在本实施例中提供了一种运行于上述移动终端或网络架构的气液换热处理方法，图2是根据本公开实施例的气液换热处理方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，确定泵前过冷度所属温度区间；
步骤S204，确定所述泵前过冷度所属温度区间对应的三通阀的目标动作开度；
本公开实施例中，上述步骤S204具体可以包括：根据预先设置的不同温度区间的过冷度与三通阀的动作开度的对应关系确定所述泵前过冷度所属温度区间对应的所述三通阀的目标动作开度。
步骤S206，根据所述目标动作开度对所述三通阀进行控制。
本公开实施例中，上述步S206具有可以包括：在所述目标动作开度为负的情况下，根据所述目标动作开度控制关闭所述三通阀，例如，当所述泵前过冷度所属温度区间为[t N-1，t 1)，三通阀需要较快速关闭，避免过冷度下调过大；在所述目标动作开度为零的情况下，根据所述目标动作开度控制所述三通阀不动作，例如，当所述泵前过冷度所属温度区间为[t 1，T 1)时，目标动作开度为零，三通阀不动作；在所述目标动作开度为正的情况下，根据所述目标动作开度控制打开所述三通阀，当所述泵前过冷度所属温度区间为[T 1，T M]，三通阀需要快速打开，避免温度过冲。
通过上述步骤S202至S206，确定泵前过冷度所属温度区间；确定所述泵前过冷度所属温度区间对应的三通阀的目标动作开度；根据所述目标动作开度对所述三通阀进行控制，可以解决相关技术中两相系统中通过PID调节方式对三通阀进行开度控制出现震荡超调现象的问题，通过对三通阀的开度进行分段控制，在系统负荷大范围变化时，仍然能快速将泵前温度控制在需求范围之内，可以保证系统长期安全可靠运行，避免泵气蚀、进液过冷度低的风险。
在一示例性实施例中，在上述步骤S204之前，对所述泵前过冷度所处温度区间进行分段，得到多个温度区间；分别确定所述多个温度区间对应的所述三通阀的动作开度，具体的，分别根据预先为每个温度区间设置的多个所述三通阀的动作开度对所述三通阀进行控制，从多个所述三通阀的动作开度中确定一个满足预设条件的动作开度，作为所述每个温度区间对应的所述三通阀的动作开度，得到所述多个温度区间对应的所述三通阀的动作开度；保存所述多个温度区间的过冷度与所述三通阀的动作开度的对应关系。
在另一示例性实施例中，在上述步骤S202之前，获取储液罐的温度，并将所述储液罐的温度确定为泵前蒸发温度；获取冷凝器出口与泵入口温度，并将所述冷凝器出口与泵入口温度确定为泵前温度；将所述泵前蒸发温度与所述泵前温度的差值确定为所述泵前过冷度。
图3是根据本公开实施例的泵驱两相系统的示意图，如图3所示，泵驱两相系统包括储液罐气液两相，T罐即泵前蒸发温度，T泵前为冷凝器出口与泵入口温度，两者之差即为泵前过冷度T过冷(一般要求≥3℃)；三通阀开度0～100％之间，开度越大冷凝器换热越剧烈，T 泵前越低，T过冷越大。②系统功耗发生变化时，三通阀开度自动发生变化，基于背景技术中的问题，在三通阀进行换热调节时，易出现震荡超调现象，无法控制在需求温度范围内，甚至导致T过冷小于3℃。
系统最小功耗运行，三通阀对应最小开度X；在系统刚启动运行时，负载热量无法将进液温度快速升高，有较长一段时间泵前过冷度处于较低的情况下，三通阀很可能一直关闭至0，打开过程较慢，容易出现过冷度过冲小于3℃，泵出现气蚀。
假设泵前过冷度目标值为T0(T0＞3℃)；在测试过程中发现，基于两相系统的运行特性和三通阀自身特性，气液换热在不同区段内呈现不同特征，一套比例调节策略无法适应各区段换热特征。泵前过冷度控制很不稳定。
本公开实施例采用分段比例控制，以过冷度所处温度区间及其换热表现进行分段，每段中通过定义K值(决定每次动作的开度)和动作频率(每两次动作间隔时间)来执行控制。认为动作频率和系统特性(基于三通阀调节的气液换热响应时间)相关，采用固定值。K值与换热强度相关，需要分段选用最佳值。
图4是根据本公开实施例的泵前过冷度所属温度区间的示意图，如图4所示，当泵前过冷处于[T 1，T M]，三通阀需要快速打开，避免温度过冲，则温度上升的速度越来越快，K值逐渐增大；当泵前过冷处于[t N-1，t 1)，三通阀需要较快速关闭，避免过冷度下调过大，温度下降的速度越来越快，K值逐渐增大；当泵前过冷处于[t N，t N-1)，这个阶段K值需尽可能小，避免开阀过程三通阀起始值过低、降温起始点过高导致泵前过冷度过低，出现气蚀；当泵前过冷处于[t 1，T 1)时，三通阀不动作。
针对现有技术中，设定三通阀最低开度X，关阀过程中，当三通阀开度达到X后，停止关阀。
三通阀动作周期为10s，三通阀各区段K值及对应动作幅度如表1所示，其中，动作幅度即上述的动作开度。分别根据预先为每个温度区间设置的多个所述三通阀的动作开度对所述三通阀进行控制，从多个所述三通阀的动作开度中确定一个满足预设条件的动作开度，作为所述每个温度区间对应的所述三通阀的动作开度，得到所述多个温度区间对应的所述三通阀的动作开度表1中灰色突出显示的为确定出的不同温度区间对应的三通阀的动作开度，不同系统确定出的不同温度区间对应的三通阀的动作开度可能不同，确定方式与本公开描述相同。

对应某一个系统，三通阀动作周期和K值取决于外冷在某一工况下的具体取值(流量、温度)，本公开实施例中，默认流量是不变的，当此状态发生变化，控制参数也随机发生变化。
通过本公开实施例，系统功耗发生变化时，泵前过冷度可以被精准调节，调解过程中不会出现超调现象；分段调节在保证不超调的情况下最大可能提升调节速度。
