Kuwongolera kwa Compressor popanga mpweya wabwino komanso zowongolera mpweya

Kuwongolera liwiro losinthika la chiller kumakupatsani mwayi wowongolera kupanikizika kosalekeza ndikufananiza kuchuluka kwa chosowa chenicheni kutengera miyeso mu dongosolo. Kuwongolera liwiro kumakhala kopindulitsa ngati kompresa imayenda kwa nthawi yayitali pakulemedwa pang'ono. Chepetsani ndalama zogwirira ntchito poyendetsa mapulogalamu pa liwiro lotsika zomwe zimachepetsa kugwiritsa ntchito mphamvu. Ndipo chepetsani ndalama zoyikapo pakukhathamiritsa dongosolo ndi kompresa yokha.

Magalimoto a Danfoss AC amawonetsetsa kuti zoyambira zochepa ndi kuyima zimachepetsa kuvala kwamakina. Ndipo mawonekedwe odzipatulira, monga ntchito ya 'skip resonance', amakulolani kuti muzindikire mosavuta ma frequency kuti muteteze phokoso ndi kuwonongeka.

Zogulitsa zama compressor zimaphatikizapo zoyambira zofewa, zoyendetsa zamphamvu kwambiri, ma drive otsika a harmonic, zosefera za AHF. Ma drive onse amaperekedwa ndi njira zowongolera za cascade, ma coil a DC ndi owongolera a PID.

Chimodzi mwazinthu zotsika mtengo kwambiri pamayendedwe ozizirira ndi mphamvu. Pazinthu zambiri zoziziritsa ndi zoziziritsa kukhosi, mphamvu imaposa kutentha kwanyengo chifukwa cha kusiyanasiyana kwa nyengo, kukweza kwazinthu, kusiyanasiyana kwazomwe zimakhalapo, ndi zida zamagetsi zomwe zimapangitsa kuti magetsi awonongeke. Ma driver amakono, odzipatulira a AC amasinthasintha mosalekeza kuchuluka kwa zida kutengera kutentha komwe kumafunikira komanso zofunikira. Zopindulitsa zake ndizochepa kwambiri zogwiritsira ntchito mphamvu komanso kuchepetsa ntchito ndi kukonza ndalama.

Compressor wanzeru ndi condenser/evaporator fan kuwongolera ndikofunikira munjira iliyonse yozizirira bwino kapena firiji. Mutha kupulumutsa 10-25% pakugwiritsa ntchito mphamvu pogwiritsa ntchito ma drive a Danfoss AC kuti muwongolere mphamvu ya ma compressor a firiji, ma condensers ndi ma evaporator. Pakupanga kukhazikika ndikulinganiza kuchuluka kwa katundu weniweni, dongosolo lonse la machitidwe (COP) limathandizira kupereka mphamvu zopulumutsa mphamvu.

Cascade control imathandizira kupulumutsa mphamvu ndikuchepetsa mtengo wamoyo

Kukonzekera kwa Cascade kumapangitsa kuti pakhale kuyanjana koyenera pakati pa pulogalamu ndi drive ya AC potsitsa pang'ono. Kuyika kwapansi kumayendetsedwa ndi ntchito imodzi, monga compressor, yoyendetsedwa ndi galimoto. Kutentha kukakwera, kuyendetsa kumayamba ma compressor owonjezera amodzi panthawi. Izi zimatsimikizira kuti mapulogalamuwa amagwira ntchito bwino kwambiri, ndipo galimotoyo imakhala ndi mphamvu zambiri pamagetsi onse.

Kuwongolera bwino kwa cascade kumatsimikiziranso kuvala kochepa pamapulogalamu omwewo. Pogwiritsa ntchito ma compressor oyendetsedwa ndi mains-powered, mwachitsanzo, oyang'anira kukonza amatha kuonetsetsa kuti aliyense atha kukhala ndi maola ogwirira ntchito ofanana komanso mulingo wofanana wovala. Izi zimawonjezera moyo wa ntchito ndikuwonjezera nthawi yantchito ndikuchepetsa mtengo wanthawi zonse.

Danfoss Drives 'Advanced Multi-zone pack controller imawonetsetsa kuyenda bwino ndikuwongolera mpaka mapaketi asanu ndi limodzi a kompresa. Izi zimachepetsa kugwiritsa ntchito mphamvu, zimapewa kusuntha pafupipafupi komanso kutsika, kukhazikika kupsinjika ndi kutentha, komanso kumachepetsa kung'ambika kwa kompresa. Mofananamo, Pump Cascade Controller imagawira maola othamanga mofanana pamapampu onse kuti asamawonongeke pamapampu amtundu uliwonse.
