The present disclosure relates to an apparatus that can be used to humidify a stream of air that may be delivered to a patient for respiratory assistance during Positive Airway Pressure (PAP) therapy. The apparatus includes a humidification chamber and compartment that receives the humidification chamber in which the humidification chamber is secured in the compartment to enhance thermal engagement, for example, between a heater plate of the compartment and a heater base of the humidification chamber.

A method for maintaining a boiling rate of a base fluid can include a determination of a fluid level of a turbulated base fluid in a reservoir. The fluid level can be determined by measuring at least one first height of the turbulated base fluid above the fluid level with at least a first sensor. The fluid level can be determined by measuring at least one second height of the turbulated base fluid below the fluid level with the first sensor. The method can include the establishment of the fluid level of the turbulated base fluid. The fluid level can be established according to the measured at least one first and second heights. The method can include the graduated introduction of an input fluid into the reservoir. A control valve can gradually introduce the input fluid in proportion to the established fluid level of the turbulated base fluid.

An example of an apparatus is provided. The apparatus includes a build material transport path to transport a build material with air flow. The apparatus includes a humidifying element to receive the air flow and to add moisture to the air flow. The apparatus includes an inlet to introduce ambient air into the build material transport path to decrease moisture content in the air flow. The apparatus includes a valve to connect the humidifying element and the inlet to the build material transport path. The valve is to adjust an amount of ambient air introduced into the build material transport path. The apparatus includes a sensor to detect the moisture content in the air flow and to generate a signal to indicate the moisture content. The apparatus includes a processor to receive the signal to control the valve to maintain a moisture content in the air flow.

A humidifier apparatus may have at least one reservoir configured for holding a liquid. At least one device is for creating vapour from the liquid. At least one ventilator may cause a movement of the vapour exiting the reservoir. One or more light sources project lights on the movement of vapour. A method for operating a humidifier apparatus and creating flame-like vapor.

An air disinfector and humidifier combo is revealed. The air disinfector and humidifier combo includes a tank used for storing water and provided with an air outlet, an electrolytic oxygen generator arranged at the tank for hydrolysis of water in the tank to generate ozone water, an ultrasonic oscillator disposed on the tank for atomizing the ozone water in the tank to produce ozone water mist, an air pump, a bubble refiner connected to an air vent of the air pump and mounted in the tank for generating submicron bubbles, and an electronic control unit electrically connected to the electrolytic oxygen generator, the ultrasonic oscillator, and the air pump for control of their operating time. The air disinfector and humidifier combo provides humidification, disinfection and purification functions. The submicron fine bubbles of the ozone water interact better with dirty air to improve disinfection and cleaning effect.

A humidity adjustment device (10) according to the present disclosure includes a control unit (11) that acquires humidity information indicating humidity of a space part of a manhole and controls the humidity on the basis of the humidity information.

With respect to atmospheric steam generating humidifiers, the present disclosure resolves the problem of end-users not adjusting the drain interval of the humidifier by using an electronic controller to automatically choose an appropriate drain interval without requiring any user input. The electronic controller accomplishes this by receiving input data from a sensor that measures a water quality parameter, automatically determining a drain interval based on the received data, and sending an output control signal to a drain water control valve to execute a drain event in accordance with the drain interval. In some examples, the electronic controller utilizes a look-up table correlating the water quality parameter to a total dissolved solids or cycles of concentration value.

Systems and methods including a container assembly configured to maintain a controlled environment for storing a product therein are disclosed. Controlled environmental parameters may include at least one of the following: temperature, humidity, payload moisture content, solar radiation, magnetism, microwave, or light illumination. In certain implementations, the system includes a payload chamber and a self-contained lid-integrated environmental control unit (ECU) that may be coupled to the payload chamber using a substantially airtight seal. In certain embodiments, the ECU may include a condenser, a humidity controller, a liquid tank and a power source. Certain embodiments may include a warmer, temperature and/or humidity sensors, and/or a lock. Various combinations of the foregoing components and features may be incorporated, depending on the requirements of each particular implementation.

Methods and apparatus for vaporizing liquid into the surrounding environment, including directing liquid from a liquid source to a vaporization port where the vaporization port has lateral dimensions varying from 10 um to 300 um, applying heat to the liquid in the vaporization port with an at least one heating element located in thermal communication to the vaporization port, and releasing vaporized liquid from the vaporization port into the surrounding environment so that fluid is transported through the depth of the structure.

A method and apparatus for operating a dishwasher as a humidifier. The method includes, in response to an input indicating a humidifying cycle of operation, implementing the humidifying cycle of operation. The humidifying cycle of operation can include generating moisture-laden air within a treating chamber of the dishwasher and emitting the generated moisture-laden air to an exterior surrounding the dishwasher. The dishwasher implementing the humidifying cycle of operation or the dish treating cycle of operation, where the humidifying cycle and the dish treating cycle are not simultaneously implemented.
