Refrigeration circuit device, particularly motor vehicle refrigeration circuit device, has operating-medium circuit, which is provided to guide operating unit partially by motor unit

摘要

The refrigeration circuit device (10) has an operating-medium circuit (11), which is provided to guide an operating unit partially by a motor unit (12). A temperature sensor (13) is provided to detect an operating fluid temperature in the operating medium circuit. Another temperature sensor (14) is provided for parallel detection of operating medium temperature in the operating-medium circuit. An independent claim is also included for a method for detecting fault or recognizing heating by temperature sensors in refrigeration circuit device.
