Abstract: One embodiment of an improved portable ice cooler that eases access to the cooled contents by integrating in a single apparatus an adjustable ice containment device, a front door, a window, internal lighting and a specialized external contour. The benefits these features provide are a significant reduction in the discomfort and difficulty currently encountered when placing, locating, and removing contents from a current state of the art ice cooler that is accessed from the top or front. The ice containment device further offers the capability of holding a desired level of retraction to the ice within the cooler. The provision for retraction of the ice and thereby the ability to adjust both the proximity of the ice to the items in the cooler as well as the weight of the ice upon those items can be utilized to cool fragile objects.

Abstract: An air conditioning system that includes desiccant compartments for holding a desiccant; a heat exchanger, a blower and a vessel. The heat exchanger can be filled with a heat transfer medium, while the blower blows ambient air by the heat exchanger such that the blown air is cooled and the heat exchanger is warmed such that thermal energy increases and is transferred from the air to the heat transfer medium causing the heat transfer medium to turn into vapor. The vapor is then diffused to one of the desiccant compartments such that the vapor is adsorbed onto the desiccant creating a mixture. Then an energy source is applied to the mixture such that the vapor and desiccant are separated. The separated vapor is transported to the vessel where it is condensed and then sent back to the heat exchanger, such that the system is able to be continuously operating.
