摘要： An air conditioning device (1000) has: a refrigerant circuit (100) that is formed of a compressor (1), a switching valve (2), a cascade heat exchanger (3), an expansion valve (4) and an outdoor heat exchanger (5) connected to one another by a first pipe (21) through which a refrigerant flows, and capable of performing a defrosting operation in which the refrigerant discharged from the compressor (1) is introduced into the outdoor heat exchanger (5); a heat-transfer medium circuit (200) that is formed of a pump (12), the cascade heat exchanger (3), and the indoor heat exchanger (11) connected to one another by a second pipe (23) through which a heat-transfer medium flows; and a control device (31) that controls the compressor (1) and the pump (12). When an amount of heat storage of the heat-transfer medium is less than a threshold, the control device (31) reduces the heating capability of the indoor heat exchanger (11) when the air conditioning device (1000) transitions from a heating operation to the defrosting operation.

摘要： Provided is a heat exchanger and an air conditioner each of which has a surface structure that can reduce adherence of frost by scattering condensed water even when used in a frosting environment. A heat exchanger includes a portion on whose surface a water-repellent coating is formed. The surface on which the water-repellent coating is formed has a surface structure that satisfies all of the following relationships: rw(entirety) > 0.6/|cosθw|, rw(protrusion) > 0.6/|cosθw|, 0.1

摘要： Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Verhindern einer Vereisung in einer Auffangwanne (1) für Wasser (2), welches von einem von Umgebungsluft (9) durchströmbaren Wärmetauscher (3) einer Wärmepumpenanlage (4) abtropft, wobei in der Auffangwanne (1) Wasser (2) bis zu einer vorgebbaren Höhe (H) angestaut und danach durch einen Überlauf (5) und/oder Abfluss (6) abgeführt wird und wobei der Auffangwanne (1) und/oder dem angestauten Wasser (2) bei Gefahr des Einfrierens so viel Wärme zugeführt wird, dass das angestaute Wasser (2) eine vorgebbare Mindesttemperatur nicht unterschreitet. Dazu weist die Auffangwanne (1) insbesondere einen mit einem Überlauf (5) verbundenen Abfluss (6) auf, und der Überlauf (5) ist so hoch und so angeordnet, dass sich in der Auffangwanne (1) Wasser (2) mit einer zusammenhängenden Wasseroberfläche (7) anstaut, bevor Wasser (2) durch den Überlauf (5) abfließt und wobei in oder an der Auffangwanne (1) mindestens eine Heizeinrichtung (11; 12) angeordnet ist, durch die bei Gefahr des Einfrierens Wärme zuführbar ist. Die vorliegende Erfindung erlaubt es, mit geringem Einsatz von Energie und auch bei großen Toleranzen bei der Form und Aufstellung einer Auffangwanne (1) eine Vereisung zu verhindern.
