Claim Text:
1. An air-conditioning system for a vehicle comprising: a switching heat exchanger disposed at a front portion of the vehicle and including a heat exchanger core, a receiver tank, and a switch valve, the heat exchanger core having a primary region and a secondary region, the primary region being before the secondary region, the heat exchanger core exchanging heat between refrigerant flowing therein and air blowing through, an inlet of the receiver tank communicating with the primary region of the heat exchanger core for receiving the refrigerant and an outlet of the receiver tank communicating with the secondary region for providing the refrigerant to the heat exchanger core, the switch valve being arranged between the heat exchanger core and the receiver tank for controlling the flow of the refrigerant from the heat exchanger core to the receiver tank; and a controller configured to control the switch valve to an access position during a cooling mode and a bypass position during a heating mode, wherein in the access position, the switch valve opens a first passage to have the primary region of the heat exchanger core communicating with the receiver tank and the refrigerant flows from the primary region to the receiver tank, from which the refrigerant flows to the secondary region before flowing out from an outlet of the heat exchanger core, and in the bypass position, the switch valve opens a second passage to have the primary region of the heat exchanger core communicate with the outlet of the heat exchanger core and the refrigerant flows from the primary region to the outlet of the heat exchanger core.
