山东制冷机组冷风机降温缓慢与什么有关?

1.冷冻系统设计不合理时,冷冻油在蒸发器中残留,随着时间的增长,油的累积过多会严重影响制冷效果,应进行放油。如果蒸发器无其他故障,而蒸发管结霜稀稀拉拉不完整,既可判定为此类原因。
1. when the design of the refrigeration system is unreasonable, the frozen oil is retained in the evaporator. With the increase of time, the accumulation of oil will seriously affect the effect of refrigeration, and the oil should be carried out. If no other fault and the evaporator, evaporating pipe frost sparse incomplete, can be judged as such reasons.
2.冷库内货物堆积过多,负荷大。或货物摆放在风机送风风道,阻碍风机送风。
2. the accumulation of goods in the cold storage is too much, and the load is large. Or the cargo is placed in the blower air supply duct, which prevents the fan from blowing.
3.冷风机配置过小。

3. cold air blower is too small.

4.冷风机选型不对,导致化霜过于频繁;化霜周期过短或化霜时间过长;库温回温高。
4. fan selection right, resulting in frequent defrosting; defrost cycle is too short or the defrosting time; temperature to high temperature.
5.膨胀阀选型不对,或安装及调节不当。
5., the selection of expansion valve is incorrect, or improper installation and adjustment.
6.制冷剂充注过多或过少。
6. refrigerants are filled with too much or too little.
7.冷风机与冷凝机组连接管道过长,热损耗及热负荷过高。
7., the connection between the cold air compressor and the condensing unit is too long, and the heat loss and heat load are too high.
8.冷风机压力损耗较大时,考虑更换外平衡膨胀阀。
8., when the pressure loss of the cooling fan is large, consider the replacement of the external balance expansion valve.
9.观察冷风机电机有无反转现象;进、出管有无接反现象。
9. observe whether there is a reversal phenomenon in the cooling fan motor, and whether there is any connection between the inlet and outlet pipes.
