空调系统的控制方法和控制系统
摘要：
本发明提供了一种空调系统的控制方法和控制系统，包括：根据工作的室内机或室外机的参数判断所述空调系统是否缺少冷媒；若是，判断所述空调系统是否存在不工作的室外机；若存在，控制不工作的室外机的第一电磁阀和第二电磁阀打开，控制工作的室外机的第二电子膨胀阀和第二电磁阀打开；若不存在，判断所述空调系统是否存在不工作的室内机；若存在，控制所述不工作的室内机的电子膨胀阀打开；若不存在，控制所述空调系统发出缺少冷媒的警报，从而解决了由于冷媒堆积在不工作的室内机和室外机中而造成的空调系统缺少冷媒的问题，有效提高了压缩机的可靠性，确保了空调系统的可靠运行。
摘要（英）：

The invention provides a control method and a control system of an air conditioning system. The control method comprises the steps of: judging if the air conditioning system is short of refrigerants according to parameters of a working indoor unit or outdoor unit; if so, judging if the air conditioning system has an idle outdoor unit; if so, controlling a first electromagnetic valve and a second electromagnetic valve of the idle outdoor unit to be opened, and controlling a second electronic expansion valve and a second electromagnetic valve of the working outdoor unit to be opened; if not, judging if the air conditioning system has an idle indoor unit; if so, controlling an electronic expansion valve of the idle indoor unit to be opened; and if not, controlling the air conditioning system to give an alarm of lacking refrigerants, so that the problem of shortage of the refrigerants in the air conditioning system due to accumulation of the refrigerants in the idle indoor unit and outdoor unit is solved, the reliability of the compressor is effectively improved, and the reliable operation of the air conditioning system is guaranteed.
