VEHICLE HEAT MANAGEMENT DEVICE

摘要

A vehicle heat management device applied to a refrigeration cycle includes a pump that suctions and discharges a heat medium, a heat medium cooler that exchanges heat between the heat medium discharged by the pump and low-pressure side refrigerant in the refrigeration cycle to evaporate the low-pressure side refrigerant and to cool the heat medium, a heat medium circulation device through which the heat medium whose heat is exchanged in the heat medium cooler flows and in which the heat medium absorbs heat by its sensible heat change, and a heat medium flow control part that increases a flow rate of the heat medium flowing through the heat medium circulation device when an amount of the heat absorbed by the heat medium in the heat medium circulation device is determined to be larger than a predetermined amount of heat.

1. A vehicle heat management device applied to a refrigeration cycle, comprising:
a pump that suctions and discharges a heat medium; a heat medium cooler that exchanges heat between the heat medium discharged by the pump and low-pressure side refrigerant in the refrigeration cycle to evaporate the low-pressure side refrigerant and to cool the heat medium; a heat medium circulation device, wherein:
the heat medium, the heat of which is exchanged in the heat medium cooler flows through the heat medium circulation device; andthe heat medium absorbs heat by its sensible heat change in the heat medium circulation device; and a heat medium flow control part that increases a flow rate of the heat medium flowing through the heat medium circulation device when an amount of the heat absorbed by the heat medium in the heat medium circulation device is determined to be larger than a predetermined amount of heat.
