摘要： In zwei Zonen (2 und 3,4) wird eine primäre und eine sekundäre Eiskristallsuspension am Tripelpunkt erzeugt. Die primäre Eiserzeugung erfolgt durch Kondensation eines verdichteten Dampfgemisches, bestehend aus Wasser und Aethanol bei seinem Tripelpunkt. Hierbei entsteht ein heterogenes Gemisch aus Eispartikeln und wässriger Aethanollösung. Aus der anschliessend erfolgenden Erzeugung einer Eiskristallsuspension wird Aethanol mittels Wasser ausgewaschen und aus der gereinigten Eiskristallsuspension durch Gefrierverdampfung die sekundäre Eiskristallsuspension gewonnen, die das Produkt bildet.
Dieses Verfahren ermöglicht eine kontinuierliche Kristalleiserzeugung. Da eine reduzierte Kompressionsleistung für die Verdichtung des bei der Gefrierverdampfung auftretenden Dampfes benötigt wird, wird in einer Ausführungsform eines Eiserzeugungsapparates (1) ein Dampfstrahlverdichter (8, 9,10,11,12) verwendet.
摘要翻译：为两个区域（2和3.4）的初级和次级的冰晶悬浮液在三相点被产生。主制冰通过在其三相点由水和乙醇的压缩蒸气混合物的缩合进行。这引起了冰粒和乙醇水溶液的异质混合物。从此发生产生的乙醇的冰晶悬浮液通过水洗出并通过冷冻干燥，形成产物中回收从纯化的冰晶悬浮液的次要的冰晶悬浮液。此方法允许连续Kristalleiserzeugung。由于需要用于压缩在冷冻干燥中产生的蒸汽的减小的压缩动力，蒸汽喷气压缩机（8，9,10,11,12）在Eiserzeugungsapparates（1）的一个实施例被使用。

摘要： The invention is a snow gun (1) for the production of artificial snow (N), comprising an inlet mouth (3) and an outlet mouth (4) for the artificial snow (N). The gun furthermore comprises: an evaporation chamber (5), in such a way as to implement a process of evaporation of a portion of a liquid substance (S) in its triple point and substantially in vacuum conditions, obtaining steam (V); a condensation chamber (9) communicating with the evaporation chamber (5) through the interposition of compression means (8) suited to draw the steam (V) from the evaporation chamber (5), the condensation chamber (9) causing the condensation of the steam (V) that is compressed by the compression means (8); a crystallization tank (11) connected to the evaporation chamber (5) so as to transfer the remaining non-evaporated mixture (M) of the liquid substance (S) in the crystallization tank (11), in such a way as to implement a process of growth of the portion in the crystallization phase (C) in order to obtain the artificial snow (N); and finally a collection unit (17) suited to collect the artificial snow (N) and distribute it in the external environment.

摘要： The invention relates to an apparatus and a method of freezing a liquid substance contained in a receptacle (1,2,3,4,5,6,8), comprising the steps of: providing the liquid substance in the receptacle, providing a cooling chamber (20) and a cooling device (12) having a cooling surface (7); setting the temperature of the cooling surface (7) to less than -130°C, starting a freezing procedure by placing the receptacle on the cooling surface to make surface contact between the receptacle and the cooling surface to cool the receptacle and thereby to have a portion of the liquid substance, which is contained in the receptacle in proximity of the cooling surface, form a seed or initial zone of nucleation; and continuing the freezing procedure to completely freeze the substance such that, starting from the seed or initial zone of nucleation, directional freezing of the liquid substance with a propagating crystallisation front occurs at or near melting point temperature of the substance at the crystallisation front. The step of continuing the freezing procedure includes transferring the receptacle from the cooling surface to a region of the cooling chamber before or after the liquid substance contained in the receptacle has been completely frozen, with the cooling temperature within said region of the cooling chamber being set to a value in the range between -60°C and -5°C.

摘要： Method and equipment for the utilization of the freezing heat contained in water as a source of heat of a heat pump. The water flow to be utilized as the source of heat is evaporated in one or several stages (4) at such a low pressure that, when the vapour that is formed binds its evaporation heat out of the water, part of the water freezes. The vapour formed is condensed in one or several heat exchangers functioning as the evaporator of the heat pump, whereat the vapour, on being condensed, delivers its heat to the heat transfer medium used in the heat pump.

摘要： De la glace en vrac est produite en grande quantite en injectant de l'eau dans une chambre sous vide (2), dans laquelle de la glace ou de la neige sont produites par l'evaporation instantanee de l'eau. La glace en vrac est evacuee de la chambre sous vide (2) et le volume ou l'ecoulement important de vapeur a basse pression est extrait au moyen d'un compresseur centrifuge simple a etage unique (16) qui envoie la vapeur legerement comprimee a un condenseur exterieur refrigere positivement (22) et fonctionnant a une temperature de condensation legerement superieure a 0 C, la pression de condensation de la vapeur etant suffisamment basse pour conditionner ou permettre l'utilisation d'un compresseur (16) d'une tres grande simplicite, tandis que d'autre part la temperature de condensation est tout juste suffisante pour eviter des problemes de congelation dans le condenseur (22). Le systeme de refrigeration auxiliaire necessaire (24, 26, 28) peut etre un systeme simple et courant de rendement eleve a cause de la temperature relativement haute de l'evaporateur, et le compresseur de vapeur (16) egalement peut etre une unite simple, etant donne qu'il traite la vapeur uniquement a l'extremite inferieure de la plage de pression et de densite de celle-ci. Le condenseur (26) du systeme de refrigeration auxiliaire peut etre utilise en tant que radiateur efficace pour un systeme de chauffage exterieur.
