A traffic mover includes a mover body forming an accommodation space configured to accommodate a human. The mover body includes a light blocking member and a driving assistance unit. The light blocking member blocks light entering from a front side of the mover body in a moving direction of the mover body. The driving assistance unit enables the mover body to be driven when the light blocking member blocks a forward view of the human in the moving direction of the mover body.

Cooling/heating module and air conditioning device

In the present invention, liquid absorbent is cooled or heated during off-peak hours of electricity demand to prevent the margin between electricity supply and demand from being tightened. A humidity control apparatus switches an absorbent circuit between a regenerated position in which a regeneration circuit is formed, and a humidity-controlled position in which a humidity control circuit is formed. In the regeneration circuit, during a period during which humidity control operation is stopped, outlet and inlet ends of a regeneration passage communicate with each other, and liquid absorbent circulates within the regeneration passage. In the humidity control circuit, during the humidity control operation, a humidity control passage and the regeneration passage communicate with each other, and liquid absorbent circulates between the humidity control passage and the regeneration passage.

Humidity control apparatus

A humidity control module, in which liquid absorbent exchanges air and moisture, reduces a temperature change in the liquid absorbent. A humidity control module includes a partition member and a heat transfer member. The partition member separates an air passage from an absorbent passage. The partition member is wholly or partially formed by a moisture permeable membrane. The liquid absorbent flowing through the absorbent passage exchanges the moisture with the air flowing through the air passage via the moisture permeable membrane. The heat transfer member is provided in the absorbent passage and surrounded by the liquid absorbent. A heat medium flowing through the heat transfer member exchanges heat with the liquid absorbent flowing through the absorbent passage.
