The freezer have frost appears to handle in time
in freezers, freezer refrigeration way is divided into cold air cooled and direct, straight cold type of air-conditioner after using for a long time can produce frost imagine, because straight cold type of air-conditioner is on the lining of the refrigeration, the passage of time will produce in the lining of a layer of frost, if it is not clear in time, will be more and more thick, the serious influence of air-conditioner refrigeration, and increase power consumption.
Not only so, and when the cabinet put oneself in another's position inside the frost, can make the inside of the beverage wall stick, take not to come out.
When the evaporator frosting that would be much worse, to cause a decline in thermal resistance increased, heat transfer coefficient, so we should timely defrosting.
It can not only improve the air-conditioner refrigeration speed, and can better maintenance.
If you buy cold type of air-conditioner is straight, then consider the frosting processing.
When frost occurs, what people thinks of above all will is artificial defrosting method, this method is simple, the inside temperature effect is small, but the intensity of labor is big, defrost may be incomplete, and there are limitations.
There is water for frost, gas defrosting water through spray device to the evaporator spray melted the frost layer surface, and then through the drainage pipe, along with all the procedure is simple, high efficiency, incase temperature fluctuation is small, but water cream makes the service life of the lower cabinet.
This is normal defrosting method, is used by many customers used to, but are human, so if there are other methods?
In order to improve the effect of defrosting, of course, but also can save manpower, there will be other methods.
Below, and you do some introduction.
Electric defrost, hot electric heating element is used to analyse the commercial freezer to defrost.
System is simple, easy to operate, easy to realize automation, but power consumption.
Second hot gas defrosting, using the compressor discharge superheat steam, the condensing when gives off heat to melt double on the surface of the evaporator.
Its characteristic is high applicability, reasonable in terms of energy use, for ammonia refrigeration system, defrosting can also rushed out of the evaporator in the product oil at the same time, but the defrosting time is longer, has certain influence to the inside temperature, refrigeration system regulating station complex.
These methods currently on the market and is widely used to defrost, believe that everyone in the process of the use of air-conditioner, may find better methods of defrosting, can share out, and we study together and find a better way to convenient our life.
medical refrigerator has become a standardized way of dealing with industrial refrigerator.
Ningbo Jingeao Electronics INC. strives to reflect the highest ethical standards in our relationships with members, providers, and shareholders.
Ningbo Jingeao Electronics INC., a manufacturer of commercial refrigerators, might emphasize less hassle or less wasted time rather than emphasizing reliability or quality.
The commercial refrigerator outdoor fridge has significantly numerous benefits over other industrial refrigerator systems, which makes it first choice for commercial refrigerator.
It's the consistent experience that builds trust and loyalty. Creating a personality and platform that is scalable will allow you to evolve medical refrigerator with your consumers.
