The invention discloses a refrigerant leakage early warning system and method. The method comprises the following steps that temperature data and pressure data of an air conditioning unit are collected and preprocessed; calculating the refrigerant allowance by using the temperature data and the pressure data in combination with a physical property database; outputting an early warning signal according to the current refrigerant allowance, the leakage trend and the real-time leakage rate of the refrigerant; wherein the early warning signal comprises low-voltage early warning and remaining time for triggering the low-voltage early warning. The early warning method provided by the invention is high in calculation precision and reliable in data, and can monitor the stock of the refrigerant in the system and timely discover abnormal conditions without depending on big data or historical data; meanwhile, accurate early warning is achieved, system faults are avoided, and normal operation of the air conditioning unit is guaranteed; the system reliability is improved.

    本发明公开了一种制冷剂的泄露预警系统和预警方法,其中方法包括以下步骤:采集空调机组的温度数据和压力数据并进行预处理;利用温度数据和压力数据,并结合物性数据库计算制冷剂余量;根据当前制冷剂余量、泄露趋势和制冷剂的泄露实时速率输出预警信号;其中,所述预警信号包括:低压预警和触发低压预警的剩余时间。本发明提供的预警方法,计算精度高,数据可靠,且无需依赖大数据或历史数据,即可实现监测系统内制冷剂的存量,及时发现异常情况;同时实现准确预警,避免系统故障,保证空调机组的正常运行;提升系统可靠性。
