Abstract

The invention relates to a system for cooling and heating, having a first heat exchanger (10) for outputting heat to and extracting it from a heat reservoir (12); a second heat exchanger (14) for extracting heat from and outputting it into a space (16) to be cooled or heated; a compressor (18); an expansion device (20); and means (22, 24) for switchover between a cooling mode and a heating mode; wherein the switchover means (22, 24) are integrated with a module (26). The invention also relates to a method for switching over between a cooling mode and a heating mode.
