本发明上述一个或多个技术方案，至少具有如下一种或多种有益效果：
在实施本发明的技术方案中，首先获取空调选型输入参数并根据换热管污垢系数对空调选型输入参数中的冷水温度输入值进行温度修正，然后基于预设的制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系并且根据修正后的冷水温度、制冷量输入值和换热装置类型，获取每类换热装置各自对应的与修正后的冷水温度接近的多个冷水温度、与所述制冷量输入值接近的多个制冷量以及相应的多个制冷功率，最后根据修正后的冷水温度与制冷量输入值，以及获取到的每类换热装置各自对应的多个冷水温度、多个制冷量和多个制冷功率降进行插值计算，根据计算结果获取并输出在修正后的冷水温度与制冷量输入值的条件下每类换热装置各自对应的制冷功率，根据制冷量输入值与制冷功率计算每类换热装置各自对应的压降，进而能够根据压降以及预设的压降需求选取相应类型的换热装置。通过插值计算的方式计算在空调选型输入参数的条件下不同换热装置的制冷功率，进而计算得到不同换热装置的压降，使得即使空调选型输入参数不符合特定的标准工况的要求，也可以对通过“预设的制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系”获取到的制冷量插值得出在当前空调选型输入参数的条件下换热装置的准确制冷量，进而计算得到准确的压降值并根据该压降值判断是否满足实际的压降需求，根据判断结果决定是否选择使用该换热装置。同时，由于不同换热装置对应的插值计算过程相互独立，不存在干扰和影响，因此本发明能够同时对当前空调选型输入参数的条件下的多个换热装置进行选型计算。

具体实施方式
下面参照附图来描述本发明的一些实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。
在本发明的描述中，“装置”、“处理器”可以包括硬件、软件或者两者的组合。一个装置可以包括硬件电路，各种合适的感应器，通信端口，存储器，也可以包括软件部分，比如程序代码，也可以是软件和硬件的组合。处理器可以是中央处理器、微处理器、数字信号处理器或者其他任何合适的处理器。处理器具有数据和/或信号处理功能。处理器可以以软件方式实现、硬件方式实现或者二者结合方式实现。非暂时性的计算机可读存储介质包括任何合适的可存储程序代码的介质，比如磁碟、硬盘、光碟、闪存、只读存储器、随机存取存储器等等。术语“A和/或B”表示所有可能的A与B的组合，比如只是A、只是B或者A和B。术语“至少一个A或B”或者“A和B中的至少一个”含义与“A和/或B”类似，可以包括只是A、只是B或者A和B。单数形式的术语“一个”、“这个”也可以包含复数形式。
首先需要说明的是，换热装置是空调必不可少的关键设备，水冷空调工作在制冷模式时冷冻水在换热装置内气化吸热，可以实现制冷的目的；水冷空调 工作在制热模式时冷却水在换热装置内液化放热，可以实现制热的目的。空调选型指的是在水冷空调研发设计时根据设计需求对空调及其换热装置等设备的关键参数进行选择与确定。其中，换热装置的关键参数可以包括冷水流入侧与冷水流出侧之间的压降。
现有技术中传统的水冷空调系统选型软件只能根据符合特定标准(例如：中华人民共和国国家标准GB/T 18430.1-2007规定的工况)的换热装置参数(例如：蒸发器的冷冻水出水温度、冷凝器的冷却水进水温度和冷水流量)进行选型计算并且针对每个制冷量需求只能提供一种换热装置类型，而空调的实际运行工况往往并不符合特定标准工况的要求，因此上述水冷空调系统选型软件并不适用于对运行在非特定标准工况的空调进行换热装置选型。
在本发明实施例中空调选型方法首先获取空调选型输入参数(包括但不限于：冷水温度输入值、换热管污垢系数、制冷量输入值以及一个或多个换热装置类型等)并对空调选型输入参数中的冷水温度输入值进行温度修正，然后基于预设的制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系并且根据修正后的冷水温度、制冷量输入值和换热装置类型，获取每类换热装置各自对应的与修正后的冷水温度接近的多个冷水温度、与制冷量输入值接近的多个制冷量以及相应的多个制冷功率，最后根据修正后的冷水温度与制冷量输入值，以及获取到的每类换热装置各自对应的多个冷水温度、多个制冷量和多个制冷功率进行插值计算，根据计算结果获取并输出在修正后的冷水温度与制冷量输入值的条件下每类换热装置各自对应的制冷功率，根据制冷量输入值与制冷功率计算每类换热装置各自对应的压降，进而能够根据压降以及预设的压降需求选取相应类型的换热装置。通过插值计算的方式计算在空调选型输入参数的条件下不同换热装置的压降，使得即使空调选型输入参数不符合特定的标准工况的要求，也可以对通过“预设的制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系”获取到的压降插值得出在当前空调选型输入参数的条件下换热装置的准确制冷量，进而计算得到准确的压降值并根据该压降值判断是否满足实际的压降需求，根据判断结果决定是否选择使用该换热装置。同时，由于不同换热装置对应的插值计算过程相互独立，不存在干扰和影响，因此本发明能够同时对当前空调选型输入参数的条件下的多个换热装置进行选型计算。
参阅附图1，图1是根据本发明的一个实施例的空调选型方法的主要步骤流程图。如图1所示，本发明实施例中空调选型方法主要包括以下步骤：
步骤S101：获取空调选型输入参数，空调选型输入参数包括冷水温度输入值、换热管污垢系数、制冷量输入值以及一个或多个换热装置类型。
冷水温度输入值指的是换热装置的冷水流入侧的温度输入值和冷水流出侧的温度输入值。例如：当换热装置是蒸发器时，冷水温度输入值包括蒸发器的冷冻水进水温度和冷冻水出水温度；当换热装置是冷凝器时，冷水温度输入值包括冷凝器的冷却水进水温度和冷却水出水温度。
换热管污垢系数指的是能够表示换热装置中换热管结垢大小程度的系数，换热管污垢系数的具体数值可以根据实际运行工况设定。例如：当实际运行工况是中华人民共和国国家标准GB/T 18430.1-2007规定的工况时，可以根据该标准中规定的换热管污垢系数的取值范围设定换热管污垢系数的具体数值。一个例子：当换热装置是蒸发器时换热管污垢系数是0.018m 2K/kW，当换热装置是冷凝器时换热管污垢系数是0.044m 2K/kW。
制冷量输入值指的是空调制冷量的输入值。一个例子：制冷量输入值是530kW。
换热装置类型指的是换热装置的类型如型号信息。一个例子：当换热装置是蒸发器时，换热装置类型可以包括蒸发器A、蒸发器B和蒸发器C。
步骤S102：根据换热管污垢系数计算冷水修正温度，根据冷水修正温度对冷水温度输入值进行修正计算，得到修正后的冷水温度。其中，当换热装置是蒸发器时，修正后的冷水温度是蒸发器的冷冻水出水温度；当换热装置是冷凝器时，修正后的冷水温度是冷凝器的冷却水进水温度。
当换热装置的换热管内发生结垢时，结垢产生的污垢会影响换热装置的换热能力，进而影响换热装置的冷水流出侧的温度，利用换热管污垢系数对冷冻水出水温度和冷却水进水温度进行修正，可以得到更加接近实际运行工况的换热装置的冷冻水出水温度和冷却水进水温度。
在本实施例中可以采用中华人民共和国国家标准GB/T 18430.1-2007规定的污垢系数修正温度计算方法来计算，具体地可以根据下式(1)所示的方法计算冷水修正温度：
Figure PCTCN2021071457-appb-000009
公式(1)中各参数含义是：TD是冷水修正温度，S是小温差且S＝|t s-t wl|，R是进出水温差且＝|t wl-t we|，
Figure PCTCN2021071457-appb-000010
ILMTD＝f×(q/A)，t s是换热温度(如蒸发温度或冷凝温度)，t we是换热装置的冷水流入侧温度(如冷却水进水温度)，t wl是换热装置的冷水流出侧温度(如冷却水出水温度)，f是换热管污垢系数，q是制冷量，A是换热管内侧(污垢所在的一侧)的换热总面积。
在本实施例中在计算得到冷水修正温度后，可以按照以下步骤对冷水温度输入值进行修正计算，得到修正后的冷水温度(冷冻水出水温度或冷却水进水温度)：
根据冷冻水出水温度的输入值与冷水修正温度的温度差值获取修正后的冷冻水出水温度。一个例子：修正后的冷冻水出水温度等于或接近于该温度差值。根据冷却水进水温度的输入值与冷水修正温度的温度和值获取修正后的冷却水进水温度。一个例子：修正后的冷却水进水温度等于或接近于该温度和值。
步骤S103：基于预设的制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系并且根据修正后的冷水温度、制冷量输入值与换热装置类型，获取每类换热装置各自对应的与修正后的冷水温度接近的多个冷水温度、与制冷量输入值接近的多个制冷量以及相应的多个制冷功率。
“预设的制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系”中的各个参数均可以是研发设计人员在不同的制冷量、制冷功率等条件下进行实际运行测试得出的，进而再根据实际运行测试结果构建各个参数的对应关系。
以换热装置类型分别是A、B和C为例对步骤S103中获取与修正后的冷水温度接近的冷水温度以及与制冷量输入值接近的制冷量作进一步说明。
首先，针对换热装置A、B和C分别构建相应的“制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系a、b和c”。然后，根据对应关系a获取与修正后的冷水温度接近的多个冷水温度如Ta1和Ta2，与制冷量输入值接近的多个制冷量如Ca1和Ca2，以及根据对应关系a得到的与Ta1和Ca1对应的制冷功率Pa1，根据对应关系a得到的与Ta2和Ca2对应的制冷功率Pa2。换热装置B和C的冷水温度、制冷量和制冷功率的获取方法与上述换热装置A的类似，为了描述简洁，在此不再赘述
步骤S104：根据修正后的冷水温度与制冷量输入值，以及获取到的每类换热装置各自对应的多个冷水温度、多个制冷量和多个制冷功率进行插值计算。
插值计算是数据计算领域的常规计算方法，其目的是为了计算得到已知数据区间内的任意一点的值。一个例子：假设与A1对应的数据是B1，与A2对应的数据是B2，已知与A对应的数据是B，A介于A1和A2之间，则可以按照公式(A1-A)/(A1-A2)＝(B1-B)/(B1-B2)计算得出A的数值，具体是：根据(A1-A)/(A1-A2)＝(B1-B)/(B1-B2)可知：(A1-A)＝(B1-B)/(B1-B2)×(A1-A2)，进而得到A＝A1－(B1-B)/(B1-B2)×(A1-A2)＝A1+(B1-B)/(B1-B2)×(A2-A1)。其中A1、A2、B1、B2、B都是已知数据。
在本实施例中“预设的制冷量、制冷功率、冷水温度与换热装置类型之间的一一对应关系”中的各数据都是已知数据，插值计算的目的是为了计算出与修正后的冷水温度(冷冻水出水温度或冷却水进水温度)以及制冷量输入值对应的制冷功率。
步骤S105：根据计算结果获取并输出在修正后的冷水温度与制冷量输入值的条件下每类换热装置各自对应的制冷功率，根据制冷量输入值与该制冷功率计算每类换热装置各自对应的压降，以便能够根据压降以及预设的压降需求选取相应类型的换热装置。
计算结果指的是步骤S104中插值计算得出的与修正后的冷水温度和制冷量输入值对应的制冷功率。压降指的是换热装置中冷水流入侧与冷水流出侧之间的压降。
在本实施例中可以根据制冷量输入值与制冷功率并按照以下式(2)所示的方法计算换热装置的压降：
Figure PCTCN2021071457-appb-000011
公式(2)中各参数含义是：ΔP是换热装置的压降，γ是用于修正换热装置压降的系数且γ＞0，该系数可以由换热装置的供应商提供，N是换热装置的流程数(Number of pass)，f是换热装置的阻力系数，L是换热装置内换热管的长度，di是换热装置内换热管的内径，ρ是流体密度，v是流体流速且v＝G/(Si·3600)，G是冷水流量(冷冻水流量或冷却水流量)，Si是换热装置的流通面积且在本实施例中可以采用空调领域常规的换热装置流通面积计算方法来计算Si。
当换热装置是蒸发器时，冷水流量G表示冷冻水流量，当换热装置是冷凝器时冷水流量G表示冷却水流量。下面以参数G1表示冷冻水流量，参数G2表示冷却水流量为例，对冷冻水流量G1和冷却水流量G2的计算方法作具体说明。具体地，冷冻水流量G1和冷却水流量G2的计算公式如下式(3)所示：
Figure PCTCN2021071457-appb-000012
公式(3)中各参数含义是：Q是制冷量输入值，W是通过步骤S104的插值计算得到的制冷量输入值对应的制冷功率，ΔT是换热装置的进出水温差。
通过上述步骤可以得到在相同空调选型输入参数的条件下不同换热装置的压降，从而有利于空调设计人员根据实际的换热装置压降需求选择合适的换热装置。
进一步，在一个实施方式中图1所示的空调选型方法还可以包括针对任意负荷等级的空调选型计算步骤。该针对任意负荷等级的空调选型计算步骤具体包括：
步骤S201：以制冷量输入值为满载制冷量(制冷量输入值对应的负荷等级是100％负荷)，分别计算每个预设的目标负荷等级各自对应的第一制冷量计算值。
预设的目标负荷等级可以是90％负荷、80％负荷和70％负荷等等。第一制冷量计算值
Figure PCTCN2021071457-appb-000013
其中，C是制冷量输入值，G′是制冷量输入值对应的负荷等级，G是预设的目标负荷等级。一个例子：若制冷量输入值C＝5004kW，制冷量输入值对应的负荷等级G′＝100％，预设的目标负荷等级G＝90％，则第一制冷量计算值C1＝4504kW。
步骤S202：判断空调选型输入参数是否包括变流量参数；若是，则转至步骤S203；若否，则转至步骤S205。
变流量参数包括第一负荷等级输入值，当步骤S201中的某个预设的目标负荷等级小于等于第一负荷等级输入值时(例如：第一负荷等级输入值是70％负荷，某个预设的目标负荷等级是60％负荷)，则控制在该目标负荷等级下换热装置的流量为空调选型输入参数中的冷水流量输入值，即固定冷水流量控制。当步骤S201中的某个预设的目标负荷等级大于第一负荷等级输入值时(例如：第一负荷等级输入值是70％负荷，某个预设的目标负荷等级是80％负荷)，则根据空调选型输入参数中的其他参数进行插值计算得到在该目标负荷等级下换热装置的冷水流量，即变冷水流量控制。
步骤S203：基于预设的制冷量、制冷功率、冷水温度与冷水流量之间的一一对应关系并且根据第一制冷量计算值与空调选型输入参数中的冷水流量输入值，获取与第一制冷量计算值接近的多个制冷量、与冷水流量输入值接近的多个冷水流量，以及相应的多个制冷功率与多个冷水温度。
“预设的制冷量、制冷功率、冷水温度与冷水流量之间的一一对应关系”中的各个参数均可以是研发设计人员在不同的制冷量、制冷功率等条件下进行实际运行测试得出的，进而再根据实际运行测试结果构建各个参数的对应关系。本实施例中根据对应关系获取相关数据的方法与前述步骤S103中所述的根据对应关系获取相关数据的方法类似，为了描述简洁，在此不再赘述。
步骤S204：根据第一制冷量计算值、冷水流量输入值以及步骤S203获取到的多个制冷量、多个制冷功率与多个冷水温度进行插值计算，根据计算结果获取并输出在第一制冷量计算值与冷水流量输入值的条件下预设的目标负荷等级对应的制冷功率和冷水温度，根据第一制冷量计算值以及插值计算得到的制冷功率计算空调能效比COP1，随后停止选型计算。其中，空调能效比

C1是第一制冷量计算值，P是插值计算得到的制冷功率。通过步骤S201-步骤S204使得在预设的目标负荷等级下换热装置的冷水流量均为固定的冷水流量输入值，即固定冷水流量控制。本实施例中的插值计算过程与前述步骤S104中所述的插值计算过程类似，为了描述简洁，在此不再赘述。
步骤S205：基于预设的制冷量、制冷功率、冷水温度与冷水流量之间的一一对应关系并且根据第一制冷量计算值，获取与第一制冷量计算值接近的多个制冷量以及相应的多个制冷功率、多个冷水温度与多个冷水流量。
步骤S206：根据第一制冷量计算值以及步骤S205获取到的多个制冷量、多个制冷功率、多个冷水温度与多个冷水流量进行插值计算，根据计算结果获取并输出在第一制冷量计算值的条件下预设的目标负荷等级对应的制冷功率、冷水温度和冷水流量，根据第一制冷量计算值以及插值计算得到的制冷功率计算空调能效比COP1，随后停止选型计算。其中，空调能效比
Figure PCTCN2021071457-appb-000015
C1是第一制冷量计算 值，P是插值计算得到的制冷功率。通过步骤S201-步骤S204和步骤S206的使得在不同的预设的目标负荷等级下换热装置的冷水流量可以依据预设的目标负荷等级对应的第一制冷量计算值的变化而变化，即实现了冷水流量的变流量控制。本实施例中的插值计算过程与前述步骤S104中所述的插值计算过程类似，为了描述简洁，在此不再赘述。
进一步，在一个实施方式中，图1所示的空调选型方法在执行完步骤S204和步骤S206之后，还可以包括变水温控制步骤。该变水温控制步骤具体包括：
步骤S207：获取变水温参数中的第二负荷等级输入值和变水温度输入值。
步骤S208：根据第二负荷等级输入值、变水温度输入值和冷水温度输入值并按照下式(4)所示的方法计算每个预设的目标负荷等级各自对应的冷水温度计算值：

Figure PCTCN2021071457-appb-000017
T N_计算是满载对应的冷水温度计算值，T N_计算和T m_计算的数值分别取决于冷水温度输入值和变水温度输入值。一个例子：换热装置是冷凝器，冷水温度输入值中的冷却水进水温度是30℃，变水温参数中的冷却水进水温度是24℃，目标负荷等级包括10％负荷、20％负荷、30％负荷、40％负荷、50％负荷、60％负荷、70％负荷、80％负荷、90％负荷和100％负荷，第二负荷等级输入值是50％负荷，T N_计算和T m_计算可以分别是32℃和23℃，进而可以计算得到公差d＝1.8℃。依据上述数据以及公式(4)可以得到60％负荷至100％负荷的冷水温度计算值依次是24.8℃、26.6℃、28.4℃、30.2℃、32℃。
步骤S209：基于预设的制冷量、制冷功率、冷水温度与冷水流量之间的一一对应关系并且根据冷水温度计算值T n_计算与特定冷水流量参数，获取与冷水温度计算值T n_计算接近的多个冷水温度、与特定冷水流量参数接近的多个冷水流量以及相应的多个制冷量和多个制冷功率。
在本实施方式中若在执行完步骤S204之后执行变水温控制步骤，则特定冷水流量参数是空调选型输入参数中的冷水流量输入值。若在执行完步骤S206之后执行变水温控制步骤，则特定冷水流量参数是步骤S206根据插值计算结果输出的冷水流量。
步骤S210：根据冷水温度计算值T n_计算与特定冷水流量参数，以及获取到的多个冷水温度、多个冷水流量、多个制冷量和多个制冷功率进行插值计算，根据计算结果获取并输出在冷水温度计算值T n_计算与特定冷水流量参数的条件下预设的目标负荷等级对应的制冷量和制冷功率，根据制冷量与制冷功率计算空调能效比COP2。其中，空调能效比

进一步，在一个实施方式中，图1所示的空调选型方法在执行完步骤S204和步骤S206之后，还可以包括目标制冷量控制步骤。该目标制冷量控制步骤具体包括：
