The Reasons of Frosting on Ultra low Temperature Recirculating Chillers
Frosting will appear when many users take advantage of ultra low temperature recirculating chillers, while some are not. It is confusing and whether it is relevant to refrigeration.First of all, why does ultra low temperature recirculating chillers frost? To sort it out, we can turn our eyes on the reasons of direct-cooling ultra low temperature recirculating chillers. The frost is a white crystal of vapour which will congeal on the surface of ultra low temperature objects.The air will frost ...
Visualizza dettagliThe Noise Analysis of Precision Chiller
Generally speaking, even the most sophisticated refrigerating equipment will also have some trouble when used for a long time. If the noises present in the precision chiller after prolonged use, I am sure that it appears some faults. So let's go deeper to see where these noises are from.The noise of compressorThe compressor is in the core position of the inner structure of the precision chiller. In general, compressors include screw and stroll, you can pick up one as what you need. Once the c...

The effective operation of low temperature freezer is relevant to the needed refrigerating effect. It is crucial to correct expansion valve if better cooling effect is wanted. So, how to debug the expansion valve of low temperature freezer?During the operation of low temperature freezer, the smaller the opening is, the less the volume of fluid transmission and pressure are,and vice versa. Based on the thermodynamic property of refrigerating fluid, the corresponding temperature varies as the p...

Spiegazione dettagliata dell'attenzione al debug del sistema di raffreddamento a circolazione chiusa
La preparazione del sistema di raffreddamento a circolazione chiusa prima della messa in servizio è una parte importante del processo di debug, che può influenzare l'andamento dell'intero processo di debug. In generale, occorre prestare attenzione al rilevamento delle perdite del sistema di tubazioni dell'aria del sistema di raffreddamento a circolazione chiusa e alle perdite del sistema di raffreddamento a circolazione chiusa. Esistono regolamenti dettagliati per la quantità, che sono approssimativamente divisi in sistemi ad alta, media e bassa pressione. In base alle diverse...

Guasto al compressore del sistema di controllo della refrigerazione causato dalla pressione dell'olio
Se non c'è pressione dell'olio nel sistema di controllo della refrigerazione, controllare il collegamento del sistema di tubazioni della pompa dell'olio per verificare che non ci siano perdite d'olio o blocchi. Se il collegamento è allentato, è necessario stringere il giunto. Se è ostruito, è necessario liberare la conduttura dell'olio. Verificare quindi se il compressore del sistema di controllo della refrigerazione è troppo grande a causa dell'apertura della valvola di regolazione della pressione dell'olio o se il nucleo della valvola è staccato. Se la valvola di regolazione della pressione idraulica del sistema di controllo...

Discriminazione del sistema di test di integrazione delle batterie di potenza
Using the degree of superheat to judge whether the opening degree of the integrated test system of the power battery is appropriate, and using a thermometer to measure the difference between the temperature of the return pipe and the evaporating temperature (ie, the actual superheat) and the standard superheat (between 5-8 ° C) Check to see if the adjustment is appropriate. Using the suction pressure of the compressor as the saturation pressure in the evaporator, the table looks for an approx...

The reason why the cooling water circulator needs the main water circulation
The supplement of the water cycle is directed to a water-cooled cooling water circulator, and the air-cooled cooling water circulator does not have this problem. The water-cooled cooling water circulator needs cooling water during normal operation. The cooling circulating water is the most important part of the whole water-cooled cooling water circulator. However, the water-cooling system of the water-cooled cooling water circulator is in the process of normal operation. What is the main reas...
