Title:
車両用冷却装置及びこれを用いた冷却方法
Document Type and Number:
Japanese Patent JP7271470
Kind Code:
B2
Abstract:
To enable cooling in a passenger compartment without using an expensive electronic expansion device and enable only a battery to be cooled in a vehicular cooling device which can cool the battery and a front seat space and a rear seat space in the passenger compartment.SOLUTION: A first branch point (B1), at which a duct line leading to a battery evaporator 11 which cools a battery 13 is branched, and a second branch point (B2), at which a duct line leading to a front seat evaporator 21 which cools a front seat space and a duct line leading to a rear seat evaporator 31 which cools a rear seat space are branched, are provided at a refrigerant duct line at the downstream side of a radiator 3 which radiates heat from a refrigerant compressed by a compressor 2. A first confluence point (J1), at which a duct line of the refrigerant flowing out from the battery evaporator 11 is joined, and a second confluence point (J2), at which a duct line of the refrigerant flowing out from the front seat evaporator 21 and a duct line of the refrigerant flowing out from the rear seat evaporator 31 are joined, are provided at the refrigerant duct line at the upstream side of the compressor 2. An on-off valve 5 is disposed in a refrigerant duct line 101b between the first branch point (B1) and the second branch point (B2).SELECTED DRAWING: Figure 1
