Abstract
Description
本出願は、2019年11月18日に出願されたイタリアの特許出願番号102019000021486の優先権を主張し、その開示全体が参照により本明細書に組み込まれる。
本発明は、特に、空調、食品貯蔵、プロセス冷却機、および媒体の温度および/または湿度を管理することを目的とした他の機械のための、空冷式冷凍サイクル構成に関する。
・圧縮手段によるポイント2a=5bと2bとの間の圧縮。圧縮手段2による仕事Wにより気体冷媒流体がより高圧の過熱状態に移行する。
・凝縮器6によるポイント2bおよび6bの間の一定圧力(圧力損失を除く)の熱交換。冷媒流体は過熱蒸気から飽和液体に移行し、周囲空気に熱Q1’を提供する。
・サブクーラー7によるポイント6bおよびポイント7bの間のさらなる熱交換。凝縮された流体は、その温度を低下させ続け、周囲空気に熱Q1”を提供する。
・ポイント7bおよび4bの間の等エンタルピー膨張。凝縮された流体は、現在の温度に達するまでその圧力を低下させる。
・ポイント4bおよびポイント2aの間の一定温度の熱交換(圧力損失を除く)。流体が蒸発し、過熱して気相に移行し、それによって媒体から熱Q2が抽出される。
