Description

制冷系统及具有该制冷系统的水箱
技术领域
本发明涉及水箱制冷技术领域, 特别是涉及一种制冷系统及具有该制冷系统的水箱。 背景技术
由于水箱制冷剂具有易燃易爆特性, 为了防止由于制冷剂泄漏而引发的危险, 各国均对 同一种制冷剂在同一个水箱内的浓度有严格规定。
随着大容积水箱的出现, 例如容积大于 600L的水箱, 为了满足水箱的制冷效果, 往往 需要增加制冷剂的使用量,进而导致制冷剂浓度超过标准,造成了水箱在使用中的潜在危险。 然而,各个水箱制造厂商均不能提出一个有效的解决方案以兼顾大容积水箱的制冷效果和制 冷剂的安全问题。
另外,现有的水箱无论是釆用单压缩机还是釆用双压缩机的制冷系统均不能彻底解决双 温区和多温区温区真正独立运行的问题, 因此节能效果不佳。 发明内容
本发明旨在至少在一定程度上解决上述技术问题之一或至少提供一种有用的商业选择。 为此,本发明的一个目的在于提出一种具有两个独立运行且使用不同制冷剂的子制冷系统的 制冷系统。
本发明的另一个目的在于提出一种具有该制冷系统的水箱。
根据本发明一方面实施例的制冷系统, 包括彼此独立运行的第一子制冷系统和第二子制 冷系统, 其中所述第一子制冷系统包括: 第一压缩机; 第一冷凝器, 所述第一冷凝器的入口 与所述第一压缩机的出口相连; 第一毛细管, 所述第一毛细管的入口与所述第一冷凝器的出 口相连; 以及第一蒸发器, 所述第一蒸发器的入口与所述第一毛细管的出口相连, 而所述第 一蒸发器的出口与所述第一压缩机的入口相连; 及所述第二子制冷系统包括: 第二压缩机; 第二冷凝器, 所述第二冷凝器的入口与所述第二压缩机的出口相连; 第二毛细管, 所述第二 毛细管的入口与所述第二冷凝器的出口相连; 以及第二蒸发器, 所述第二蒸发器的入口与所 述第二毛细管的出口相连, 而所述第二蒸发器的出口与所述第二压缩机的入口相连。
由此, 本发明实施例的制冷系统, 通过彼此独立运行的第一子制冷系统和第二子制冷系 统, 在达到制冷温度后, 能够彻底关闭对应的子制冷系统, 从而真正实现制冷系统的独立控 制, 达到节能的目的。 另外, 独立运行的第一子制冷系统和第二子制冷系统还能够减少第一 压缩机和第二压缩机的启动频率, 从而延长水箱的使用寿命。
另外, 根据本发明上述实施例的制冷系统还可以具有如下附加的技术特征:
根据本发明的一个实施例, 所述第一子制冷系统使用第一制冷剂, 所述第二子制冷系统 使用与所述第一制冷剂不相同的第二制冷剂。
由于第一子制冷系统和第二子制冷系统釆用不同的制冷剂, 当发生两种制冷剂同时泄露 时, 不同种类的制冷剂混合后不会总成同种制冷剂浓度的升高, 因此有效避免了制冷剂引发 的安全隐患。 同时, 本发明的制冷系统, 通过两套独立运行的子制冷系统分别釆用不同的制 冷剂, 完全能够满足目前大容积水箱对制冷效果的要求。
才艮据本发明的一个实施例,所述第一子制冷系统还包括设在所述第一冷凝器和所述第一 毛细管之间的第一干燥过滤器和设在所述第一蒸发器和所述第一压缩机之间且用于储存所 述第一制冷剂的第一储液器;所述第二子制冷系统还包括设在所述第二冷凝器和所述第二毛 细管之间的第二干燥过滤器和设在所述第二蒸发器和所述第二压缩机之间且用于储存所述 第二制冷剂的第二储液器。

由此,才艮据本发明实施例的水箱,第一子制冷系统和第二子制冷系统釆用不同的制冷剂, 当发生两种制冷剂同时泄露时, 不同种类的制冷剂混合后不会使同种制冷剂浓度升高, 因此 有效避免了制冷剂引发的安全隐患。 同时, 本发明的水箱釆用大容积设计时, 通过两套独立 运行的子制冷系统分别釆用不同的制冷剂,不仅能够保证水箱的制冷效果且还能够达到节能 的目的。
另外, 根据本发明上述实施例的水箱还可以具有如下附加的技术特征:
才艮据本发明的一个实施例, 所述第一制冷间室为冷藏室, 所述第二制冷间室为冷冻室且 在左右方向上与所述第一制冷间室并排设置。

具体而言, 第二冷凝器 11的入口与第二压缩机 21的出口相连, 第二毛细管 23的入口 与第二冷凝器 22的出口相连, 第二蒸发器 24的入口与第二毛细管 23的出口相连, 而第二 蒸发器 24的出口与第二压缩机 21的入口相连。 由此形成第二制冷循环。
第一子制冷系统 1的压缩机 11和第二子制冷系统 1的压缩机 21可以釆用并联控制, 因 此能够实现第一子制冷系统 1和第二子制冷系统 21的单独启动或关闭。
由此, 本发明实施例的制冷系统, 通过彼此独立运行的第一子制冷系统 1和第二子制冷 系统 2 , 在达到制冷温度后, 能够彻底关闭对应的子制冷系统, 从而真正实现制冷系统的独 立控制, 达到节能的目的。 另外, 独立运行的第一子制冷系统 1和第二子制冷系统 2还能够 减少第一压缩机 11和第二压缩机 21的启动频率, 从而延长水箱的使用寿命。
根据本发明的一个实施例, 第一子制冷系统 1使用第一制冷剂 a , 第二子制冷系统 2使 用与第一制冷剂 a不相同的第二制冷剂 b。 相对于每个子制冷系统, 制冷剂的浓度均应按照 各国对该制冷剂的标准严格执行。
才艮据本发明一个实施例的制冷系统, 由于第一子制冷系统 1和第二子制冷系统 2釆用不 同的制冷剂, 当发生两种制冷剂同时泄露时, 不同种类的制冷剂混合后不会总成同种制冷剂 浓度的升高, 因此有效避免了制冷剂引发的安全隐患。 同时, 本发明的制冷系统, 通过两套 独立运行的子制冷系统分别釆用不同的制冷剂,完全能够满足目前大容积水箱对制冷效果的 要求。
本发明实施例的制冷系统可以釆用多种制冷剂, 优选地, 第一制冷剂 a和第二制冷剂 b 选自制冷剂 R280, R600A和 R1 34A。
如图 1所示,第一子制冷系统 1还包括设在第一冷凝器 12和第一毛细管 1 3之间的第一 干燥过滤器 15和设在第一蒸发器 14和第一压缩机 11之间且用于储存第一制冷剂 a的第一 储液器 16。 相对应地, 第二子制冷系统 1还包括设在第二冷凝器 11和第二毛细管 23之间 的第二干燥过滤器 25和设在第二蒸发器 24和第二压缩机 21之间且用于储存第二制冷剂 b 的第二储液器 26。
下面参考图 3来描述根据本发明实施例的水箱。
根据本发明实施例的水箱,包括: 箱体 3、 门体(图中未示)和制冷系统。
具体而言,箱体 3内具有第一制冷间室 31和第二制冷间室 32。第一制冷间室 31为冷藏 室, 第二制冷间室 32为冷冻室, 且冷藏室与冷冻室在左右方向上并排设置。 门体可枢转地 设在箱体上以打开和关闭第一制冷间室 31和第二制冷间室 32。
制冷系统为上述任一项实施例所述的制冷系统,其中第一子制冷系统 1釆用第一制冷剂 a并用于对第一制冷间室 31制冷, 第二子制冷系统 1釆用第二制冷剂 b并用于对第二制冷 间室 32制冷。
由此, 才艮据本发明实施例的水箱, 第一子制冷系统 1和第二子制冷系统 2釆用不同的制 冷剂,当发生两种制冷剂同时泄露时,不同种类的制冷剂混合后不会使同种制冷剂浓度升高, 因此有效避免了制冷剂引发的安全隐患。 同时, 本发明的水箱釆用大容积设计时, 通过两套 独立运行的子制冷系统分别釆用不同的制冷剂,不仅能够保证水箱的制冷效果且还能够达到 节能的目的。
才艮据本发明的一个实施例, 第一子制冷系统 1可以包括多个第一毛细管 13和多个第一 蒸发器 14 , 对应地, 第二子制冷系统 2同样可以包括多个第二毛细管 23和多个第二蒸发器 24。 这样可以使本法的水箱具有多个变温室, 增强了水箱的使用性且拓展了水箱的功能。
根据本发明的一些实施例,第一压缩机 11和第一冷凝器 12设在箱体 3的下部且位于冷 冻室一侧, 而第二压缩机 21和第二冷凝器 22设在箱体 3的下部且位于冷藏室一侧。
考虑到对冷藏室制冷的第一压缩机 11开机率相对较低且产生的热量较小, 而对冷冻室 制冷的第二压缩机 21所产生的热量较大, 因此釆用上述设置方式, 即将第一压缩机 11和第 一冷凝器 12设置在冷冻室一侧, 而将第二压缩机 21和第二冷凝器 11设置在冷藏室一侧, 能够有效提高冷冻室制冷效率, 最大限度地减小箱体 3内的冷气损失, 从而达到有效节能的 目的。
根据本发明实施例的水箱包括设在箱体 3下部且邻近第二压缩机 21的冷藏室化霜水接 水盘 41 , 和设在箱体 3下部且位于第一压缩机 11上面的冷冻室化霜水接水盘 42。 冷冻室化 霜水接水盘 42的水平高度高于冷藏室化霜水接水盘 41且与冷藏室化霜水接水盘 41连通, 因此化霜水流入到冷冻室化霜水接水盘 42内后再流入冷藏室化霜水接水盘 41 , 而冷藏室内 的化霜水则直接流入冷藏室化霜水接水盘 41内。由于冷藏室化霜水接水盘 41邻近温度高的 第二压缩机 21 , 因此有利于蒸发收集在冷藏室化霜水接水盘 41内的化霜水。
另外,根据本发明实施例的水箱还包括设在冷藏室内的冷藏风机和检测所述冷藏室化霜 的化霜传感器(图中为示)。 在第一子制冷系统 1工作时, 冷藏风机启动, 将冷气输送到冷 藏室内。 而在冷藏室化霜过程中 (关闭第一子制冷系统 1 ), 冷藏风机根据化霜传感器的指 令在化霜过程中保持运转, 以将化霜时产生的湿润空气带入冷藏室内, 这样不仅能够提高冷 藏室内温度的均匀性, 还能够提高冷藏室内的湿度, 延长冷藏食物的保鲜时间。
在本说明书的描述中, 参考术语 "一个实施例"、 "一些实施例"、 "示例"、 "具体示例"、 或 "一些示例" 等的描述意指结合该实施例或示例描述的具体特征、 结构、 材料或者特点包 含于本发明的至少一个实施例或示例中。在本说明书中, 对上述术语的示意性表述不一定指 的是相同的实施例或示例。 而且, 描述的具体特征、 结构、 材料或者特点可以在任何的一个 或多个实施例或示例中以合适的方式结合。
尽管上面已经示出和描述了本发明的实施例, 可以理解的是, 上述实施例是示例性的, 不能理解为对本发明的限制,本领域的普通技术人员在不脱离本发明的原理和宗旨的情况下 在本发明的范围内可以对上述实施例进行变化、 修改、 替换和变型。
