Snow Ice Machine R404A Refrigeration Repair

Описание: Snow Ice Machine Not Cold Enough? | R404A Refrigeration Repair | Slushy Ice Problem Solved

Today we repaired a snow ice machine with a cooling problem.
The machine could not reach -20°C, causing the snow ice to come out strip-like instead of granular, affecting texture and quality.

Initial inspection showed:
✔ Machine starts normally
✔ Running current around 5.5A / 930W
✔ Uses R404A refrigerant
✔ Low-side pressure measured over 40 PSI, which is abnormally high
✔ Normal range should be 20–30 PSI

After detailed inspection, the root cause was found:
🔧 Capillary tube blockage
🔧 Improper factory installation caused restricted refrigerant flow
🔧 Resulting in insufficient cooling performance

Repair process included:
✔ Replacing the filter
✔ Nitrogen pressure test (no leaks detected)
✔ Vacuum process
✔ Recharging with R404A refrigerant

After repair:
✅ Temperature successfully reached -20°C
✅ Stable current around 5.5A
✅ Snow ice returned to proper granular texture

If your snow ice machine has issues like:
❌ Not cold enough
❌ Poor ice texture
❌ Abnormal refrigerant pressure

It may not be a compressor issue but a refrigeration system restriction.

雪花冰机温度降不下去？R404A 制冷系统维修实录

今天我们来维修一台 雪花冰机，故障是：
👉 制作雪花冰时 温度降不下去，无法达到 -20°C，
👉 原本应该是 颗粒状雪花冰，却变成 条状冰，口感明显变差。

现场检测发现：
✔ 机器可以正常启动
✔ 运行电流约 5.5A / 930W
✔ 使用 R404A 制冷剂
✔ 但系统低压高达 40+ PSI，明显高于正常的 20–30 PSI

进一步拆机检查后确认：
🔧 毛细管堵塞 是主因
🔧 原厂装配时毛细管插得太深，靠近过滤器
🔧 导致气流不顺、制冷效率不足

维修处理流程包括：
✔ 更换过滤器
✔ 充氮保压测试，确认无泄漏
✔ 抽真空
✔ 重新灌注 R404A 制冷剂

维修完成后再次测试：
✅ 温度成功下降至 -20°C
✅ 电流稳定在 5.5A 左右
✅ 雪花冰恢复 颗粒状，品质与口感正常

如果你的雪花冰机出现：
❌ 冰不够冷
❌ 雪花冰变条状
❌ 压力异常、制冷效果差

很大可能不是压缩机坏，而是 制冷系统细节问题。
