COMPOSITE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/223770
Kind Code:
A1
Abstract:
[Problem] To provide a composite device that contributes to downsizing of vehicular air-conditioning devices and the like and can also minimize occurrence of troubles due to a liquefied refrigerant during activation of a refrigerant compressing function. [Solution] A composite device 1 has a refrigerant compressing function and a heat-medium heating function and comprises: a first housing 2A in which a compression mechanism 3 for compressing a refrigerant and an electric motor 4 for driving said compression mechanism 3 are accommodated in series; a second housing 2B in which an electric heater 5 for heating a heat medium is accommodated; and a third housing 2C in which a motor drive circuit 20 and a heater control circuit 30 are accommodated. The first housing 2A, the second housing 2B, and the third housing 2C are constantly combined with each other. The first housing 2A and the second housing 2B are arranged side by side such that the electric heater 5 within the second housing 2B can heat the refrigerant that is within the first housing 2A and is compressed by the compression mechanism 3.
