A necklace misting fan includes a housing, a water reservoir, spray pump system, power supply, fan, and motor within the housing, an air inlet on a front side of the housing, and an air outlet on a top side of the housing. A fan power switch and a spray pump actuator are mounted to the housing. A spray nozzle on the top side of the housing horizontally spaced from the air outlet, is adapted and configured to emit a water spray generally vertically upward and obliquely to a generally vertical upward discharge air stream from the air outlet, when the spray pump actuator is actuated.

A frame for an evaporative cooler includes a bottom channel including a bottom panel and two bottom-side panels, a top channel including a top panel and two top-side panels, and a pair of side channels disposed between, and engaged with, each of the bottom channel and the top channel. The side channels may include a vertical side panel, a flanged bottom, a flanged top, and a pair of flanged sides, where the flanged bottom is engaged with the bottom panel, the flanged top is engaged with the top panel, and each of the pair of flanged sides is engaged with a bottom-side panel of the bottom channel and a top-side panel of the top channel.

A cooling unit enabled to maintain the internal temperature for an extended period of time without an outside electrical power is described. The cooling unit uses a combination of a battery (or one or more battery backs) and one or more phase change materials (“PCM”). In addition, the cooling unit uses one or more airpaths to force cooled air over a group of PCM to maintain the PCM for the event when an external electrical power is discontinued and the power from the battery pack is also depleted. The forced air through one of more airpaths may be always used or only when the cooling unit is operated by only the battery power.

There is provided a solar photovoltaic panel fog/mist cooling system which comprises at least one solar photovoltaic panel, and at least one nozzle arranged at a back side of the at least one solar photovoltaic panel and configured to generate a fog/mist applied onto a back side of the at least one solar photovoltaic panel.

Portage storage containers including controlled evaporative cooling systems are described herein. In some embodiments, a portable container including an integral controlled evaporative cooling system includes: a storage region, an evaporative region adjacent to the storage region, a desiccant region adjacent to the outside of the container, and an insulation region positioned between the evaporative region and the desiccant region. A vapor conduit with an attached vapor control unit has a first end within the evaporative region and a second end within the desiccant region. In some embodiments, the controlled evaporative cooling systems are positioned in a radial configuration within the portable container.
