S106，根据基准出水温度或基准回水温度、出水温度时间补偿值，确定温控目标值以控制主机的出水温度；
其中，A为大于零的常数，负荷时间补偿系数根据当前建筑物的使用情况进行预设，f1(室外气象参数)为当前室外气象参数对应的历史制冷量。
本申请提供的空调器的控制方法，通过当前数据库或者云端数据库获取当前建筑内的历史制冷数据，历史制冷数据具体包括了历史时间(单位对应年月日)，每个历史时间对应的历史气象参数和对应的历史制冷量；通过当前时间和当前室外气象参数与历史制冷数据进行对比分析，以得出当前制冷量预测值的关系式，该关系式具体为：当前制冷量预测值＝A*负荷时间补偿系数*f1，在该公式中，A为大于零的常数，负荷时间补偿系数根据当前建筑的使用情况进行预设，具体地，负荷时间补偿系数为受建筑物内部负荷影响的补偿系数，该补偿系数随使用建筑物的人员习惯和人流量相关，跟建筑物内的业态直接相关；f1(室外气象参数)为当前室外气象参数对应的历史制冷量。通过根据当前建筑内的当前使用情况设置对应的负荷时间补偿系数以调整历史制冷量进而得到当前制冷量的预测值。
进一步地，根据当前室外气象参数和历史出水温度得到出水温度的补偿值。最终根据基准出水温度或基准回水温度以及出水温度时间补偿值来确定温控目标值，并通过温控目标值来控制主机的出水温度。应用本申请提供的控制方法可以使空调器在工作过程中根据历史数据和当前室外环境综合分析出当前制冷量的预测值，并依据计算得到的当前制冷量预测值实时修正空调器的运行状态，从而使空调器可以针对当前环境的历史制冷数据、历史气象数据和当前气象数据做出随动调整，以保证该空调器可以在满足温度调节要求的同时，大幅度降低工作的能耗，从而在满足精确的负荷需求同时提供用户的舒适度、降低空调器的能耗，进而实现了空调器的负荷巡航，提升空调器控制的精准度，降低空调能耗，缩减用户使用成本的技术效果。
