Abstract

本发明涉及一种基于盘管温度风机补偿的热泵热水风机控制方法，其特点是包括以下步骤：步骤一、热泵的压缩机启动并且连续稳定运行，开启直流风机的动态补偿判定逻辑；步骤二、预设工况阈值：包括盘管温度正常工况阈值A、盘管温度紧急补偿阈值B，且满足B＜A；步骤三、实时采集盘管温度数据：盘管温度是T3，盘管的实时温度是T3n，盘管的上一检测周期温度是T3(n‑1)，盘管温度周期变化阈值是ΔT3；依据盘管温度实时工况执行以下对应控制逻辑：其优点是解决定频主板搭配直流电机系统的控制痛点，可适配不同环境温度与安装工况，实现对风机运行的提前干预与精准调节，有效降低系统运行波动，保障热泵热水系统的稳定运行与可靠性。
