Njira za firiji zimagwiritsa ntchito firiji ngati madzi ogwirira ntchito, ndipo mafiriji nthawi zambiri amakhala ndi mitundu iwiri: madzi ndi mpweya. Lero tikambirana za chidziwitso choyenera chokhudza madzi okwanira.
1. Kodi nthambi ya mufiriji kapena mpweya?
Kufalikira kwa Rifiniants Itha Kugawidwa m'magulu atatu: Chimodzimodzi firiji, osakanikirana osakanikirana ophatikizika, ndi a Azetropic adakanikirana.
Kuphatikizidwa kwa gawo limodzi lokhalokha sikusintha kaya kukhala kovuta kapena kwamadzi, kotero boma lingaimbe mlandu mukatha kuwongolera firiji.
Ngakhale kapangidwe ka mufiriji ya azetropic ndi kosiyana, chifukwa kuwirikiza kwa madzi ndi chimodzimodzi, kuphatikizika kwa mpweya ndi madzi alinso chimodzimodzi, chifukwa mafuta amatha kuimbidwa mlandu;
Chifukwa cha malo owira kosiyanasiyana kwa mitundu yopanda tanthauzo la kuchepa kwa azetropic, Revield Revielnts ndi Afficy Revifints ndizosiyana kwenikweni ndikusiyana. Ngati Graifius Rifrants Rifirants adawonjezeredwa panthawiyi, kapangidwe kake kake kake kowonjezera zidzakhala zosiyana. Mwachitsanzo, gawo limodzi lokha lokhazikika limawonjezeredwa. Chotsani, ndiye madzi okhawo akhoza kuwonjezeredwa.
Ndiye kuti, kulibe kusinthasintha kwa mabifiki ophatikizidwa kuyenera kuwonjezeredwa ndi madzi, ndipo osakhala okhazikika a azetropic onse kuyamba ndi R4. Mtundu wamtunduwu umawonjezeredwa. Common non-azeotropic refrigerants are: R40, R401A, R403B, R404A, R406A , R407A, R407B, R407C, R408A, R409A, R410A, R41A.
As for other common refrigerants, such as: R134a, R22, R23, R290, R32, R500, R600a, the composition of the refrigerant will not be affected by the addition of gas or liquid, so it is convenient.
Mukawonjezera firiri, tiyenera kulabadira zotsatirazi:
(1) Onani thovu mugalasi lowoneka;
(2) Muzikwanitsa kuchuluka kwambiri komanso pang'ono;
(3) kuyeza compreskor pakalipano;
(4) Ganizirani jakisoni.
Kuphatikiza apo, ziyenera kudziwika ndikugogomezera kuti:
Nkhunda zopanda ulemu kwa azetropic ziyenera kuwonjezeredwa mu madzi. Mwachitsanzo, R410A firiji, kapangidwe kake ndi motere:
R32 (kutsutsana): 50%;
R125 (Pentafluoroeanhane): 50%;
Chifukwa malo owira a R32 ndi R125 ndi yosiyana, pomwe Cylinder Cylinder yatsala Mwinanso gawo lapamwamba la firiji ndi gawo la R32.
Chifukwa chake, ngati firiji ya gaseya yowonjezeredwa imawonjezeredwa, mufiriri yowonjezera si R410a, koma R32.
Chachiwiri, zovuta wamba zamadzimadzi
1. Kusamuka kwa Firiji
Kusungunuka kwa firiji kumatanthauza kudzikundikira kwa madzi okhazikika mu compressor crankse pomwe Compresser atatsekedwa. Malingana ngati kutentha mkati mwa conjor kumakhala kozizira kwambiri pakati pa compreor pakati pa compressor ndi wopandukayo amayendetsa firiji pamalo ozizira. Izi ndizotheka kupezeka nthawi yozizira. Komabe, kwa zowongolera mpweya ndi mapampu otentha, pomwe gawo lokhazikika lili kutali kwambiri ndi compressor, kusamuka kumachitika ngakhale kuti kutentha ndikokwera.
Dongosololi litatsekedwa, ngati silikuyatsidwa patangopita maola ochepa, ngakhale kulibe kusiyana, ngakhale palibe kusiyana kovuta, kusamukira kwina kumatha kuchitika chifukwa cha kukopeka kwa firiji ku firiji.
Ngati firiji yowonjezera yamadzi imasamukira mu crankcar ya comprescar ya comprescar, madzi othamanga kwambiri akayamba kufooka, monga kuwonongeka kwa cempreve, kuwononga kulephera ndikuwonongeka (firiji)
2. Madzi okwanira kusefukira
Valuweki akamalephera, kapena ma fanworator fan amalephera kapena amatsekedwa ndi zosefera mpweya, Referefirified Referrant ikusefukira ndikulowa compressor kudzera pa chitoliro cha madzi m'malo motaya nthula. Pamene unit ikuyenda, chifukwa cha madzi kusefukira kuphatikiza mafuta firiji, madera osunthira a compressor amavala, ndikupangitsa kuti chipangizocho chizikhalapo, potero chikuchititsa khungu kuti muchepetse mafuta. Pankhaniyi, ngati makinawo atsekedwa, zotsatira za kufinya kufinya zimachitika mwachangu, zomwe zimayambitsa madzi oyambiranso.
3. Kudya kwamadzi
Pamene madzi akumwa amachitika, kusula kachitsulo kwamveka kuchokera mkati mwa compression kumatha kumvedwa, ndipo zitha kutsagana ndi kugwedezeka kwamphamvu kwa compresser. Madzimadzi amadzimadzi, amatha kugwedezeka kwa ma Vamre, kulumikiza mpweya, kulumikiza rod kuthyola, crankshaft kuphwanya, ndi kuwonongeka kwa mitundu ina ya compressors. Kudzima kwamadzimadzi kumachitika pomwe madziwo amadzimafiriji amasunthira mu crankcase komanso kuyambiranso. M'magulu ena, chifukwa cha kapangidwe kazikulu kapena malo omwe muli zinthu, madziwo amadzimadzi amadziunjikira mu chitoliro kapena cholowa mu mawonekedwe a unit kapena liwiro lalitali kwambiri ndipo pothamanga kwambiri pomwe chipangizocho chimatsegulidwa. . Kuthamanga ndi kusowa kwa matenda a madziwo ndikokwanira kugonjetsedwa chitetezo cha compressor chilichonse ku Slam.

Mu seti ya kutentha pang'ono, pambuyo poti defrost nthawi, chipangizo chowongolera mafuta nthawi zambiri chimapangitsa kuti chikhalepo chifukwa cha kuchuluka kwa madzi firiji. Makina ambiri amapangidwa kuti alole firiji kukhazikika mu mzere woyamwa ndi woyamwa nthawi ya crornst, kenako ndikuyenda mu compresser croncy pa chiyambire kukakamiza mafuta, ndikupangitsa kuti chipangizochi chitetezeke chisagwire.
Nthawi zina kuchita chimodzi kapena ziwiri za chipangizo chowongolera mafuta sikungakhudze compression, koma mobwerezabwereza popanda kuthira mafuta bwino alephera. Chida choyendetsa chitetezo cha Mafuta nthawi zambiri chimawonedwa ngati cholakwika chaching'ono ndi wothandizira, koma ndi chenjezo lomwe Compressor lakhala likuyenda kwa mphindi zopitilira ziwiri popanda mafuta, ndipo njira zokwanira zimafunikira kukhazikitsidwa munthawi.
3. Kuthetsa vuto la Madzi Oyenera
Kuponderezana kopangidwa bwino, kokhazikika kwa firiji, zowongolera mpweya, ndi mapampu otentha ndizomwe amangopuma ndalama zambiri. Pofuna kupanga compresser yomwe imatha kuthana ndi mafuta ambiri okwanira komanso kuchuluka kwa kukula, kuphatikiza, kunenepa, kuchepa, phokoso, phokoso ndi mtengo ziyenera kuganiziridwa. Kupatula pazinthu zopangidwa, kuchuluka kwa madziwo mu compressor amatha kukhazikika, ndipo mphamvu yake imatengera zinthu zotsatirazi:
Ngati firiji ikuwonjezeka, imawonjezera ngozi ya compresser. Zifukwa zowonongeka zimatha kudziwa mfundo zotsatirazi:
(1) Chiwopsezo chachikulu kwambiri.
(2) Wolemba amachitidwa.
.
.
(5) Kusankha kolakwika kwa capillary.
(6) Kusankhidwa kapena kusintha kwa valavu yakukula sikulondola.
(7) Kusamukira ku Firiji.

Dongosololi litatsekedwa, ngati silikuyatsidwa patangopita maola ochepa, ngakhale kulibe kusiyana, ngakhale palibe kusiyana kovuta, kusamukira kwina kumatha kuchitika chifukwa cha kukopeka kwa firiji ku firiji.
Ngati firiji yowonjezera yamadzi imasamukira mu crankcar ya comprescar ya comprescar, madzi othamanga kwambiri akayamba kufooka, monga kuwonongeka kwa cempreve, kuwononga kulephera ndikuwonongeka (firiji)
