The invention belongs to the technical field of the cooling system, and more particularly relates to a cooling system for residential applications, for example, a refrigeration device comprising at least two environmental compartments at different temperatures. To solve the problem in the evaporative cooling system, when the heat load in just one line in the evaporation greatly increases, the normal increase refrigerant temperature will occur out of the line of the evaporator evaporation, thus increasing the formation of evaporation route as part of the expansion of the throttle. Increase the throttle flow produced two major related issues, including: gradually reduce the refrigerant fluid supplied to the evaporator the evaporation line of the body, another flow refrigerant evaporator evaporation route and did not arrive by the first evaporator the refrigerant fluid caused by excess of gradually overload. Therefore, as it increases the heat load, if an evaporator is \warming\, it may be that the evaporator is stopped supplying, and in turn may be another evaporator overload. Solution: the evaporative cooling system is disclosed wherein the middle of the first line of the evaporation heat exchanger comprises at least a portion of the second row of the evaporation line (preferably defined between the evaporator and the compressor suction fluid entrance portion of the physical layout) of the contact expansion device of at least one section, and the middle second evaporation route the heat exchanger comprises at least a part of the first evaporation route (preferably defined between the evaporator and the compressor suction fluid entrance portion of the section) at least one expansion device physical layout of the contact. Considering the influence of the temperature of the refrigerant heat exchanger in the middle of the first line of the evaporation flow in second evaporation line expansion device in temperature, and the temperature of refrigerant in the first evaporation route flow expansion device of temperature effect between second line evaporation heat exchanger. The invention is characterized in that the corresponding changing throttle expansion device therefore, and change the quality of not properly to prevent refrigerant between at least two separate evaporation line transfer.
【技术实现步骤摘要】
本专利技术的主题涉及一种多蒸发冷却系统,即具有至少两个功能上分离的蒸发器的冷却系统,其在不同的温度范围和压力下运行。更具体地说,本专利技术的主题进一步涉及通过内部换热器集成的多蒸发冷却系统,内部换热器交叉地布置,即每个内部换热器设置成冷却单独的和不同的蒸发路线的属于相同的制冷剂流体。
技术介绍
如本领域技术人员已知的,冷却系统通常包括压缩机、经过膨胀装置和蒸发器的冷凝器。这些构件流体地互相连接,以限定用于能改变整个冷却系统的状态和温度的制冷剂流体的循环回路。常规冷却系统的所有功能动态特性被本领域技术人员广泛认知,并且在专门的技术文献中广泛地公开。本领域技术人员还已知的是,类似用于家用冰箱的某些常规的冷却系统,其包括膨胀装置是毛细管的传统装置,物理地接触(焊接或卷起)作为换热器的蒸发器的出口导管。这种装置的总原则在于,通过在膨胀装置中流动的制冷剂的强制冷却而优化冷却系统的效率,这提供降低的流动节流,增加单位制冷能力并且导致增加系统冷却性能。如本领域技术人员已知的,功能地示出的这种传统的装置是,离开蒸发器的制冷剂的温度比离开冷凝器的制冷剂的温度更低并且被送往膨胀装置。因此,在毛细管和蒸发器出口导管(内部换热器)之间的物理地接触产生冷却流入毛细管的制冷剂的条件。在另一方面,也已知的是多蒸发冷却系统,或集成的冷却系统,至少一个压缩机、至少一个冷凝器、至少两个膨胀装置和至少两个蒸发器在不同的温度范围和压力独立地运行。这类冷却系统的功能动态特性是非常类似于常规冷却系统的功能动态特性。通常,多蒸发冷却系统的建造方案和应用可能性是大量的并且在专利文件中已经很好的研究了。 ...
