A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.

Healthy because a mold is not growing inside, doors to a bathroom can be closed all the time, so germs are not escaping out.

Pleasant because an air inside a bathroom is dry and fresh, and mirrors never fog when someone is taking a shower.

Safe because you do not have to use any heating device which can be dangerous.

At the end it is very inexpensive. The yearly cost is only 3 dollars per year.

Methods, systems, and devices for humidifying are described herein. One method includes determining a temperature in a space associated with a humidifying unit, determining a relative humidity in the space, determining an air speed associated with the humidifying unit, and adjusting an amount of water sprayed by the humidifying unit based, at least in part, on the temperature, the relative humidity, and the air speed.

An air-conditioning control device for controlling an air-conditioning apparatus configured to perform air conditioning of a room in which a device that changes an amount of water vapor is located. The air-conditioning control device includes a condensation occurrence determiner configured to determine whether condensation occurs in the room after a certain amount of time elapses by using an amount of change in water vapor, which is predicted by collating device operation data with a device operation table, and an air-conditioning controller configured to change an operation state of the air-conditioning apparatus when the condensation occurrence determiner determines that condensation occurs.

A ventilation fan humidity sensor and case includes a ventilation fan and a housing in which a suction port and an exhaust port are provided, a blowing part that guides air to the exhaust port from the suction port, an orifice that guides air sucked from the suction port to the blowing part via an air exhaust channel that communicates the suction port and the exhaust port, a humidity sensor for detecting humidity of air in the housing, and a humidity sensor case for accommodating the humidity sensor. The humidity sensor case includes a sensor base with a box shape having an opening, a first sensor cap that has a first ventilation hole and covers the opening, and a second sensor cap that has a second ventilation hole and covers the opening inside the first sensor cap.

An indoor unit of an air-conditioning apparatus eliminates a possibility of condensation on a front panel without deteriorating a quality of design. In an off state, an auxiliary air-directing plate is positioned above an up-down air-directing plate inside an air outlet such that a free end of the auxiliary air-directing plate opposite from one end of the auxiliary air-directing plate fixed to a rotating shaft is positioned closer to a rear surface of a casing than is the rotating shaft. In an on state, the auxiliary air-directing plate is rotated in a direction from the rear surface to a front surface of the casing, and the free end is protruded from the air outlet to an outside of the casing.

Embodiments of the present disclosure relate to a climate management system that includes a condensate pan configured to collect condensate from a first heat exchanger of the climate management system, a pump fluidly coupled to the condensate pan, and a nozzle fluidly coupled to the pump, wherein the nozzle is configured to receive the condensate from the pump and direct the condensate toward an airflow across a second heat exchanger of the climate management system.

The present disclosure discloses a control method for a multi-split air conditioning system and a multi-split air-conditioning system, the multi-split air conditioning system, including a compressor and a plurality of indoor units respectively arranged on a plurality of parallel branches, the indoor unit including a fan and the control method including: in a cooling mode, when the multi-split air conditioning system needs oil return, the multi-split air conditioning system opening a branch where an indoor unit in an off state is located, determining whether the indoor unit has reached a dewing condition, opening the branch on which the indoor unit is located, and controlling the fan of the indoor unit according to a determination result.

The present disclosure relates to an air port component and an air conditioner, wherein the air port component includes a first plate body and a second plate body, wherein two longitudinal ends of the first plate body and the second plate body are elastically connected respectively. When the working environment temperature difference is relatively large, even if the difference between the linear expansion coefficients of materials used by the two plate bodies is relatively large, extension or shrinkage generated between the plate bodies due to temperature changes is be compensated by the elastic connection so as to reduce the degree of plastic deformation of the plate bodies due to temperature changes after being used for a period of time, thereby improving the reliability of the operation of the air port component, preventing blockage during the operation, as well as ensuring that the airflow of the air outlet meets the design requirements to prevent condensation due to local overcooling.
