Description

一种解决空调制冷时压缩机内置保护器跳机的控制系统
技术领域
本发明涉及一种解决空调制冷时压缩机内置保护器跳机的控制系统。
背景技术
随着房价的日益升高，房地产开发商对空调外机位的面积也越缩越小，导致空调外机位散热空间小，特别是对于定频空调，频率无法调节，高环温制冷运行，容易出现压缩机内置保护器断开而引起停机，尤其在室外机脏堵或安装位置有格栅情况下，更是会引起频繁跳机，一旦压缩机内置保护器断开，短则半小时，长则一小时才能自动恢复，空调无法正常使用。
发明内容
针对上述问题，本发明提供了一种解决空调制冷时压缩机内置保护器跳机的控制系统，有效解决了背景技术中指出的问题。
本发明采用的技术方案是：
一种解决空调制冷时压缩机内置保护器跳机的控制系统，包括以下步骤：
1)在进行制冷压缩机启动时，根据不同的室外环境温度来选择刚开机时室内机风机的风档：当Tao≥48℃时，室内机风机不启动；当48℃＞Tao≥43℃时，室内机风机以低风档启动；当Tao＜43℃时，室内机风机以高风档启动，接着运行3min，并在3min内进行风挡升档控制，并在3min后控制室内机风机按照设定风档运行；
2)压缩机运行3分钟后，根据排气温度来自动调节室内机风机的风档：若连续3次出现Tdn-Tdn-1＞0且Td≥110℃，则室内机风档在当前风档基础上每30s减1档，直到Td≤95℃或室内机风档停机，并维持3min，在该3min内进行风档升档控制，3min后控制室内机风机按照设定风档运行。
作为优选，所述的风挡升档控制包括以下步骤：若连续3次出现Tdn-Tdn-1＜0且Td＜70℃，则室内机风档在当前风档基础上每30s增加1档，直到连续3次出现Tdn-Tdn-1≥0或室内机风档增加到最高档，则室内机风档维持当前风档。
定频空调高环境温度制冷时主要在压缩机刚启动和运行过程中会出现压缩机内置保护器断开的情况，压缩机内置保护器断开主要受排气温度和压缩机电流双重影响，即排气温度过高或压缩机电流过大，都会导致内置保护器断开；同时排气温度和压缩机电流之间又存在反向关系，即排气温度高时，压缩机允许承载的电流小，排气温度低时，压缩机允许承载的电流大，本发明通过在高环境温度时降低排气温度值来提高压缩机所能承受的电流，从而解决内置保护器断开问题。
本发明通过控制逻辑的优化来解决定频空调高环温制冷时压缩机内置保护器跳机问题，无实际成本增加；解决了传统定频空调高温制冷时压缩机内置保护器断开后，长时间内无法继续时候的问题。
具体实施方式
下面通过具体的实施例对本发明做进一步的详细描述。
一种解决空调制冷时压缩机内置保护器跳机的控制系统，包括以下步骤：
1)在进行制冷压缩机启动时，根据不同的室外环境温度来选择刚开机时室内机风机的风档：当Tao≥48℃时，室内机风机不启动；当48℃＞Tao≥43℃时，室内机风机以低风档启动；当Tao＜43℃时，室内机风机以高风档启动；
接着运行3min，并在3min内进行风挡升档控制：若连续3次出现Tdn-Tdn-1＜0且Td＜70℃，则室内机风档在当前风档基础上每30s增加1档，直到连续3次出现Tdn-Tdn-1≥0或室内机风档增加到最高档，则室内机风档维持当前风档；
3min后控制室内机风机按照设定风档运行；
2)压缩机运行3分钟后，根据排气温度来自动调节室内机风机的风档：若连续3次出现Tdn-Tdn-1＞0且Td≥110℃，则室内机风档在当前风档基础上每30s减1档，直到Td≤95℃或室内机风档停机，并维持3min，在该3min内进行风档升档控制：若连续3次出现Tdn-Tdn-1＜0且Td＜70℃，则室内机风档在当前风档基础上每30s增加1档，直到连续3次出现Tdn-Tdn-1≥0或室内机风档增加到最高档，则室内机风档维持当前风档；
3min后控制室内机风机按照设定风档运行。
其中：Tao为室外环境温度，Td为排气温度，Tdn为当前排气温度，Tdn-1为前一次排气温度。
最后，需要注意的是，以上列举的仅是本发明的具体实施方式。显然，本发明不限于以上实施方式，还可以有很多变形。本领域的普通技术人员能从本发明公开的内容中直接导出或联想到的所有变形，均应认为是本发明的保护范围。
