corresponding slotted aperture formed therein.

11. The portable air cooling system of claim 10, further comprising:

a water-cooled blanket comprising;

a cushion adapted to be removably positioned on the child carriage;

an inlet and an outlet; and

,

a cooling coil in fluid communication with said inlet and said outlet respectively;

wherein said chilled water is supplied through said supply line and passes through said cooling coil before entering said dehumidifying radiator.

12. The portable air cooling system of claim 11, wherein said water-cooled blanket is located in series between said supply line and said dehumidifying radiator such that said water-cooled blanket is cooled by circulation of said chilled water.

13. A method of utilizing a portable air cooling system for dehumidifying and cooling air to an inside space of a child carriage, said method comprising the steps of:

providing a bracket and an air handler;

affixing said bracket to said air handler;

installing said air handler onto the child carriage by affixing said bracket to said child carriage;

providing a container having a cold compartment and a pump situated therein;

pouring water into said cold compartment; and

,

filling said cold compartment with ice.

14. The method of claim 13, further comprising the steps of:

providing an air handler having a dehumidifying radiator and a fan and a plurality of cooling radiators situated in series therein respectively;

providing and connecting a water return line to said air handler;

providing and connecting a water supply line to said dehumidifying radiator;

providing and connecting a duct to said air handler;

pumping chilled water from said cold compartment to said air handler such that ambient air is dehumidified and cooled after entering said air handler; and

,

directing said dehumidified and cooled air to said inside space of said child carriage via said duct.
