A humidifying device includes an air inlet, an internal air passage through which air taken in from the air inlet passes, a first thermometer that measures a temperature of the air taken in from the air inlet, a first hygrometer that measures a humidity of the air taken in from the air inlet, a cooler installed in a path of the internal air passage, and a cooling control unit that controls the cooler. The cooling control unit changes a cooling intensity of the cooler in a case where values measured by the first thermometer and the first hygrometer are out of a predetermined range.

A fresh air conditioning system includes a first cooling device having a first cooling end and a first heating end; a dehumidifying rotary defining a first section and a second section. An airflow switching device directs a fresh airflow toward the first cooling end or the first heating end, and then flows to the first section. A return airflow passes through a first heat exchanger, and conducts heat exchange with the other end of the first cooling device, and then flows to the second section. Or switching opposite ends of the first cooling device to selectively cool or heat, the fresh airflow conducts heat exchange with one end of the first cooling device, and then flows to the first section. The return airflow conducts heat exchange with the other end of the cooling device and then flows to the second section.

The present invention relates to an air-conditioning device comprising: a case having an interior divided into a first area and a second area, having an indoor inlet and an indoor outlet formed therein such that the first area and an indoor space communicate with each other, and having an outdoor inlet and an outdoor outlet formed therein such that the second area and an outdoor space communicate with each other; a barrier arranged between the first area and the second area inside the case; an indoor blowing fan arranged in the first area so as to form a flow of air from the indoor inlet to the indoor outlet; an outdoor blowing fan arranged in the second area so as to form a flow of air from the outdoor inlet to the outdoor outlet; a first thermoelectric element comprising a first indoor heat exchanger arranged in the first area so as to exchange heat with air passing through the first area, and a first outdoor heat exchanger arranged in the second area so as to exchange heat with air passing through the second area; a case lower-surface formed on the lower surface of the case so as to have an open upper side such that condensed water generated from the first thermoelectric element is collected; and a second thermoelectric element arranged between the first thermoelectric element and the case lower-surface so as to heat the condensed water. The first area and the second area are connected between the case lower-surface and the second thermoelectric element such that the condensed water is distributed across the first area and the second area. The present invention is advantageous in that indoor cooling/heating can be performed without no separate compressor, outdoor unit, and the like, and condensed water can be effectively evaporated.

A temperature control unit may include one or more thermoelectric cooling elements coupled to a conditioned space heat exchanger and an unconditioned space heat exchanger. The unit may further include one or more conditioned air fans configured to move air from a conditioned space over the conditioned space heat exchanger. The unit may also include one or more unconditioned air fans configured to move air from an unconditioned space over the unconditioned space heat exchanger. The unit may further include a power supply configured to change a polarity and level of power to the one or more thermoelectric cooling elements.

A humidifying device includes an air inlet, an internal air passage through which air taken in from the air inlet passes, a first thermometer that measures a temperature of the air taken in from the air inlet, a first hygrometer that measures a humidity of the air taken in from the air inlet, a cooler installed in a path of the internal air passage, and a cooling control unit that controls the cooler. The cooling control unit changes a cooling intensity of the cooler in a case where values measured by the first thermometer and the first hygrometer are out of a predetermined range.

An apparatus for water purifying and dehumidifying with an air purifying system purifies air and purifies condensate water produced by dehumidification such that the condensate water can be used as drinkable water, as a single product, whereby various functions are given to one product. Accordingly, there is an effect that the manufacturing cost of the product is reduced and expenses by customers are decreased, whereby it is possible to improve competitiveness of the product in terms of practical use.
