Dans le cadre d'une utilisation normale, le dispositif de refroidissement de test de la batterie doit être découvert à temps lorsqu'une anomalie se produit. Pour ce faire, il est nécessaire de bien comprendre la configuration de base du dispositif de refroidissement de test de batterie Chiller. La batterie...

Le battery test cooling device Chiller shell and tube condenser housing is normally the upper half is warmer and the lower half is warm. Under abnormal conditions, the entire housing is not too hot, and the original refrigerant amount is not enough. In another case, the entire housing is very hot due to insufficient cooling water or poor heat dissipation (scale in the water pipe). Under normal conditions, the casing condenser is very hot. The reason is that the cooling water is too small or the heat dissipation effect is poor. The other is that the outer surface of the casing is not too hot, because the refrigerant amount is insufficient.

Under normal circumstances, the battery test cooling device Chiller suction pipe feels cool and feels dew due to poor heat dissipation in the condenser, high condensation temperature or excessive refrigerant charge. Under normal conditions, the liquid tube is warm. Under abnormal conditions, the liquid tube is hot. The reason is that the condenser has poor heat dissipation, high condensation temperature or excessive refrigerant flow. Under normal conditions, the suction tube feels cool and feels dew. Under abnormal conditions, first, the suction pipe is cold and the dew is too much, so that the casing is exposed to a large area. The reason is that the refrigerant flow rate is too large, the liquid cannot be completely vaporized in the evaporator, and there is a liquid reflux phenomenon.

Battery test cooling device Chiller thermal expansion valve appearance temperature (including electronic expansion valve) Under normal circumstances, the lower half of the expansion valve body is very cool, and there is dew, the refrigerant flow is very dull. Under abnormal conditions, first, the valve body is relatively cold, the surface has more dew, and even frost, the refrigerant has a loud sound (gas flow). The reason is that the filter is blocked, or the refrigerant in the power box leaks, and the valve hole is closed. Under normal circumstances, the outer surface is very cold, and the condensation water drops continuously. The temperature of the inlet and outlet air is large, abnormal, the surface of the evaporator is not too cool, the dew is not much, or there is no condensation, and the refrigerant can be heard. The flowing sound is very loud, and the temperature difference between the inlet and outlet is small.

LNEYA battery test cooling device Chiller is equipped with brand accessories in the configuration, which has certain guarantees in safety and runs more smoothly and efficiently.

The above are the tips and instructions to be used during the use. You need to contact LNEYA when you need to know the device parameters or even the device video. Email address: sales@lneya.com
