Abstract

Verfahren und Vorrichtung zum Kühlen eines Raumes (3) mit Hilfe von Kohlendioxyd-Trockeneis. Es werden zwei unterschiedliche Kühlbetriebsarten mit unterschiedlichen Kühlleistungen angewendet, d. h. eine Kühlung geringerer Leistung als die erforderliche Kühlleistung als Grundküh­ lung und eine ergänzende Kühlung, die bedarfsweise ein­ geschaltet wird. Das für beide Kühlungsarten verwendete Trockeneis befindet sich in einem geschlossenen Behälter (1), der in einem mit einer Wärmeisolierung versehenen Kasten (2) angeordnet ist, wobei zwischen dem geschlosse­ nen Behälter (1) und der Innenwand des Kastens (2) eine mit dem Kühlraum (3) verbundene Luftführung (4) ausgebildet ist, die an einen in den Kühlraum (3) mündenden Luftkanal (5) angeschlossen ist. Das im Wärmeaustausch mit der Luft in der Luftführung (4) verdampfte Kohlendioxyd wird aus dem Behälter (1) für die Grundkühlung über ein von einem Thermostaten (11) gesteuertes Absperrorgan (10) unmittel­ bar in den Kühlraum (3) eingeführt und/oder über ein ande­ res Absperrorgan (8) und eine Düse in die Luftführung (4) oder den Luftkanal (5) eingeblasen, wodurch in der Luftfüh­ rung eine Strömung erzeugt wird, durch welche die Ver­ dampfung des Trockeneises in dem Behälter (1) gesteigert wird. Method and device for cooling a room (3) with the help of carbon dioxide dry ice. There will be two different cooling modes with different Cooling capacities applied, d. H. cooling less Output as the required cooling output as basic cooling and additional cooling, which if necessary is switched. The one used for both types of cooling Dry ice is in a closed container (1) in a heat-insulated Box (2) is arranged, being between the closed NEN container (1) and the inner wall of the box (2) with one air duct (4) connected to the cooling space (3) is to an air duct opening into the cooling space (3) (5) is connected. That in the heat exchange with the air evaporated carbon dioxide in the air duct (4) the container (1) for basic cooling via one of one Thermostats (11) controlled shut-off device (10) immediately bar introduced into the refrigerator (3) and / or via another Res shut-off device (8) and a nozzle in the air duct (4) or blown in the air duct (5), whereby in the air guide a flow is generated through which the Ver Evaporation of the dry ice in the container (1) increased becomes.
