REFRIGERATION CYCLE DEVICE

Title:

REFRIGERATION CYCLE DEVICE

Document Type and Number:

Japanese Patent JP2014126209

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To prevent an accumulator accumulating refrigerant from being made large in size in a refrigeration cycle device making temperature adjustments of a plurality of types of temperature adjustment targets.SOLUTION: A refrigeration cycle device includes an accumulator 24 that accumulates refrigerant discharged from an auxiliary heat exchanger 22, and that absorbs a fluctuation in a necessary refrigerant amount, the auxiliary heat exchanger 22 evaporating refrigerant output from an indoor evaporator 20 that evaporates one refrigerant diverged by a downstream diverging portion 13d and cooling indoor blown air and the other refrigerant diverged by the downstream diverging portion 13d, and cooling air blown for battery. A battery expansion valve 21 with a function to be fully closed is arranged at a position of an inflow-side pipe 23, which connects the downstream diverging portion 13d to the auxiliary heat exchanger 22, closer to an inlet of the auxiliary heat exchanger 22 than the downstream diverging portion 13d. By doing so, when the battery expansion valve 21 is fully closed and a refrigerant channel is switched, surplus refrigerant can be accumulated in the inflow-side pipe 23 in a range from the downstream diverging portion 13d to the auxiliary heat exchanger 22.
