The Smarter Cooler with its Insert Isolator design will provide cooling from four different large areas surrounding the food on all sides, as well as providing a cooler and better insulated bottom area of the cooler, and once the Ice starts to melt and be stored in the Ice Water Reservoir below the food and beverage storage area, an additional surface, five areas, not only has insulation qualities, but also cooling properties, to help keep food and beverages colder longer. The result will be a cooler that keeps the ice water isolated from the food and beverages in the cooler to prevent spoilage of the food, that inevitably drops into the melted ice water in any other cooler on the market.

A refrigeration unit designed for prolonged cooling with intermittent power supplies and adaptability to rotation is described. A spherical design is utilized comprising internal compartments that shift according to orientation of the sphere and enable internal cycling of water at substantially 4 degrees Celsius about an icy core.

Provided is a means for easily producing a plurality of types of flake ice each having a different freezing point and approximately uniform solute concentration. There is provides a flake ice production device. A drum includes an inner cylinder, an outer cylinder surrounding the inner cylinder, and a clearance formed between the inner cylinder and the outer cylinder. A refrigerant supply unit supplies a refrigerant to the clearance. A rotary shaft rotates taking a central axis of the drum as an axis. An injection unit rotates together with the rotary shaft and sprays brine toward the inner peripheral surface of the inner cylinder. A scraping unit scrapes off flake ice that is generated as a result of brine having been sprayed from the injection unit becoming attached to the inner peripheral surface of the inner cylinder, which has been cooled by the refrigerant supplied to the clearance.

The Beverage Cooler Tub is a continuously insulated body with an open top. It is a leak proof container that consists of two or more compartments. The Beverage Cooler Tub is made of hollow plastic walls that are filled with expandable polyethylene foam for insulation that does not allow condensation to form on outer walls when ice is contained inside container. Container is at a depth that allow beverages in bottle or cans to stand and be accessed easily without having to dig through ice. Any walls that separate compartments are part of the continuously insulated body, which provides the same insulation properties from one compartment to another. The Beverage Cooler Tub also has built in hand grips that assist in transportation. It is also designed to house removable condiment insert trays.

A portable air conditioning device. The portable air conditioning device has a housing which defines a hollow interior cavity and a primary compartment. The primary compartment can store ice or other cold materials. A pump is in fluid communication with the primary compartment and pulls water that forms from the melting ice out of the primary compartment into a hollow tubing. A fan blows air across a portion of the hollow tubing and a vent enables the air to pass to a space exterior to the housing. A power source is operably connected to the fan and the pump. The portable air conditioning device can provide cool air to a user by blowing air across the tubing and through a vent, thereby providing a cooling breeze to a user, while keeping food, beverages, and similar items stored within the primary compartment at a cold temperature.

An improved Coanda effect fish pump that allows for improved pump performance with enhanced and unsymmetrical-irregularities features in circumferential flow gaps and orifice flutes that improve water flow distribution and pump performance. Design features improve fish quality during pumping and can be designed to remove sea lice from salmon. The features reduce spinning in the pump, correct for unsymmetrical input water pressure distribution, and reshape water velocities to more effectively remove sea lice.

A heating system for a vehicle includes a reaction space (16) containing a first reactant (22) and a reactant storage space (20) containing or/and receiving a second reactant (24), wherein the first reactant and the second reactant form such a reaction system. A reaction of the first reactant with the second reactant produces a reaction product that releases heat. The second reactant can be separated from the first reactant by introducing heat into the reaction product. A reactant-releasing device (26) releases second reactant from the reactant storage space into the reaction space (16). A first heat removal device (58) removes heat from the first reactant or/and reaction product contained in the reaction space (16). A heating unit (52) heats the first reactant or/and heats the reaction product contained in the reaction space. A reactant-recirculating device (36) recirculates second reactant from the reaction space into the reactant storage space.

Ice hole wraps configured to be positioned in a floor of an ice shelter are provided. An ice hole wrap includes a first circular end, a second circular end, a cylindrical wall extending between the first and second ends, and a height extending between the first and second circular ends. The wall is foldable between a first configuration in which the cylinder has a first height between the first and second circular ends, and a second configuration in which the cylinder has a second height between the first and second circular ends.

An absorption heat pump having a generator, a heat source to heat the generator to drive coolant vapor out of solution, a condenser for cooling the coolant vapor and an expansion valve that expand the coolant fluid as well as an evaporator for at least partial evaporation of the expanded coolant fluid against a medium which is connected to at least one absorber which absorbs the expanded coolant fluid. A hot gas line which branches off from a line for coolant vapor upstream of the condenser and is fluid-connected to the evaporator such that it bypasses the condenser and the expansion valve, a defrosting valve being provided in the hot gas line, by means of which the flow of coolant vapor through the hot gas line can be controlled. The absorption heat pump is operated in a cyclic circulation process.

The cooler is very efficient at keeping certain food items cooler or at least partially frozen. The standard cooler is ideal for boating trips, camping trips and has been in existence for many years. The one drawback is that as the ice melts in the cooler, food items may become soggy and it is not desirable to store items such as cell phones in a cooler because of the danger of water exposure. With the application a drop liner is incorporated into the cooler that will provide the benefits of the cooler while at the same time allow personal items to be stored in the cooler. The drop liner is removable for easy cleaning.
