The invention relates to a portable cooling vented apparatus, comprising: an array made of one or more thermoelectric cooler(s), each thermoelectric cooler having a cold side and a hot side, the cumulative cold sides and the cumulative hot sides of all the thermoelectric coolers define cold and hot sides of the array, respectively; one or more heatsinks at the hot side of the array; and at least one reservoir configured to supply liquid to the heatsink(s), by being adjoined to the heatsink(s) and/or with the aid of one or more liquid channels connected to said reservoir and installed in the interior of the cooling apparatus in proximity to, or within, said heatsink(s); wherein the apparatus is open to the surroundings.

A method of cooling using a thermoelectric cooler is also provided.

An air conditioner includes a housing having a first outlet and a second outlet, a first channel communicating with the first outlet, a second channel communicating with the second outlet, a tank unit configured to hold water for cooling first air and second air, the first air flowing through the first channel, the second air flowing through the second channel, a cooling unit configured to cool the first air by heat of vaporization of water held in the tank unit, a water supply channel for supplying water held in the tank unit to the cooling unit, and a water recovery channel for collecting water remaining in the cooling unit to the tank unit.

The present invention provides a foldably packed temperature adjustment fan, which comprises a water tank assembly, having a water storage cavity; and a shell assembly, mounted on a top of the water tank assembly, wherein the shell assembly comprises a plurality of side plate assemblies for surrounding and forming an airflow cavity and a top plate assembly, at least a part of the side plate assemblies are respectively utilized as a whole body and are detachably mounted on an edge of the top of the water tank assembly, and at least a part of the side plate assemblies can be completely accommodated in the water storage cavity after being detached. The present invention further provides a folding method of the foldably packed temperature adjustment fan. When the temperature adjustment fan of the present invention is used, its appearance is the same as that of a normal unit; during packing, a rear plate assembly, a left side plate assembly and a right side plate assembly can be completely accommodated in the water tank assembly, a front panel assembly does not need to be detached, and as long as the front panel assembly is turned over, fast folding is completed; and the package size is small, associated components are less, and logistics transportation is convenient.

A hybrid evaporative cooler system can include an evaporative cooler, a cooling coil, and a controller. The evaporative cooler can be located in an airstream and the cooling coil can be located in the airstream downstream of the evaporative cooler. The cooling coil can be configured to receive a process fluid from a source. The controller can be configured to operate the hybrid evaporative cooler system in a dry mode on condition that the leaving process fluid temperature set point is greater than the minimum supply fluid temperature.

A refrigerating structure may include an air inlet mechanism, a water tank, and an air outlet mechanism. The air inlet mechanism introduces hot air from a room into the water tank, and comprises a first fan, an air inlet channel, an air inlet pipe and an air pump. The first fan is arranged in the air inlet channel. The air inlet pipe is extended into a bottom of the water tank, and the air pump is arranged at one end of the air inlet pipe extended into the water tank. The water tank is provided with a water inlet pipe and a water discharge pipe communicated with seawater or underground water. The water inlet pipe is arranged at an upper part of the water tank, the upper part of the water tank is open. The air outlet mechanism discharges cold air in the water tank into the room.

A cooling device, for example, for a galley of an aircraft, has a cooling apparatus with a refrigerating medium circuit which contains a first heat exchanger for discharging heat of the refrigerating medium to an ambient air flow and a second heat exchanger for absorbing heat into the refrigerating medium from a cold air flow for the galley. Condensate, namely water, produced by the cooling apparatus or the galley is received in collection devices. The collected water can them be retrieved from the collection devices and preferably introduced in the evaporated state into the ambient air flow so that a discharge of the water in liquid form is no longer required.
