在本实施例中，若所述第二差值小于所述第一阈值，则进一步判断所述第二差值是否小于第二阈值，其中，所述第一阈值大于所述第二阈值。即判断TP-T2＜5是否成立，当TP-T2＜5，减小所述喷焓电子膨胀阀11的开度参数，以减小所述喷焓电子膨胀阀11输出的冷媒量，如控制喷焓压缩机1以预设频率F运行，喷焓电子膨胀阀11由当前开度每20s关小10度，之后每3min后再检测TP-T2的值。
在一实施例中，所述步骤S10之后，还包括：在所述第一差值不大于所述第一温度阈值且不小于第二温度阈值时，判断所述第二差值是否不小于第一阈值，其中，所述第二温度阈值小于所述第一温度阈值；若所述第二差值不小于所述第一阈值，则控制所述喷焓电子膨胀阀11保持当前开度参数，以维持所述喷焓电子膨胀阀11当前输出的冷媒量，并通过所述喷焓电子膨胀阀11对输出的一路冷媒进行节流降压。若所述第二差值小于所述第一阈值，则在所述第二差值小于所述第二阈值时，减小所述喷焓电子膨胀阀11的开度参数，以减小所述喷焓电子膨胀阀11输出的冷媒量，通过所述喷焓电子膨胀阀11对输出的一路冷媒进行节流降压，其中，所述第一阈值大于所述第二阈值；若所述第二差值小于所述第一阈值且不小于所述第二阈值，则控制所述喷焓电子膨胀阀11保持当前开 度参数，以维持所述喷焓电子膨胀阀11当前输出的冷媒量，并通过所述喷焓电子膨胀阀11对输出的一路冷媒进行节流降压。
在本实施例中，在所述第一差值不大于所述第一温度阈值且不小于第二温度阈值时，如1≤Ts-T1≤4，即室内温度与设定温度差值适中，需要制热量输出适中。进一步判断所述第二差值是否不小于第一阈值，其中，所述第二温度阈值小于所述第一温度阈值，即判断10≤TP-T2是否成立。当10≤TP-T2，控制喷焓压缩机1以预设频率F运行，喷焓电子膨胀阀11维持初始开度参数P初始运行；当5≤TP-T2＜10，控制喷焓压缩机1以预设频率F运行，喷焓电子膨胀阀11以初始开度参数P维持运行；当TP-T2＜5，控制喷焓压缩机1以预设频率F运行，喷焓电子膨胀阀11关闭，之后每3min后再检测TP-T2的值。
在一实施例中，所述步骤S10之后，还包括：在所述第一差值小于所述第二温度阈值且大于第三温度阈值时，关闭所述喷焓电子膨胀阀11，并减小所述喷焓压缩机1的工作频率。
本实施例中，在所述第一差值小于所述第二温度阈值且大于第三温度阈值时，如-1＜Ts-T1＜1，即室内温度与设定温度差值相近，基本达到用户设定值，需要制热量输出很小，则喷焓电子膨胀阀11关闭，控制喷焓压缩机1的压缩频率由初始值F降到最低频率F0运行。
