Mobile cooling device for maintaining e.g. food stuff at constant and cold temperature in catering industry, has return duct returning heat transfer liquid to main reservoir after cooling end containers

摘要

The device (10) has a main reservoir (12) containing a heat transfer liquid (14) e.g. glycol water, and a cooling unit for cooling the heat transfer liquid. End containers (18) have content that is cooled by exchanging heat with the cooled heat transfer liquid passed through a wall of the end containers. A heat transfer liquid transporting duct (16) transports the heat transfer liquid to the end containers. A return duct (30) returns the heat transfer liquid to the main reservoir after cooling the end containers.
