Abstract

Um bei einer Kälteanlage mit Rückgewinnung der Verflüs­ sigungswärme einer Minderung der Kälteleistung beim Um­ schalten von reinem Kälteerzeugungsbetrieb auf gleich­ zeitigen Kälteerzeugungs- und Wärmerückgewinnungsbetrieb zu begegnen, wird das anfallende Kältemittelkondensat vor seiner Zufuhr zum Entspannungsorgan (18) unterkühlt. Hierzu wird ein zweiter Wärmetauscher (16) eingesetzt, der einem als Verflüssiger dienenden ersten Wärmetau­ scher (14) kältemittelseitig nachgeschaltet ist. Die wirksame Wärmetauschfläche des zweiten Wärmetauschers (16) wird hierbei durch Anstau von Kältemittelkondensat in Abhängigkeit vom Temperaturniveau der rückgewonnenen Verflüssigungswärme an den jeweiligen Betriebszustand angepaßt, wodurch gleichzeitig eine einfache Regelung dieses Temperaturniveaus erreicht wird. To in a refrigeration system with recovery of the condensate heat of reduction of the cooling capacity when moving switch from pure refrigeration mode to the same early refrigeration and heat recovery operations to counteract the resulting refrigerant condensate supercooled before it is supplied to the relaxation organ (18). For this purpose, a second heat exchanger (16) is used, the first heat rope serving as a condenser shear (14) is connected on the refrigerant side. The effective heat exchange surface of the second heat exchanger (16) is caused by the accumulation of refrigerant condensate depending on the temperature level of the recovered Liquefaction heat to the respective operating state adapted, which at the same time makes simple regulation this temperature level is reached.
