Abstract
【解決手段】炭化水素(HC)冷媒用、特にプロパン(R−290)用に設計された冷凍システムを有する製氷機は、2つの独立した冷凍システムと特別な蒸発機構とを含み、蒸発機構は2つの冷却回路に取り付けられた単一の冷凍板を備える。蛇行構造は有利なパターンに設計され、冷凍時に氷のブリッジングの均一を保持すること、および、均一の熱負荷分配の提供により獲得時の好ましくない溶解を最小化することによって効率を高める。そうすると、大容量の製氷機において可燃性の冷媒が単一の回路に充填されことから起こりうる、可燃性の冷媒に課する充填量制限は回避される。製氷機は単一の水回路と制御システムとを含み、適切で効率的な氷製造を保持する。
