Provided is a dehumidification apparatus with good energy efficiency. A moisture absorbing material (polymeric moisture absorbing material 24), which absorbs moisture and swells at a temperature not higher than a predetermined temperature sensitive point, while shrinking and releasing condensed water at a temperature higher than the temperature sensitive point as a result of phase transition, is formed so as to be divided into a plurality of segments which are made apart from each other during dehydration. A rotation motor (21) is used to move the moisture absorbing material (polymeric moisture absorbing material 24) between a moisture absorption region (14a) and a dehydration region (14b). In the dehydration region (14b), the moisture absorbing material (polymeric moisture absorbing material 24) is heated by the heater (25).

A heating, ventilation, and/or air conditioning (HVAC) unit includes a heater housing having a first side wall, a second side wall opposing the first side wall, and a ceiling extending between the first side wall and second side wall. The HVAC unit also includes a first mounting rail disposed across the first side wall at a first distance from the ceiling, and a second mounting rail disposed across the second side wall at a second distance from the ceiling. The first distance is greater than the second distance. The HVAC unit also includes a heating element assembly coupled to the first and second mounting rails and having a planar heating interface extending from the first mounting rail to the second mounting rail.

An exchanger element for use on board a vehicle for a passenger compartment and/or the engine bay of a vehicle. The exchanger element includes an exhaust air flow path and a feed air flow path, wherein the exhaust air flow path and the feed air flow path are separated from one another by partition sections that have heat-transmitting wall regions. The exhaust air flow path forms a fluid connection from the interior of the vehicle to the outer surroundings of the vehicle. The feed air flow path forms a fluid connection from the outer surroundings of the vehicle to a location on board the vehicle. The exchanger element is embedded in a package, the outer surface area shape of which matches the inner dimensions of an installation space on board the vehicle for the installation of the exchanger element.

An air conditioning unit is disclosed herein. The air conditioning unit may include a compressor configured to pump a refrigerant, a valve configured to receive the refrigerant from the compressor, a heat exchanging coil configured to receive the refrigerant from the valve in a defrosting mode and melt ice formed on the heat exchanging coil into condensate, a drip pan arranged to receive the condensate from the heat exchanging coil, a heating element disposed within the dip pan so as to heat the condensate received in the drip pan, and a condensate pump configured to pump the condensate from the drip pan.

A portable humidifier, air-conditioner, and heater wherein the user can connect the device to a power supply and remain comfortable which comprises of a heating element, a condenser, a water housing unit, and a fan system. The heating element is used in combination with the fan to provide warmth when the user is cold. In addition, the heating element may be used to evaporate water from the water housing unit which provides additional humidity for the user. The portable humidifier, air-conditioner, and heater also use a condenser in combination with refrigerant to remove heat from the surrounding air which is used in combination with a fan to cool the user.
