Disclosed is a dehumidifier capable of dehumidifying an indoor space more efficiently. The present dehumidifier comprises: a body having an intake opening and a discharge opening; a blowing fan arranged inside the body so as to draw air into the body through the intake opening and to discharge the same to the outside through the discharge opening; a fan case having a duct arranged inside the body so as to provide a channel through which the air drawn by the blowing fan flows to the discharge opening; a heat exchanger arranged inside the body so as to remove moisture from the air that has flown into the body; and fixed blades that are fixedly installed inside the duct so as to split the air, which has flowed through the channel, to a plurality of discharge paths.

An imaging target includes a light emitter configured to emit visible light from a surface of the imaging target, and an imaging device captures an image of at least the light emitter of the imaging target and acquires image data including the light emitter.

A heating, ventilation, and air conditioning (HVAC) system includes a hot water sub-system including a first heat exchanger and a condenser, a cold water sub-system including a second heat exchanger and an evaporator, and a refrigerant sub-system for transferring heat from the cold water sub-system to the hot water sub-system. The first and second heat exchangers transfer moisture and heat between a liquid desiccant and air. The refrigerant sub-system includes a compressor, the condenser, an expansion valve, the evaporator, and a refrigerant-air heat exchanger. The condenser transfers heat from compressed refrigerant to the hot water sub-system. The evaporator transfers heat from the cold water sub-system to uncompressed refrigerant. The refrigerant-air heat exchanger transfers heat from a portion of the compressed refrigerant to air in a first operating mode, and transfers heat from the air to a portion of the uncompressed refrigerant in a second operating mode.

Systems, apparatus and methods for operating an environmental control system that delivers dehumidified outdoor air into a conditioned space through an air valve. The method includes establishing CO.sub.2 setpoints corresponding to a ventilation outdoor air flow rate and a dehumidification outdoor air flow rate, determining a humidity metric of the conditioned space, and delivering outside air to the conditioned space at the ventilation outdoor air flow rate or dehumidification outdoor air flow rate based upon the humidity metric. The outside air may be tempered with return air from the conditioned space. The dehumidification CO.sub.2 set point is determined by predicting the dehumidification CO.sub.2 set point based on the airflow quantity per occupant and the relationship of the occupant predicted water vapor emission rate and CO.sub.2 emission rate.

An atmospheric water generator apparatus. In one embodiment, the apparatus includes a fluid cooling device. A water condensing surface is thermally connected to the fluid cooling device, the water condensing surface having a superhydrophobic condensing surface, a highly hydrophobic condensing surface, a superhydrophilic condensing surface, a highly hydrophilic condensing surface, or a combination thereof. An air-cooled heat rejection device is in fluid communication with a fluid cooling device. An air fan is configured to induce airflow across the water condensing surface in order to condense and extract water from the atmosphere.

The present disclosure is directed to devices, systems, and products for attracting, capturing and converting atmospheric water vapor into useful liquid water utilizing the thermal dynamic processes of deposition, phase change states and fusion.

A dehumidifier includes a machine body. The machine body includes a case including an air inlet and an air outlet, a condenser provided in the case, an evaporator provided in the case, an axial flow fan vertically provided in the case and side by side with the condenser and the evaporator, and a water receiving tray below the condenser, the evaporator, and the axial flow fan. The water receiving tray is configured to divide the case into an axial flow air duct and a mounting cavity.

A device for regasifying liquefied natural gas (LNG) and co-generating cool freshwater and cool dry air, which device comprises at least one hermetic outer recipient containing an intermediate fluid in liquid phase and gaseous phase, the fluid having high latent heat and high capillary properties, traversed by at least one intermediate fluid evaporation tube inside the tube flows moist air whose moisture condenses, at least partly, in a capillary condensation regime on its inner face and on its outer face the liquid phase of the intermediate fluid evaporates, at least partially, in a capillary evaporation regime, and traversed by at least one LNG evaporation tube on which outer face the gaseous phase of the intermediate fluid condenses at least partially, under a capillary condensation regime, and inside the tube, the LNG is heated and changes phase and the regasified natural gas (NG) is heated to a temperature greater than 5° C.

A dehumidifier with a pre-cooling device includes a compressor, a condenser, an expansion device, a microchannel pre-cooler and an evaporator assembly. During operation, moist air enters from an air inlet of the dehumidifier, and passes through the microchannel pre-cooler to make the moist air to reach a saturated steam state and passes through the evaporator assembly for heat exchange to condense and dehumidify the moist air, and the dehumidified air passes through the condenser for heating and finally discharged from the air outlet, so that the water vapor in the moist air can be condensed into a liquid better to improve the condensation and dehumidification effects of the evaporator and reduce the air humidity effectively, so as to improve the dehumidification effect of the equipment.

A portable dehumidifier includes a remote moisture sensor that is capable of being physically positioned at a location that is remote from a portable housing of the portable dehumidifier to sense moisture at the location. In some instances, the remote moisture sensor may be positioned near or on clothing in order to sense the dryness of the clothing and/or positioned near or on floors, walls, furniture, etc., in order sense the dryness thereof in connection with water damage restoration.
