A method for the regulated humidification and temperature control of a gas mixture in an inner chamber of an incubator, which inner chamber is sealed off from the surroundings by a housing, includes conducting heat from at least one condensation surface inside the incubator, which at least one condensation surface is separate from the inner surfaces of the inner chamber, is conducted out of the incubator to the outside through a wall delimiting the inner chamber by a heat conductor. Outside the incubator, the heat conductor is connected to a cooling body which releases the heat to the relatively cold ambient air. The method allows dispensing with a cooling unit and at the same time avoid sources of contamination due to moisture condensing out.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source through an inverse-opal wicking structure to a vaporization port where the vaporization port is formed by a through-hole in a structure connecting a first side of the structure to a second side, with all dimensions ranging from 10 um to 300 um, that is in fluid communication with the liquid source and the surrounding environment so that fluid is transported through the vaporization port between the first and the second side. The methods and apparatus includes plurality of heating elements that may be individually and/or selectively addressable by at least three electrode leads.

A climate generator adapted to produce a flow of air at controlled temperature and at relative humidity values (tc, ic) is described, which includes a bubbler (100) which receives a flow of air to be conditioned (Ga), heat exchangers (120) associated with the bubbler (100) to adjust the temperature of the water volume (W) of the bubbler and/or to provide an amount of latent heat of evaporation to the aforesaid volume of water (W); and heaters (180) for heating the flow of air at the dew point (Gb) exiting from the bubbler (100) to the controlled temperature value of the flow of air, wherein the temperature of the volume of water (W) is established as a function of the controlled temperature and relative humidity values (tc, ic), so that the heating of the flow of air at the dew point (Gb) from the temperature of the water volume (W) to the controlled temperature value determines a decrease in the relative humidity (ic) of the flow of air to the controlled relative humidity value.

The present invention provides an improved portable steam humidifier. According to a preferred embodiment, the improved humidifier of the present invention preferably includes a spiral mixing chamber connected to a steam chamber, a spiral outlet duct, an inlet duct and an outlet grill. According to a preferred embodiment, the inlet duct preferably receives air from an inlet fan and directs the air into the spiral mixing chamber where the air is mixed with water vapor from the steam chamber. According to a further preferred embodiment, the air is further directed from the spiral mixing chamber through the spiral outlet duct out through the outlet grill.

The electrical connections of a chamber or enclosure for a water tub can be protected through the use of spill element sensors. The spill element sensors can help to disable the delivery of power to the heater of a water tub in the event that the electrical connections become wet.

An air conditioner including; an air flow path through which air flows; a plate having an air through hole installed in a downstream opening of the air flow path; and a humidifier disposed on the air flow path and capable of supplying vapor into the air flow path. The air flow path has a horizontal channel provided with the downstream opening and extending along a horizontal direction, and the humidifier is disposed on the horizontal channel. The humidifier includes a water storage tank opened upward to an inside of the horizontal channel, and a heater that heats the water in the storage tank. The air conditioner further includes a moisture absorption member that extends in an up and down direction, above a wall part of the storage tank on the side of the plate, or diagonally thereabove on the side of the plate.

A resistance measurement method for a vaporizer includes: reading a resistance value of the vaporizer every first preset time to obtain a first preset number of first resistance values; starting the vaporizer and lasting for a second preset time; reading the resistance value of the vaporizer every third preset time to obtain a second preset number of second resistance values; and calculating an average of the first resistance value and the second resistance value as an initial resistance value of the vaporizer.
