Description
技术领域
本发明涉及一种复式空调,特别涉及一种复式空调的通信系统及其方法。
背景技术
一般,空调是一种用于控制室内空气的温度、湿度、气流和洁净度以提供舒适的室内环境的设备。根据空调单元的结构,将空调分为整体式空调和分体式空调,其中,整体式空调将室内单元和室外单元都包含于一个箱体中,而分体式空调则将作为室外单元的冷凝器和作为室内单元的蒸发器分别安装在不同的空间。
分体式空调包括空气制冷且制热的空调,其可通过利用流路转换阀转换制冷剂的流路而选择性地实现空气制冷功能和制热功能。
近来,具有可在每个室内空间进行空气制冷或制热的多个室内单元的复式(multi-type)空调被越来越多地使用。对于这种复式空调,多个室外单元并行连接,以便适当处理室内单元的运行负载,其中每个室外单元具有多个压缩机。
图1示出了根据传统技术的复式空调的室外单元的结构。
如图1所示,传统的复式空调包括第1到第n个室外单元11a~11n以及多个室内单元(未示出)。
多个室外单元11a~11n包括一对第一和第二压缩机13a和13b、用于转换制冷剂流路的四通阀21、用于交换制冷剂的热量的室外热交换器25以及用于向第一和第二压缩机13a和13b提供气态制冷剂的收集器27。
在第一和第二压缩机13a和13b的上部设有用于排放制冷剂的排放管15,并且在第一和第二压缩机13a和13b的各下部连接有用于吸入制冷剂的吸入管17。吸入管17的一侧连接收集器27。在第一和第二压缩机13a和13b之间连接有与第一和第二压缩机13a和13b连通油平衡管19,其用于对第一和第二压缩机13a和13b均匀供油。
在第一和第二压缩机13a和13b的排放侧设有油分离器31和止回阀33,并且在第一和第二压缩机13a和13b的吸入侧形成回油路35以将分离的油返回到第一和第二压缩机13a和13b。
在止回阀33的下侧设有用于转换制冷剂流路的四通阀21,并且室外热交换器25与四通阀21的第一阀口连接。收集器27与四通阀21的第二阀口连接,并且与室内单元连接的连接管41与四通阀21的第三阀口连接。
在室外热交换器25沿制冷剂流动方向的一侧设有接收器(receiver)37,并在接收器37的一侧和连接管41的一侧均设有检修阀43a和43b。检修阀43a和43b的一侧分别连接到与室外单元11a~11n连接的主制冷剂管45。
传统的复式空调被构造为由固定线路连接多个室外单元(第1到第N辅室外单元和主室外单元)和多个室内单元(第1到第M室内单元)。
图2是示出由固定线路连接多个室外单元(第1到第N辅室外单元和主室外单元)和多个室内单元(第1到第M室内单元)的状态的示意图。
如图2所示,由固定线路连接多个室外单元(第1辅室外单元到第N辅室外单元和主室外单元)和多个室内单元(第1到第M室内单元)以进行有线通信。多个室外单元(第1辅室外单元到第N辅室外单元和主室外单元)之一作为中央控制器,其用于控制多个室外单元和多个室内单元,作为中央控制器操作的室外单元称为主室外单元,其他的室外单元称为辅室外单元。
主室外单元控制辅室外单元(第1到第N辅室外单元)、多个室内单元(第1到第M室内单元)及其本身。由固定线路连接的主室外单元和辅室外单元通过固定线路串行通信彼此通信,并且主室外单元与多个室内单元(第1到第M室内单元)也通过固定线路串行通信彼此通信。即,复式空调包含固定线路通信系统。此处,多个室外单元(第1辅室外单元到第N辅室外单元和主室外单元)和多个室内单元(第1到第M室内单元)使用的固定线路串行通信为UART(通用异步收发器)串行通信,其最大速率为4800bps。
因而,在传统的复式空调的通信系统中,因为由固定线路彼此连接的多个室外单元和多个室内单元通过固定线路串行通信发送和接收数据,所以当安装多个室外单元和多个室内单元的通信线路时,通信线路可能会错误地连接或断开连接,从而引起故障。
发明内容
因此,本发明的目的是提供一种复式空调的通信系统及其方法,其能够通过使多个室外单元和多个室内单元无线发送和接收数据而增强数据通信的可靠性。
为实现这些及其他优点,根据本发明的目的,如在此实施和广泛说明的,本发明提供一种复式空调的通信系统,包括:主室外单元,其用于向多个辅室外单元无线且直接地发送数据,和/或无线且直接地接收来自多个辅室外单元的数据;室外中继单元,其用于通过固定线路串行通信方法与该主室外单元通信;室内中继单元,其用于通过局域通信网络或固定线路与该室外中继单元通信;以及多个室内单元,其用于与该室内中继单元无线通信。
为实现上述目的,本发明还提供一种复式空调的通信方法,包括:多个辅室外单元和主室外单元无线且直接地发送和/或接收数据;通过固定线路串行通信向室外中继单元发送该主室外单元的数据;该室外中继单元接收发送的数据,并通过局域通信网络或固定线路将接收的数据发送到室内中继单元;以及该室内中继单元将通过该局域通信网络或固定线路接收的数据无线发送到多个室内单元。
为实现上述目的,本发明还提供一种复式空调的通信方法,包括:多个室内单元无线发送数据;室内中继单元无线接收所述数据;该室内中继单元通过局域通信网络或固定线路将接收的数据发送到室外中继单元;以及该室外中继单元通过固定线路将所述接收的数据发送到主室外单元。
与现有技术相比,本发明的优点在于能够通过使多个室外单元和多个室内单元无线发送和接收数据而增强数据通信的可靠性。
通过下面对本发明的详细说明并结合附图,本发明的上述和其他目的、特征、方案和优点将会变得更明显。

在附图中:
图1是示出根据传统技术的复式空调的室外单元的结构的示意图;
图2是示出根据传统技术的图1中复式空调的通信系统的结构的示意图;
图3是示出根据本发明的复式空调的通信系统的结构的示意图;

图5是在根据本发明的复式空调中主室外单元接收来自多个室内单元的数据的流程图。
具体实施方式
现在,将参考图3到图5说明根据本发明优选实施例的复式空调的通信系统,其能够通过使多个室外单元和多个室内单元无线发送和接收数据而增强数据通信的可靠性。
图3是示出根据本发明的复式空调的通信系统的结构的示意图。
如图3所示,复式空调的通信系统包括:多个辅室外单元;主室外单元,用于向多个辅室外单元无线发送数据并接收来自多个辅室外单元的数据;室外中继单元(outdoor relay unit),用于通过固定线路串行通信方法与主室外单元通信;室内中继单元,用于通过局域通信网络或固定线路与室外中继单元通信;以及多个室内单元,用于与室内中继单元无线通信。
现在将参考图4和图5说明根据本发明的复式空调的通信系统的操作。
根据本发明的复式空调的通信系统的操作可分为:主室外单元向多个辅室外单元和多个室内单元发送数据(例如控制命令)的方法;以及主室外单元接收来自多个辅室外单元和多个室内单元的数据(例如室外温度、室内温度等)的方法。
首先,参考图4说明在复式空调的通信系统中主室外单元向多个辅室外单元和多个室内单元发送数据的方法。
图4是在根据本发明的复式空调的通信系统中主室外单元向多个辅室外单元和多个室内单元发送数据的流程图。
如图4所示,在复式空调的通信系统中,主室外单元向多个室内单元发送数据的过程包括:在多个辅室外单元与主室外单元之间无线发送和/或接收数据(步骤S41);通过固定线路串行通信将主室外单元的数据发送到室外中继单元(步骤S42);室外中继单元接收数据并且通过局域通信网络或固定线路将接收的数据发送到室内中继单元(步骤S43);以及室内中继单元将通过局域通信网络或固定线路将接收的数据发送到多个室内单元(步骤S44)。
下面将详细说明主室外单元向多个辅室外单元和多个室内单元发送数据的方法。
多个辅室外单元,即第1到第N辅室外单元(SO1、SO2、……、SON),分别通过其自己的无线通信单元,即第一辅无线通信单元、第二辅无线通信单元、……、第N辅无线通信单元(SO1-1、SO2-1、……、SON-1)向主室外单元31发送作为在无线通信中使用的数据格式的数据(例如室外温度),并且主室外单元31通过其无线通信单元,即主无线通信单元31-1将数据(例如控制命令)以无线通信数据格式发送到多个辅室外单元(SO1、SO2、……、SON)(步骤S41).这种情况下,通过无线通信单元进行多个辅室外单元(SO1、SO2、……、SON)与主室外单元31之间的通信.从而,如上所述,多个辅室外单元(SO1、SO2、……、SON)和主室外单元31分别包含有无线通信单元.
主室外单元31通过固定线路串行通信向室外中继单元32发送其数据(例如用于控制多个室内单元的命令)(步骤S42)。
室外中继单元32一旦接收到数据,就将接收的数据转换为网络中使用的数据(后面称为“网络数据”),并通过局域通信网络或固定线路将转换的数据(网络数据)发送到室内中继单元33(步骤S43)。这种情况下,优选地,室内中继单元33和室外中继单元32通过串行电缆连接,并且,优选地,局域通信网络为以太网。
室内中继单元33将接收的网络数据转换为无线通信数据,并通过其无线通信单元(室内无线通信单元)33-1而将转换的无线通信数据发送到多个室内单元,即第一室内单元、第二室内单元、……、第M室内单元(SI1、SI2、……、SIM)(步骤S44)。
现在,将参考图5说明在复式空调的通信系统中主室外单元接收来自多个室内单元的数据的方法。
图5是在根据本发明的复式空调中主室外单元接收来自多个室内单元的数据的流程图。
如图5所示,主室外单元接收来自多个室内单元的数据的过程包括:多个室内单元无线发送数据(步骤S51);室内中继单元无线接收数据(步骤S52);室内中继单元通过局域通信网络或固定线路将接收的数据发送到室外中继单元(步骤S53);以及室外中继单元通过固定线路将接收的数据发送到主室外单元(步骤S54)。
多个室内单元,即第1到第M室内单元(SI1~SIM),通过其无线通信单元,即第1到第M无线通信单元(SI1-1~SIM-1),以无线通信数据格式将其数据(例如室内温度、用户的期望温度等)发送到室内中继单元33(步骤S51)。这种情况下,多个室内单元(SI1~SIM)与室内中继单元33通过无线通信单元通信。从而,如上所述,多个室内单元(SI1~SIM)和室内中继单元33分别包含无线通信单元。
室内中继单元33接收发送的无线通信数据,并将其转换为网络数据的格式(步骤S52)。
然后,室内中继单元33通过局域通信网络或固定线路将转换的数据(网络数据)发送到室外中继单元32(步骤S53)。这种情况下,优选地,室内中继单元33和室外中继单元32由串行电缆连接,并且,优选地,局域通信网络为以太网。
室外中继单元32将接收的数据(网络数据)转换为无线通信数据,并通过固定线路将转换的无线通信数据发送到主室外单元31(步骤S54)。
在本发明的一个实施例中,上述无线通信单元形成为蓝牙通信模块,该单元将各种数据转换为蓝牙通信数据并发送,以及接收蓝牙通信数据并将其转换为无线通信数据。在本发明的另一实施例中,无线通信单元形成为RF通信模块,其将各种数据转换为RF通信数据并发送,接收RF通信数据并将其转换为无线通信数据。
优选地,主室外单元31和多个室内单元(SI1~SIM)通过无线通信单元彼此直接无线连接.然而,由于安装在房屋外侧的主室外单元32与安装在房屋内侧的多个室内单元(SI1~SIM)之间的诸如墙壁之类的障碍物,所以直接使用诸如蓝牙通信模块的通信模块还存在困难,例如数据通信错误.因此,在本发明中,使用中继单元例如室外中继单元和室内中继单元,从而减少在主室外单元与多个室内单元间进行数据通信过程中发生的错误.然而,就此而言,如果诸如蓝牙通信的局域无线通信能够克服诸如墙壁之类的障碍物的影响,则主室外单元和多个室内单元无需使用这种中继单元就可彼此进行无线通信.
如上所述,复式空调的通信系统的优点为:因为多个室外单元和多个室内单元可通过无线通信发送和/或接收数据,从而能够增强数据通信的可靠性。
由于本发明可在不脱离其精神或本质特征的情况下以多种形式实施,因而也应认为上述的实施例并未由前述说明的任何细节所限定,除非特别说明,应在附加的权利要求书限定的精神和范围内进行广泛地解释,因而,落入权利要求范围内或该范围的等效物内的所有变化和修改都将含盖于附加的权利要求书中。
