摘要： A vehicle air-conditioning device includes: a first coolant-water circulation path in which coolant water passes through an engine ; a second coolant-water circulation path that is communicated with the first coolant-water circulation path and in which the coolant water passes through a vehicle-cabin radiator; a shutting off mechanism that shuts off, when switched to a shut-off state, the communication between the first coolant-water circulation path and the second coolant-water circulation path; and a refrigeration cycle. The refrigeration cycle has: a compressor for compressing cooling medium; a secondary evaporator in which the cooling medium absorbs heat from the coolant water in the first coolant-water circulation path; a secondary condenser that releases heat of the cooling medium that has absorbed the heat at the secondary evaporator to the coolant water in the second coolant-water circulation path; and a secondary expander that decompresses the cooling medium that has passed through the secondary condenser.
