Refrigerant kompresa. Refrigeration zida. Wononga refrigeration Compressors

Refrigeration kompresa - chipangizo kuti ndi udindo psinjika ndi ikukoka refrigerant nthunzi zipangizo zoyenerera. Inafalitsidwa mu mpweya ndi mayunitsi mafakitale. Koma nthawi zambiri ntchito mu mafakitale ndi refrigerators zii. Kwa chiwerengero cha makhalidwe a zida lagawidwa mitundu angapo.

Mtundu wa chipangizo

Mu gulu ili, pali magulu atatu. Choyamba ndi reciprocating kompresa wa unit refrigeration. Tiyeni tikambirane mwachidule mfundo za ntchito zake. The mafuta aggregates ngati wothinikizidwa kudzera pisitoni. Pamene iye akupita, ndi refrigerant akulowa mlengalenga ntchito ya kompresa lapansi. Pankhani kuchokera nthunzi makina. The makina refrigerant kompresa ali zoyendetsedwa ndi nkhani. Zikomo gawo ili ikuchitika pressurization. The mbale nyanga ali kutsogolo kompresa lapansi. Pakuti gawo ili pali zingalowe, kupereka makope coolant a dongosolo kuzirala. Centrifugal compressors, chillers ntchito ndi psinjika mpweya ndi mphamvu centrifugal. Izo analengedwa ndi kasinthasintha wa masamba impeller. Opanikizika refrigerant likulowerera mu diffuser ndi m'mene kuchepetsa mathamangidwe ake chifukwa otaya gawo kuwonjezeka. Izi zimachititsa kutembenuka mphamvu kayendedwe mu kuthekera, ndi ichi, nayenso, lili ndi kuwonjezeka kuthamanga mu dongosolo.

makhalidwe kusindikiza

Refrigeration zida Open mtundu lakonzedwa kuti galimoto magetsi ili kunja kwa nyumba ya. The galimoto olumikizidwa kwa kompresa mwachindunji kapena majeremusi. Mu wina theka-hermetic zida refrigeration anasonkhana. Compressors anayikidwa mu muli mu malo omwewo ndi galimoto magetsi. Pawiri amapezeka mwachindunji. Unit losindikizidwa lakonzedwa kuti galimoto ndi thupi, mwamphamvu anatsekedwa ndipo chimodzi-chidutswa.

Gawo ndi mtundu wa HIV

The tiyipukuse limagwirira kayendedwe rotational wa crankshaft ndi n'kukhala reciprocating zoyenda wa pisitoni lapansi. Pansi pa kusiyana kuthamanga amapezeka ingress mpweya mu m'chipinda. Pa kufika lowermost malo a pisitoni vavu kutseka imagwiridwa ndi dongosolo nkuyamba ndondomeko suction. Kompresa refrigeration wagawo akhoza opareshoni likuvutika limagwirira rocker. Izi wagawo ndalezo alipo. Mmenemo kayendedwe rotational ali reciprocating, ndiyeno mosinthanitsa. Mkati pali limagwirira rocker mwala kuyenda. Iwo okonzeka ndi rectilinear kapena arcuate kagawo.

Gawo ndi mtundu wa refrigerant

Refrigerant kompresa ungatithandizire ndi ammonia. pawiri Izi pansi psinjika adiabatic, kotero kuti kutentha ukufika 105 madigiri Celsius. khwekhwe Izi zimafuna zipangizo zina. Kuti izi mapeto, oyenera kuzirala jekete, umene kuchepetsa kutentha dongosolo. Machitidwe freon ntchito mpweya - freon. Pa psinjika kutentha ndi madigiri 45. Mu mayunitsi ambiri a mtundu wa ntchito ndi mpweya kuzirala.

gulu lina

Refrigerant kompresa malinga ndi dongosolo anasankha ntchito. The m'firiji mbale ndi zokolola mkulu, komanso nyumba ndi zipangizo angapo aggregates amenewa ntchito, imene dongosolo kufalitsa anaonetsetsa ndi mpope. Chifukwa yokakamiza otaya madzimadzi kudzera slab, dongosolo umenewu wabwino kutentha kutengerapo. Izi mosavuta amalola kukwaniritsa kugwedezekagwedezeka. Recirculation mpope njira amapereka nthawi yomweyo onse pa zida za yozizira koopsa. M'magulu sekondale brine wa mankhwala enaake kashiamu nthawi zambiri ntchito mu malo refrigerant kapena trichlorethylene. Chotero dongosolo amafuna ndalama ndi mkulu likulu Choncho, ntchito yake okha makhazikitsidwe sitimayo. Refrigerant kompresa mu wagawo ndi wokonzeka makope yokoka, limalola kothandiza ndiponso yaying'ono mufiriji ndi mtengo zofunika cha nthawi iyi ya yozizira koopsa. Wangwiro sing'anga ndi ntchito yapamwamba kachitidwe osakwatiwa-yozizira koopsa. Kuika wolandila wapakatikati angathe kukhala mwachindunji ndi mufiriji tiled. Cham'mbali mbale m'firiji mayunitsi zimafunika defrosting m'firiji matabwa kamodzi kapena kawiri pa tsiku. Kufunika ndi nakweza ngati woyendetsa Kodi Musakhetse madzi pa iwo. Koma pali njira ina. Chotero kapangidwe refrigeration wagawo ndi cholinga chowapatsa de A-icing kapena defrosting. Ngati mtundu uwu zipangizo zasungidwa mu mankhwala katoni ili ndi madzi, Ndi bwino kusamalira razmorzki ntchito. Mu mbale yopingasa, dongosolo zabwino, koma m'firiji ofukula mbale kukhalapo kwake ndi kuvomerezedwa. Kuchotsa midadada yomalizidwa ya zida amenewa m'pofunika kuti wakhala kale thawed.

Wononga refrigeration Compressors

Pakali pano, nthawi zambiri yozizira koopsa zipangizo yatenganso mafuta chodzaza mayunitsi izi mtundu. Kutayikira pakati awiri njira amachepetsa monga mafuta chakudya. Ubwino undoubted mayunitsi amenewa amaona kuti zitheka kuchepetsa phokoso.

Mfundo ntchito

Pamene wononga akuyamba atembenuza, ndiye pambali pa kuchoka kwa mano M'mimbamo pakati pawo pang'onopang'ono anamasulidwa ubwenziwu. Dongosololi akuyamba ku mapeto a suction. Matendawa, (cavities) chifukwa otsika kuthamanga awo odzazidwa boti kuti afika kumeneko ku chitoliro suction pawindo. Kamodzi pa mapeto osiyana M'mimbamo wa rotors ndi kwathunthu anamasulidwa mano ili mmenemo, M'mimbamo imafika suction buku la mtengo pazipita. Podutsa doko suction ndi sakukhudzidwa ndi cavities suction chipinda. The mafuta kufalitsidwa umaperekedwa kwa mbali ya nyumba kumene M'mimbamo pakati rotors chidatha kulankhula ndi mbali suction. Atangomva wamkazi ozungulira dzino adzapita mu M'mimbamo kutsogolera kusiya voliyumu ya malo wotanganidwa ndi mpweya. Motero, iwo adzakhala compress nthunzi ya. Zimenezi adzapitirira M'mimbamo mpaka mpweyawo mpaka akafika m'mphepete mwa doko kumaliseche.

wagawo mphamvu

Internal psinjika kompresa umenewu ndi wofunika nthawi zonse. Ndi ofanana ndi ulemu vuto yomaliza ya akutali kuthamanga ntchito chipinda pa nthawi zodula izo kwa chitoliro suction mu beseni chomwecho. Wononga kompresa isiyana pisitoni kuti iwowa ali okonzeka ndi valavu kudziletsa kuchita. Koma mu mtengo woyamba wa mkati nthunzi psinjika imasiyana malingana ndi kukula kwa doko kumaliseche. Ndi ofunika osati kukula, komanso malo. Kumaliseche kuthamanga - muyeso kumbali kumaliseche a kompresa lapansi. Mlingo zimadalira madzi kutentha, kuzirala condenser. Iwo ndi osiyana ndi kuthamanga mkati mwa psinjika a. Pamene mkati psinjika mlingo P1 amakhala poyerekeza ndi kumaliseche mbali P2 wa kompresa, ndiye ndi "vnegeometricheskoe compressing" nthunzi kuti zimatulutsa kuthamanga. Ngati M'malo mwake, izo ndi apamwamba kuposa p2, mpweya zambiri mu cavities a rotors ndi kuthamanga iyamba kugwera. Ntchito pa modes awa, kompresa ndi kunyeketsa mphamvu zambiri.
