A humidifier includes a second housing. A water storage tank is in a housing space of the second housing. The tank is detachable through an attachment/detachment port of the second housing. A third introduction hole communicates an inside and an outside of the second housing with each other in the second housing. A first tank hole communicates an inside and an outside of the tank with each other in the tank. Between the second housing and the tank, a first seal member separates a first downstream side flow path leading to an inside of the tank through the third introduction hole and the first tank hole, from an external space of the second housing. The first seal member extends along an inner surface of the second housing to entirely surround the tank, when viewed from a top of the tank.

Methods and apparatus for vaporizing liquid from a liquid source into the surrounding environment, are disclosed, where the apparatus comprises at least one manifold comprising at least one liquid port formed by a through-hole and at least one ridge structure, wherein the liquid port is in fluid communication with the liquid source and the one ridge structure At least one vaporization port is included in a planar structure connecting a first side of the structure to a second side, in fluid communication with the at least one ridge structure and the surrounding environment, wherein fluid flow through the liquid and vaporization ports is substantially perpendicular to the plane of the structure, and the ridge structures are substantially parallel to the plane of the structure. At least one heating element is present that is in thermal communication to the at least one vaporization port and at least one ridge structure.

Provided is a humidifier, including a machine base, a water tank, a water suction pump, and a water inlet pipe. The machine base is located on the water tank, which includes an atomization water reservoir, a water feed base, a control base, an atomization air channel and an atomizer disposed inside. The water feed base includes a water feed opening and a first outflow opening, and the first outflow opening is in communication with the water tank; a water inlet is disposed on the atomization water reservoir, and water in the water tank will flow into the atomization water reservoir through the water inlet pipe by the water suction pump; the atomizer is in communication with the atomization water reservoir through an atomization opening disposed at the atomization water reservoir, and water vapor flows into the atomization air channel and flows to outside along the atomization air channel.

An air conditioner is provided, including an air flow path, a cooling unit disposed in the air flow path that cools air introduced into the air flow path to condense vapor contained in the air, and a humidification unit that humidifies the air and which includes a storage tank for storing water and a heater for heating water in the storage tank. A discharged-water storage unit is also provided, which stores water discharged from the cooling unit and water discharged from the humidification unit, and an exhaust pipe is connected to the storage tank and configured to discharge water in the storage tank to the discharged-water storage unit. An exhaust valve is disposed midway on the exhaust pipe, and an overflow pipe connects the storage tank and a part of the exhaust pipe on the downstream side of the exhaust valve.

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.

A humidifying system and method for humidifying ambient air is disclosed. The system includes an air circulation unit, a water feed valve, and a water panel in fluid communication with the air circulation and the water feed valve. The air circulation unit and water feed valve are both operably coupled to a controller. The controller is configured to receive on or more signals from one or more sensors, a user interface, and/or a remote control communicably coupled to the controller. The controller may be configured to turn on the air circulation unit and water feed valve in response to a received input—such as a call for humidity. The controller may subsequently turn off the water feed valve when an ambient humidity satisfies a humidity threshold and delay turning off the air circulation unit to enable drying of the water panel while continuing to humidify circulating air.

A cooling and desalination system includes a humidification-dehumidification (HDH) system and an ejector cooling cycle (ECC) system. The HDH system includes a heater for heating saline water, a humidifier for humidifying a carrier gas using the saline water, and a dehumidifier for dehumidifying the carrier gas to obtain desalinated water. The ECC system includes a generator for generating a primary flow of a refrigerant, an evaporator for cooling and providing a secondary flow of the refrigerant, an ejector for the primary flow and the secondary flow to pass through to obtain a super-heated stream, and a condenser. The heater and the generator are configured to connect to a heat source. The ECC system and the HDH system are connected at the condenser for heat exchange between the super-heated stream and the saline water to pre-heat the saline water.
