Cooling device for maintaining temperature of areas with air duct has closing means in the form of shut-off valves, which are attached to air duct and air way and can be operated to permit or prevent flow through air duct and air way

摘要

Cooling device has an air way (7), parallel to air duct (1), having an upper inlet end (8) and lower outlet end (9). Air duct and air way are attached at the inlet side of cooling air outlet of air cooler (11). Closing means (5,10), particularly in the form of shut-off valves, are attached to air duct and air way, which can be operated to permit or prevent the flow through air duct and air way alternatively.
