本发明所述的设置有制冰机的风直冷结合多温控冰箱工作方式和 各部件组成如下:
本发明所述的冰箱冰块冷冻室 1 和冷藏室 2, 在冷冻室 1 中, 设 置一个制冰室, 所述的制冰室安装有制冰室门 9, 可以起到隔绝冷量 流动和串味的作用; 将制冰机固定在制冰室中, 在所述的制冰机下设 置储冰盒; 冷藏室采用直冷方式, 冷冻室也采用直冷方式, 在冷冻室 的蒸发器空间再设置一进风口 7和一出风口 6通向制冰室, 需要时利 用风冷的方式对制冰室进行深度冷却。
在制冰室的出风口 6和 /或进风口 7上可以安装一可以转动开闭的 门, 在制冰室作为常用的冷冻室空间时, 关闭所述的门, 这样, 冷冻 室也是采用的直冷的方式进行冷冻, 如果将制冰室改为深冷冻室, 即, 在所述的制冰室 3 中不设置制冰机, 实际上, 所述的冰箱便构成了双 蒸发器三温三控的风直冷结合冰箱, SP, 可以独立的根据需要控制冷 藏室、 冷冻室和制冰室的冷量。
在本发明所述的冰箱的冷藏室的直冷采用平板式蒸发器, 由于平 板板蒸发器靠压粘合工艺贴附于冷藏室内胆后壁上部, 通过自然对流 制冷, 其间室内温度达到设定温度后, 冷藏温控器向脉冲电磁阀发出 脉冲信号, 脉冲电磁阀动作, 切断制冷剂的冷藏制冷循环。
所述的平板式蒸发器, 因为贴附在冷藏内胆里面, 其具有蒸发器 隐藏、 不影响外观、 制冷均匀、 不宜造成物品冻伤等特点。
冷藏室釆用平板式蒸发器, 在一定程度上保持了冷藏室的湿度。 参见图 1, 图 1 (b)是本发明所述设置有制冰机的风直冷结合多温 控冰箱的剖视图,从该图中可以清楚地了解各部件的位置和连接方式。
在本发明所述的冰箱中, 冷冻室釆用的也是直冷方式, 蒸发器的 一面也紧贴在冷冻室内胆里面, 但是, 其另一面后形成一个间隙, 来 自制冰室的空气流经其上, 经再度冷却后进入制冰室, 制冰室釆用风 冷的制冷方式, 使得制冰制冰室的冷冻速度明显高于单纯使用直冷方 式的冷冻速度。
因此, 制冰室采用风直冷混合制冰模式, 相当于在冷冻室形成二 个可控的温区。
由于在冷冻室釆用风直冷混合方式制冷, 为了提高制冰室的制冷 效率, 冷冻室的蒸发器采用了翅片式蒸发器, 为了防止翅片式蒸发器 相对冷冻室供应的冷量不足, 制冰室的全部或者一部分采用导热性好 的材料作为隔板, 例如, 金属铝, 这样, 制冰室的冷量可以通过隔板 进行热交换, 又由于制冰室优选设置在冷冻室的上方, 因此, 制冰室 外壁的冷空气下降, 从而形成了有一个热交换的循环。
本发明所述的多温控是指根据冷藏或冷冻对制冷量的需求, 制冷 剂通过脉冲电磁阀流向冷藏室或冷冻室, 两室的温度分别被各室内的 温控器感温头感知病由冰箱的控制器控制在制冰室设置动作传感器, 或者将制冰室的电路和冰箱的总控电路连接, 以感知制冰机的工作情 况。 判断制冰是否进行, 如果制冰开始, 启动冷冻室蒸发器, 并开启 风扇使制冰室迅速达到制冰速冻温度;
判断制冰室处于温度维持状态, 如果温度未达到指定的制冰维持 温度, 启动冷冻室蒸发器, 并开启风扇使制冰室迅速达到制冰维持温 度;
由于制冰室的指定温度和维持温度低于冷冻室指定温度, 因此, 在所述情况下, 冷冻室的温度应该一直维持在冷冻室指定温度以下。
优选釆用制冰室维持温度等于冷冻室指定温度, 当冷冻室温度未 达到指定温度, 冷冻室需要冷量, 制冷剂走主回路, 由于冷藏室的主 蒸发器面积较小, 因此, 冷藏蒸发器释放的冷量少, 冷藏室温度的下 降非常小; 当采用金属隔板的制冰室时, 冷冻室和制冰室的热量充分 交换。
为了提高制冰室的制冰效率, 即, 尽可能使制冰室维持一个比冷 冻室更加地的温度, 制冰室和冷冻室之间采用绝热性好的搁板, 并且 使得制冰室速冻温度和维持温度都明显低于冷冻室指定温度, 在此情 况下, 制冰室在不放置制冰机的情形下, 形成了一个深冷冻室。
当冷冻室达到指定温度, 而冷藏室未到达指定温度, 开启旁通回 路, 主回路的面积较小的冷藏室主蒸发器和一个面积较大的冷藏室附 加蒸发器结合成面积很大的冷藏室蒸发器, 迅速地调节冷藏室温度。 制冷系统。
本发明所述的冰箱包括压缩机、 冷凝器、 干燥过滤器、 毛细管、 冷冻蒸发器、 冷冻室、 冷藏蒸发器。 冷藏室、 吸气管。
在本发明中, 冷藏室采用的是平板式蒸发器, 冷冻室釆用的是翅 片式蒸发器。 '
接下来我们看制冷系统的方式, 现有技术已经公开了蒸发器并列 结构 (分立双循环结构) 或在传统的蒸发器的串连结构中加入一个辅 助回路, 这二种结构, 冷冻室和冷藏室基本可以分别控制, 但仍然存 在热力学不可逆损失很大、 吸气管外表结露等缺点。
本发明提出在旁通双循环冰箱的旁通回路中再接入一个面积较大 的蒸发器作为冷藏室附加蒸发器, 因此冷藏室的蒸发器面积很大, 旁 通毛细管可以设计的较短, 因为即使流量很大, 但由于冷藏蒸发器面 积大, 制冷剂在蒸发器中将全部蒸发, 基本无液体制冷剂吸入吸气管; 当冷藏室不需要冷量, 而冷冻室需要冷量, 制冷剂走主回路, 由于原 冷藏室的蒸发器面积较小, 因此, 冷藏蒸发器释放的冷量少, 冷藏室 温度的下降非常小。
因此, 冷藏室的冷量大部分来自旁通回路, 由于旁通回路中旁通 毛细管较短, 蒸发温度高, 热力学不可逆损失小, 系统的 COP高。
本发明所述的双循环冰箱, 包括压缩机 1 1、 冷凝器 12、 干燥过滤 器 13、 三通电磁阀 14、 主毛细管 15、 旁通毛细管 16、 冷冻蒸发器 17、 原冷藏蒸发器 19、 储液器 20, 在所述的旁通循环回路还包括一个附加 冷藏蒸发器 18, 压缩机 1 1出口与冷凝器 12进口连接, 冷凝器 12出口与 干燥过滤器 13进口连接,干燥过滤器 13出口与三通电磁阀 13入口连接, 三通电磁阀 14的一个出口与主毛细管 15进口连接, 另一个出口与旁通 毛细管 16进口连接, 主毛细管 15出口与冷冻蒸发器 17进口连接, 旁通 毛细管 16出口与附加冷藏蒸发器 18进口连接, 冷冻蒸发器 17出口及附 加冷藏蒸发器 18出口都与原冷藏蒸发器 19进口连接, 原冷藏蒸发器 19 出口与储液器 20进口连接, 储液器 20出口与吸气管一端连接, 吸气管 的另一端与压缩机 1 1入口连接。 '
本发明所述的制冷系统与单循环系统相比具有以下优势: 可以避免了环境温度对冷藏冷冻室内温度的影响, 实现了能量的 最佳分配和利用;
由于双循环制冷系统可以独立地控制冷藏室和冷冻室温度, 所以 其冷冻能力远远大于普通单循环制冷系统冰箱, 双循环冰箱在冷冻过 程中冷藏冷冻室内温度波动范围远远小于单循环冰箱, 较小的温度波 动将有利于食品的贮存保鲜。
对于双循环制冷系统, 在设计时可以选择较大的冷藏室蒸发器, 这样很容易使冰箱满足髙温条件要求,而在低环境温度时,只要冷藏室 设定温度低于环境温度, 冰箱在没有任何加热补偿条件下可以完全正 常运行。
本发明所述的冰箱, 提出了一种冷藏蒸发面积可变的旁通双循环 冰箱, 研究人员认为, 影响冷藏蒸发面积可变的旁通双循环冰箱节能 的因素,主要为冷藏室负荷、 旁通回路负荷及主循环、 旁通循环的系统 COP等因素与节能效果的函数关系, 应用该函数关系,在目前冰箱的实 际工况下,本发明所述的冰箱比蒸发器串联单循环冰箱节能 12%左右。
本发明所述的冰箱中的压缩机为蒸汽压缩式压缩机, 主要包括压 缩机 1 1, 冷凝器 12, 毛细管 15、 16, 干燥过滤器 13 , 三通电磁阀 14, 和蒸发器 17、 18、 19, 所述的蒸汽压缩式制冷循环, 经过压缩、 冷凝、 节流、 蒸发四个过程不断循环, 制冷剂周期性的发生从蒸汽变为液体, 从液体变为蒸汽的状态变化,不断地把冰箱内的热量转移到冰箱外部, 从而达到制冷目的。
在本发明所述的冰箱中, 釆用的制冷剂为 R134a, 在本发明的非最 优选的实施例中, 也可以采用现有技术中其他公知的制冷剂;
本发明的研究人员在设计本发明所述的冰箱时, 针对制冷系统的 配置、 蒸发器的配置、 蒸发器的简体参数的配置进行了详细的研究, 并得出最终的设计结论, 由于本发明对现有技术的配置, 使得本发明 所述的冰箱的噪音降低、 热效率提高, 具体如下- 首先, 现有技术表明, 平板式 (直冷式) 蒸发器是由其表面低温 的自然对流而降低冰箱内的温度, 其优点是湿度适宜、 保鲜性能好、 省电、 相同体积下有效容积大; 而翅片式蒸发器 (风冷式) 是由冷气 由风道强制吹入箱内空间造成循环, 优点是自动除霜、 温度均匀、 缺 点是冷冻室湿度低、 食物易风干脱水, 耗电高, 有效容积低。
本发明所述冰箱的特点是冷冻和冷藏都釆用直冷, 冷冻室的直冷 采用翅片式蒸发器, 冷冻室冷量的缺失采用制冰室隔板的传热进行弥 补, 而制冰室釆用风冷的方式, 正如前述, 采用风冷的制冰室的冷量, 也可以通过所述搁板传导对冷冻室进行冷冻。
针对本发明的特点, 常规的翅片式蒸发器被用来在冷冻室中进行 直冷就会产生一定的问题, 本发明的研究人员对翅片式蒸发器进行了 进一步的研究表明, 翅片式蒸发器的效率受到多种因素的影响, 参见 图 2 (a)至图 2 (f)。
结论是空气相对湿度对翅片式蒸发器的性能影响较大, 尤其是高 湿度的情形下, 随着蒸发器运行时间的延长, 蒸发器效率 ( η。) 和空 气侧平均换热系数 (Κ。) 急剧下降, 因此, 控制空气相对湿度对蒸发 器有重要影响。 另外, 翅片间距对蒸发器的性能影响也很大, 宽间距翅片蒸发器 换热性能明显由于密间距翅片蒸发器, 在翅片间距约 4mm时, 蒸发器 性能急剧恶化, 低温工况下, 翅片蒸发器的片距尽量釆用 6mm 以上, 优选的翅片蒸发器的片距 6- 8mm
鉴于风冷式制冷具有速度快的特点, 而制冰室的湿度髙有可能降 低蒸发器的效率, 鉴于这样的矛盾, 因此决定选择在冷冻室中翅片式 蒸发器方式并结合蒸发器翅片等参数的选择以便达到一个较为理想的 平衡。
为了进一步筛选,本发明的研究人员 翅片式蒸发器的形状进行了 筛选, 参见附图 3 4, 三种换热器的几何参数如下:
Figure imgf000010_0001
结论表明, 在本发明的冷冻室风直冷混合方式中, 3 号蒸 效率优于其他二种蒸发器, 在本发明中作为优选的实施方式。
为了得到最佳的效率, 本发明的冷冻室和冷藏室来用二种不同的 蒸发器, 其中:
在所述冰箱的冷冻室中釆用蒸发器为翅片式蒸发器, 冷冻室通过 直冷方式进行制冷, 而制冰室通过冷冻风机强制进行间室内空气对流 达到制冷目的; 制冰室温度达到设定温度后,; 冷冻风机停止, 如果冷 冻室温度尚未达到指定温度, 冷冻室蒸发器继续工作, 如果冷冻室温 度也达到指定温度, 则冷冻温控器向脉冲电磁阀发出脉冲信号, 脉冲 电磁阀动作, 切断制冷剂的冷冻制冷循环; 在所述的翅片式蒸发器上设置加热丝, 在需要化霜时, 定时器控 制加热丝加热以自动化除翅片上的结冰。
所述的翅片蒸发器, 紧贴地安装在冷冻室内胆外, 负责冷冻室和 制冰室的制冷, 在冷冻室蒸发器的另一面形成一个间隙, 通过冷冻风 机使得制冰室的空气循环冷却, 所述制冰室的特点是能够快速制冷、 降温速度快, 冰块透明发亮。
至此, 本发明的制冷系统的选择已经完成, 以下是对制冰机部分 的设计:
本发明所述的冰箱的自动制冰, 就是要在控制上和 构上实现制 冰系统能够自动完成一个完整的制冰过程并循环此过程 这样就实现 了冰箱的自动制冰。 这个过程可参见附图 4 :
1 )、 检冰是判断冰是否制好, 以温度来判断。
2 )、 脱冰是将制好的冰从制冰盒脱到储冰盒内。
3 )、 进水是靠水泵或水阀将水注入到制冰盒内。
4 )、 延时等待制冰盒内的水结成冰。 具体实施方式
