1. A system to create an indoor thermal environment based on ductless personalized ventilation (DPV) and impinging jet ventilation (IJV), comprising: an IJV duct and a DPV device; wherein the IJV duct is installed on a wall of a room, an air inlet of the IJV duct is connected to an air supply duct of an air conditioning system, an air outlet of the IJV duct is located inside the room and close to ground in the room, the DPV device is installed on a table, and the DPV device comprises:
an upper duct and a lower duct, disposed on two opposite sides of a tabletop respectively;
an air supply panel, disposed on an outlet of the upper duct;
a duct fan, disposed in the lower duct and closer to the ground in the room relative to the upper duct, wherein an air supply volume of the duct fan is adjustable, and the duct fan is configured to send air absorbed from a ground air lake to a user's face area through the air supply panel of the upper duct;
a flexible duct, directly connected between the air supply panel and the outlet of the upper duct, wherein the flexible duct is adjustable relative to the upper duct and configured to adjust an air supply angle of the air supply panel; and
a filter layer, disposed in the lower duct and located at a side of the duct fan facing away from the ground, wherein the filter layer comprises activated carbon, which is configured to absorb odors of the air sent from the duct fan.
