 机壳温度过低的影响及原因

机壳表面温度低于正常范围，其原因是吸气温度太低（低于15OC）。它对冷冻油和电动机绕组的冷却都有利，但制冷量有所下降。当吸气温度特别低时，会使大半只机壳结露，就有液击的危险，这是对压缩机的致命打击，应特别注意。同时冷冻油内溶解大量的制冷剂，不利于运动零件的润滑。

（3） 凝器的温度状况

1） 冷凝器的温度状况

正常情况是，前半部散热管很热，且其温度有缓慢缓慢的逐步下降的均势。后半部散热管的热感程度与前半部相比有较大的降低，这是由于后半部管内制冷剂已逐步液化，已达到冷凝温度和过冷温度。当不正常情况产生时，一种是前半部不太热，后半部接近常温（环境温度），其原因是压缩机吸信湿蒸汽制冷剂时或制冷剂量不足。另一种是整个冷凝管都很热，其原因是制冷剂量过多或通风量小，或环境温度高。

2） 水冷冷凝器

The effect and cause of the case temperature is too low

The surface temperature of the casing is below the normal range because the suction temperature is too low (less than 15 OC). It is good for cooling both the refrigeration oil and the motor windings, but the cooling capacity is reduced. When the inhalation temperature is extremely low, most of the casing will be dew condensation, and there is a danger of liquid hammer. This is a fatal blow to the compressor, and special attention should be paid. At the same time, a large amount of refrigerant is dissolved in the frozen oil, which is not conducive to the lubrication of moving parts.

(3) Temperature condition of the condenser

1) Temperature condition of the condenser

Normally, the first half of the heat pipe is very hot, and its temperature has a slow and slow gradual decline in the balance. The thermal sensitivity of the rear half of the heat pipe is greatly reduced compared with the first half. This is because the refrigerant in the second half of the pipe has gradually liquefied and has reached the condensation temperature and the supercooling temperature. When an abnormal situation occurs, one is that the first half is not too hot, and the second half is close to normal temperature (ambient temperature) because the compressor sucks the wet steam refrigerant or the refrigerant amount is insufficient. The other is that the entire condenser is very hot due to excessive refrigerant charge or low ventilation, or high ambient temperature.
