S42: 控制器首先关闭空调器的室外机的液体管路, 间隔第二预定时间 后关闭室外机的气体管路, 间隔第三预定时间后关闭压缩机。 通过控制上述关机的过程, 可以使得在关机的过程中, 制冷剂存储在室 外机侧, 从而防止了在室内机侧残留制冷剂, 提高了安全性。 图 5是 居本发明实施例的优选的空调器的控制方法的流程图。 如图 5所示, 该方法包括以下步^^ 控制器在接收到开机信号的情况下,判断控制器内是否存储有报警字节。 在判断结果为是的情况下,使告警装置进行报警, 并使显示板显示故障代码。 然后停止开机程序。 在判断结果为否的情况下, 继续检测制冷剂探测器, 即, 探头是否有效。 如果探头失效, 显示故障代码以提醒更换探头。 然后停止开机程序。 如果探头有效, 启动开机程序, 并继续判断探头的状态标志位是否有效。 如果探头的状态标志位无效, 则使探头初始化。 如果探头的状态标志位有效, 则检测冷媒 (制冷剂) 的浓度, 以及判断 浓度是否超标。
在冷媒浓度超标的情况下, 制冷剂探测器的处理器发放报警信号给控制 器 IC。 然后执行以下步骤之一或任意多个的组合: 蜂呜器报警空调显示板显示故障代码; 报警字节写入控制器的记忆芯片; 以及 启动关机程序。 在执行关机程序时, 可以釆用上述提到的方法来执行关 机或者按照以下图 6所述的方法来关机。从而通过控制不同阀门的关机顺序, 使得减少或者防止制冷剂在室内机的残留, 或者尽可能的全部回收在室外机 侧。 结束流程。 图 6是根据本发明的空调器执行关机程序的控制方法的流程图。 如图 6所示, 该方法包括以下步 4聚: 步骤 1 , 控制器接收到关机信号。 步骤 2, 控制器判断空调器的运行状态; 步骤 3 , 控制器判断空调器是否处于制冷模式。 在判断结果为是的情况 下, 执行步骤 4, 在判断结果为否的情况下, 执行步骤 5。 步骤 4, 控制器首先控制第二电磁阀 431关闭。 然后执行步骤 6。 步骤 5 , 在空调器处于制热模式的情况下, 将制热模式转为制冷模式来 运行一段实践后, 然后执行步骤 4。 步骤 6, 在第二电磁阀 431关闭之后延迟预定时间。 步骤 7, 控制第一电磁阀 43关闭, 延迟一段时间后到步骤 8。 在存在压 力探测器的情况下, 在第二电磁阀 431关闭之后, 也可以通过检测第一电磁 阀 43 外的压力, 可以使得在室外机的入口压力为零的情况下, 再执行该步 骤, 从而使得制冷剂全部保留在室外机侧。 大大提高了安全性。 步骤 8, 关机结束。 无论是处于制冷模式还是制热模式, 空调器接收到开机信号时, 第一电
磁阀 43和第二电磁阀 431 与室内机风机可以同时开启 (例如, 较压缩机早 20s开启), 然后进入正常工作状态。 制冷状态下, 空调器接收到关机信号或者丙烷探测器检测到制冷剂浓度 超标, 空调启动关机程序, 控制第二电磁阀 431关闭, 切断室外机制冷剂进 入室内机的通道, 同时室内制冷剂仍可经大阀门回收进室外机, 经过 tl时间 (依机型制冷量不同具体定, 例如, 对 1P机时间约 10秒; 1.5P空调约 12s; 2P及以上, 约 15s ), 几乎全部制冷剂都进入室外机, 此时再关闭第一电磁阀 43 , 经过 t2时间后, 空调器再控制压缩机停机, 从而整机关机。 制热状态下, 空调器接收到关机信号, 空调显示屏处显示收氟模式代码, 导风板呈水平送风位置, 室内机风机停止运行, 控制空调转制冷运行, 接着 关闭第二电磁阀 431 , 经过一定时间关闭第一电磁阀 43 , 最后整机关机(转 制冷运行后的控制方式同制冷状态)。 或者丙烷探测器检测制冷剂浓度超标, 报警器报警, 空调显示屏处显示故障代码, 导风板呈水平送风位置, 室内机 继续运行(优选是高风档运行), 控制空调转制冷运行 t3 时间后, 接着关闭 第二电磁阀 431 , 经过 tl 时间关闭第一电磁阀 43 , 在经过 t2后, 最后整机 关机, 停止压缩机和室内机风机(转制冷运行后的控制方式同制冷状态)。 当丙烷探测器检测到有制冷剂泄露时, 空调室内机控制器增加该故障掉 电记忆功能, 该功能为不可恢复, 可用遥控器组合键清除故障。 其中, 在空调器处于收氟模式期间, 遥控器不能执行开机操作。 从以上的描述中, 可以看出, 本发明上述的实施例能够减少或者进而防 止室内机侧残留制冷剂, 进而很好地提高空调器的安全性。 通过釆用上述的方案, 空调器关机时, 能够对室内侧冷媒进行回收, 可 将至少 95%的制冷剂回收至室外侧, 空调器不工作时室内侧残留的制冷剂微 乎其啟, 从而达到期望的目的。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护 范围之内。
