Abstract: An air conditioning device for a vehicle includes: a housing having an inside divided into an inflow space, a heat exchange space, and an outflow space, which are straightly arranged, and having a plurality of discharge ports, which communicates with an interior, at the inflow space; a blowing unit disposed at the inflow space of the housing and configured to blow air; a heat exchange unit disposed at the heat exchange space of the housing and configured to adjust a temperature of conditioned air by exchanging heat with air; and an opening-closing door disposed at the outflow space of the housing and configured to open and close the plurality of discharge ports such that conditioned air at an adjusted temperature selectively flows to the plurality of discharge ports. The air conditioning device adjusts the temperature of conditioned air for respective modes and reduces a flow resistance of air.

Abstract: A method for routing test comprises the steps of: checking a test mode of the routing test by receiving the test mode by a user; recalling a stored virtual network or editing the virtual network, when the routing test is performed by using a virtual network defined by the user; generating new virtual networks recursively based on respective information, when the routing test is performed by using a virtual network generated by a virtual network generator included in a routing test system; operating a target protocol of a virtual router and a router under test of the virtual network; and transmitting a packet considering a portion of the virtual network as a destination address trough the router under test, and monitoring links of the router under test. A routing test system according to the present invention generates various network topologies as much as user wants through a network generator, and performs a routing test after transmitting information to make a target router verify the generated topologies.
