上海春普浅谈空调的吸气管、过滤器、冷凝器温度状况

发布时间:2018/7/2 11:09:54 浏览次数: 1101

通常,吸管感觉凉爽,有露水。在异常情况下,第一个原因是抽吸管太冷,露水过多,导致壳体大面积结露。其原因是制冷剂流量过大,液体不能在蒸发器中完全蒸发,存在液体回流现象。危险在于压缩机可能在湿冲程中运行。严重时,会产生液体冲击,阀片受到威胁。二、吸管不冷,不结露,外壳非常热。原因是制冷剂流量太小或冷却剂量不够。结果表明,排气温度升高,冷却能力下降。安徽塑胶跑道



基本情况与输液管相同,但有一个突出的异常现象,即,过滤器可能是凉的。原因是过滤网被污泥堵塞,过滤器不光滑。当制冷剂流动的过滤网中,有一个节流现象,即一部分液体汽化热,使过滤器冷却,严重遇露。另一种异常现象是过滤器不热,这相当于环境温度。原因是过滤网被完全堵塞,制冷剂不能流动。



冷凝器温度状况:正常情况下,上半部散热器管非常热,且其温度有缓慢缓慢的逐渐下降的平衡。与上半部相比,下半部的热灵敏度大大降低,这是由于制冷剂在管的后半部分逐渐液化,达到冷凝温度和过冷温度。当产生异常情况时,由于压缩机吸入湿蒸汽制冷剂或冷却剂量不足,在上半部不太热,而下半部分接近正常温度(环境温度)。另一种是由于冷凝液过多或通风量小或环境温度高,整个冷凝管非常热。



水冷式冷凝器:壳管式冷凝器壳在正常状态下是上部较热,下部较暖。在异常情况下,整个壳体不太热,因为冷却剂量不够。另一种情况是整个壳体由于冷却水不足或散热差(水管中的结垢)而非常热。在正常情况下,由于冷却水过小或散热差,外壳的外观非常热,另一个原因是整个外壳的外表面不太热,原因是冷却剂量不足。正常情况下,吸管感觉凉爽,有露水。其原因是冷凝器散热性差、冷凝温度过高或冷却剂量过大。安徽资质转让


Normally, the suction tube feels cool and has dew. Under abnormal circumstances, the first one is that the suction tube is too cold and dew is too much to cause the large area of the shell to dew. The reason is that the refrigerant flow is too large, the liquid can not be completely vaporized in the evaporator, and there is a liquid backflow phenomenon. The danger is that the compressor may run on wet stroke. When it is serious, it will produce liquid blow and the valve piece will be threatened. Two, the suction tube is not cold, no condensation, and the shell is very hot. The reason is that the refrigerant flow is too small or the cooling dose is not enough. The result is that the exhaust temperature rises and the cooling capacity decreases.

The basic situation is the same as the infusion tube, but it has a prominent abnormal phenomenon, that is, the filter may be cool. The reason is that the filter mesh is blocked by the sludge and the filter is not smooth. When the refrigerant flow filter network, there is a throttle phenomenon, that is, a part of the liquid vaporizing heat, making the filter cool, serious meeting Dew.  Another abnormal phenomenon is that the filter is not hot, which is equivalent to the ambient temperature. The reason is that the filter screen is completely blocked and the refrigerant can not flow. www.ahyaohui.com

Condenser temperature condition: normally, the first half of the radiator tube is very hot, and its temperature has slowly slow gradual decline of the balance. The heat sensitivity of the second half is greatly reduced compared with the first half, which is due to the gradual liquefaction of the refrigerant in the rear half of the tube, which has reached the condensation temperature and the supercooling temperature. When abnormal conditions are produced, one is not too hot in the first half, and the second half is close to the normal temperature (ambient temperature), because the compressor sucked the wet steam refrigerant or the cooling dose was insufficient. The other is that the whole condensing tube is very hot due to too much refrigerant or small ventilation or high ambient temperature.
Water cooled condenser: shell and tube condenser shell under normal condition is the upper part is relatively hot, the lower part is warm. Under abnormal conditions, the whole shell is not too hot, because the cooling dose is not enough. The other case is that the whole shell is very hot due to inadequate cooling water or poor heat dissipation (scaling in the water pipe).  Under normal conditions, the casing is very hot in appearance, because the cooling water is too small or the heat dissipation is poor; the other is that the outer surface of the whole casing is not too hot, and the reason is that the cooling dose is insufficient. Under normal circumstances, the suction tube feels cool and has dew. The reason is that the condenser has poor heat dissipation, high condensation temperature or too much cooling dose.
