The present disclosure discloses a water recycling type greenhouse, including a greenhouse body; a water collection device is arranged in the greenhouse body; the water collection device is provided with an air inlet and an air outlet; a condensation portion and a reheating portion are arranged in the water collection device; and the water recycling type greenhouse further includes an energy supply system. Air in the greenhouse body can be poured into the water collection device from the air inlet, flow through the condensation portion and the reheating portion in sequence, and finally be discharged into the greenhouse body again from the air outlet. When the heated air is discharged into the greenhouse body again, a decrease of the temperature of the greenhouse is not likely to occur, and normal growth of plants is not easily affected.

A purification dehumidifier includes a housing, a fan, a dehumidifier assembly, and a purifier assembly. The housing includes an air inlet, a dehumidified air outlet, and a purified air outlet. An air duct in communication with the air inlet, the dehumidified air outlet, and the purified air outlet is formed in the housing. The fan is arranged in the air duct and configured to introduce an airflow into the air duct from the air inlet and blow the airflow in the air duct out from at least one of the dehumidified air outlet or the purified air outlet. The dehumidifier assembly is arranged in the air duct and corresponding to the dehumidified air outlet. The purifier assembly is arranged in the air duct and corresponding to the purified air outlet.

A dehumidifier appliance may include a cabinet, a refrigeration assembly, a collection tray, and an extended water conduit. The collection tray may be disposed below an evaporator of the refrigeration assembly to receive water condensation therefrom. The extended water conduit may be disposed within the cabinet downstream from collection tray.

An HVAC system includes an evaporator coil disposed between a return air duct and a supply air duct. The system includes a compressor fluidically connected to the evaporator coil, and a blower for providing a flow of air through the HVAC system. The HVAC system includes a supply air recirculation line with a recirculation damper and an evaporator bypass line with a bypass damper. A controller of the HVAC determines a recirculation portion of a flow of air and causes the recirculation damper to move to divert the recirculation portion to the recirculation line, so the air recirculates through the HVAC system. The controller determines a bypass portion of a flow of air and causes the bypass damper to move to divert the bypass portion to the bypass line, so the bypass portion does not contact the evaporator coil.

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 humidifier/dehumidifier device is disclosed herein. The humidifier and dehumidifier both, respectively, evaporate water from and condense water into a shared (same) water storage container. The device is fitted with an air intake and at least one air outtake. In embodiments of the technology, one or more of the air intakes receives air from outdoors. One or both of an indoor and/or the outdoor intake is used to receive air based on a determination that an indoor and outdoor humidity and temperature is most efficient to achieve a desired indoor humidity or temperature.
