Description

移动式空调及其控制方法
本申请要求2022年07月20日提交的、发明名称为“移动式空调及其控制方法”的中国专利申请CN 202210861220.8的优先权，上述中国专利申请的全部内容通过引用并入本申请中。

背景技术

S64、压缩机保持当前频率运行，下风机500以第二预设转速运行，上风机300以不低于第四预设转速的转速运行，然后进行步骤S4。其中，上风机300具体以第四预设转速的转速运行，第二预设转速大于第一预设转速，第二预设转速为居中的转速。其中上风机300以低速运转，可以向蒸发器100送风，蒸发器100吸收所送的风的热量，使蒸发器100处产生冷凝水。此时排气温度不高不低，冷凝器200温度也不高不低，冷凝器200需要一定程度的散热，这时下风机500以居中转速运行，可以保证对冷凝器200的散热，也可以保证下风机500的功率不会过高，减少耗电量。下风机500运行可以对冷凝器200进行散热，防止冷凝器200产生的热量流至蒸发器100处，影响蒸发器100生成冷凝水。
S65、压缩机降频运行，下风机500以第三预设转速运行，上风机300以不低于第四预设转速的转速运行，然后进行步骤S4。其中，上风机300具体以第四预设转速运行，第三预设转速大于第二预设转速，第三预设转速为下风机500的高转速。其中上风机300以低速运转，可以向蒸发器100送风，蒸发器100吸收所送的风的热量，使蒸发器100处产生冷凝水。此时排气温度过高，为了保护压缩机，防止压缩机跳机，要对压缩机进行降频。排气温度过高，会导致冷凝器200温度过高，需要对冷凝器200快速的散热，这时下风机500高速运行，可以快速地对冷凝器200散热，其可以防止冷凝器200产生的热量流至蒸发器100处，影响蒸发器100生成冷凝水。
S7、判断接水槽400的水位是否低至低水位，如果是，则进行步骤S8，如果否，则进行步骤S9。具体由控制器根据第二水位开关来 检测判断，接水槽400的水位低至低水位时，需要关闭水泵。
