Title:
VEHICULAR TEMPERATURE REGULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/056856
Kind Code:
A1
Abstract:
[Problem] To suppress suction of a liquid refrigerant into a compressor of a refrigeration cycle where a chiller is possibly filled with the liquid refrigerant. [Solution] A vehicular temperature adjustment device (10) is provided with a refrigeration cycle (11) through which a refrigerant circulates, a high-temperature cycle (20) through which a heat medium circulates, and a low-temperature cycle (30) through which the heat medium circulates. The refrigeration cycle includes a heating heat exchanger (12) for heating the heat medium by means of heat exchange between the refrigerant discharged from a compressor (15) and the heat medium in the high-temperature cycle, and a cooling heat exchanger (13) for cooling the heat medium by means of heat exchange between the refrigerant decompressed and expanded by a pressure reduction unit (16) and the heat medium in the low-temperature cycle. The vehicular temperature adjustment device includes connection sections (41, 42) for connecting the high-temperature cycle with the low-temperature cycle, regulation parts (61, 62, 63, 91a, 92a, 93a, 94a) provided on the connection sections for regulating the flow of the heat medium, and a control unit (14). The control unit (14) controls the regulation parts, a first pump, and a second pump such that the heat medium in the low-temperature cycle is switched with the heat medium in the high-temperature cycle after the compressor is stopped, or after a stop command for stopping the compressor is given.
