Abstract

An electronic expansion valve (80) is closed when a heating-pump device is inactive. It regulates overheating in an injected coolant when hot-gas temperatures are below a critical temperature. When hot-gas temperatures are in a range of a critical temperature, a partly liquid coolant is injected into a condenser (10) so that a defined maximum value is not reached in a hot-gas temperature. An independent claim is also included for a method for operating a heating-pump device.
