Abstract

This invention relates to a cooling device (1) wherein it is accomplished that the life-span of the compressor (4) is increased and thus the refrigeration cycle is performed in a more effective manner as oil accumulated in the refrigeration cycle is regained by the compressor by performing an oil return procedure.
