Četiri su razloga za blokadu rashladnog sistema nisko{0}}zamrzivača: začepljenje krhotina, začepljenje leda, loš elektromagnetni ventil, loš ekspanzioni ventil, itd.
1. Blokada krhotina: Jerrashladni sistem hladnjaka has strict requirements in all aspects of production and manufacturing, it is necessary to ensure that each link must be cleaned. However, at present, most chiller manufacturers purchase components and then assemble them, so it is inevitable that some systems will be impure, and in severe cases, system blockage will occur. Generally, blockage occurs at the entrance of the filter or expansion valve. Therefore, chiller (freezer) manufacturers have installed "filters" in the refrigeration system to filter out impurities in the system. When the impurities in the pipes of the refrigeration system accumulate to a certain extent, the filter will be blocked, which will affect the refrigerant throughput of the system, and in severe cases, low-pressure failure will occur.
If the filter is clogged by a dirty system, it will only cause the cooling capacity of the device to drop slightly, and you may not even feel the impact. When the "filter" is slightly blocked, there will be a temperature difference between the inlet and outlet of the "filter", which can be felt by holding the inlet and outlet by hand. In severe cases, condensation or frost will appear on the filter. If condensation or frost occurs on the filter (when the machine is running, condensation does not count when the machine is stopped), it can be judged that the filter is blocked. At this time, just replace the filter of the same type.
2. Blokada leda: U suštini, postoji vlaga u cevovodu sistema. Vlaga u sistemu teče sa rashladnim sredstvom do prigušnog ventila (ekspanzijskog ventila) nakon prigušivanja i ekspanzije, i formira stanje niske temperature i niskog pritiska na izlazu iz prigušnog ventila. Kada je temperatura isparavanja Kada je (temperatura prigušnog ventila) ispod tačke smrzavanja, vlaga u rashladnom sredstvu će ovde formirati kockice leda, koje će blokirati ventil za gas (ekspanzioni ventil) i uzrokovati kvar niskog pritiska. Na izlazu prigušnog ventila (ekspanzijskog ventila) dolazi do blokade leda.
It is not difficult to deal with this kind of problem. It is best to use a detachable filter first, which is equipped with "calcium chloride" to thoroughly filter the water in the system for many times, and then replace it with a disposable filter of the same type. device.
3. Elektromagnetni ventil je pokvaren: elektromagnetni ventil je nezamjenjiv dodatak u rashladnom sistemu i ima funkciju zaštite sigurnosti sistema (kada kompresor prestane da radi, rashladno sredstvo se prekida, a rashladno sredstvo ne nastavlja da radi protok u isparivač.U memoriji postoji velika količina rashladnog sredstva, kada se kompresor sljedeći put ponovo pokrene, lako je izazvati tečni udar na ploči ventila kompresora i oštetiti kompresor). Kada je elektromagnetni ventil oštećen, protok rashladnog sredstva je blokiran, što dovodi do kvara niskog pritiska. Trenutno je većina proizvođača rashladnih uređaja izostavila elektromagnetne ventile kako bi smanjila troškove, ali to također ostavlja skrivene opasnosti za opremu.
4. Ekspanzioni ventil je oštećen: ekspanzioni ventil je jedna od četiri glavne komponente rashladnog sistema i nezaobilazna je komponenta. Ekspanzijski ventili se dijele na mehaničke ekspanzijske ventile i elektronske ekspanzijske ventile; Na mehanički ekspanzijski ventili utiču okolina tokom upotrebe. U nekim okruženjima korozivni gas će korodirati tečnost, uzrokujući korodiju ekspanzionog ventila. Većina njih je plin u paketu za mjerenje temperature ekspanzijskog ventila. Curenje (korozija spojne cijevi koja povezuje sijalicu sa tijelom ventila). Iako elektronski ekspanzioni ventil ima prednosti velikog raspona kontrole temperature i visoke preciznosti koju mehanički ekspanzioni ventil ne može nadmašiti, on ima nezavisan kontrolni sistem, koji takođe povećava stopu kvarova. Ako je ekspanzioni ventil oštećen, treba ga samo zamijeniti.
