What is the latest replacement air-conditioning system?

An air-conditioning system of the museum is set with the aim of maintaining constant temperature and humidity to protect the artworks. The conditioned air is blown from outlets and drawn into inlets, but normally the inlets and outlets are installed locally so that there is air flow near the walls and ceilings. In this museum an air-conditioning system has been introduced that minimizes the air flow so that the artworks are not affected. By using the joints in the floor as outlets and using the louver slits in the ceilings as inlets, the air is replaced overall, and a uniform air environment is created.
