Title:
VEHICULAR AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/056806
Kind Code:
A1
Abstract:
[Problem] To improve comfort, without the addition of a water temperature detection sensor for detecting the temperature of cooling water, of an on-board air-conditioning device equipped with settings for switching the flow of engine cooling water. [Solution] A vehicular air-conditioning device is equipped with: a blower (16) for sending air into a cabin; a heater core (55) disposed on a circulation path through which cooling water for an internal combustion engine (50) circulates; a bypass path (56) for causing the cooling water to circulate by bypassing the heater core; a changeover device (54) for switching between a first mode in which the cooling water flows through the bypass path while bypassing the heater core before returning to the internal combustion engine and a second mode in which the cooling water flows through the heater core; a water temperature sensor (53) for detecting the temperature of the cooling water at a position where the cooling water flows in both the first and second modes; a control section (S104) for controlling the operation of the blower on the basis of control water-temperature data; and first and second water temperature data calculation sections for calculating the control water-temperature data in the first and second modes. The first water temperature data calculation section calculates the water-temperature data on the basis of the cooling water temperature detected at the time of starting the internal combustion engine, and the second water temperature data calculation section sets a lower temperature than the detected cooling water temperature as the control water-temperature data.
