Munyika yeHVAC (Heating, Ventilation, uye Air Conditioning), mashoma mabasa akakosha sekuiswa kwakaringana, disassembly, uye kugadzirisa kwepombi dzekupisa. Kunyangwe iwe uri nyanzvi yeruzivo kana DIY anofarira, kuve nekunzwisisa kwakazara kwemaitiro aya kunogona kukuchengetedza nguva, mari, uye kuwanda kwemusoro. Iyi nhanho-ne-nhanho gwara inokufambisa iwe kuburikidza nezvakakosha kugona kuisirwa, disassembly, uye kugadziriswa kwepombi dzekupisa, nekutarisa paR290 Monoblock Heat Pump.

Kuisa pombi yekupisa
order	content	kushanda chaiko
1	Tarisa iyo Installation Environment	Nzvimbo yekuisa inofanira kusangana nezvinodiwa zvinotsanangurwa mubhuku rekushandisa: Chikwata hachifaniri kuiswa munzvimbo yakavharwa yakachengetwa mukati meimba; hapafanirwe kuve nemvura yakavigwa isati yavigwa, magetsi, kana mapaipi egasi munzvimbo yekupinda mumadziro.
2	Unboxing Inspection	Chigadzirwa chacho chinofanira kunge chisina kuvharwa uye kuongororwa munzvimbo ine mhepo yakanaka; detector yeconcentration inofanira kugadzirirwa isati yasunungura chikwata chekunze; tarisa pane chero zviratidzo zvekudhumhana uye kana kutaridzika kuri kwemazuva ese.
3	Grounding Check	Simba remushandisi rinofanirwa kuve newaya yepasi; iyo unit's grounding wire inofanira kunge yakachengeteka yakabatana nesimbi casing; mushure mekuisa, tarisa ne multimeter kana voltage tester kuti uve nechokwadi chekudzika kwakakodzera. Tambo yemagetsi yakatsaurirwa inofanira kugadzikwa uye inofanira kunge yakanyatsobatanidzwa zvakananga kune socket yemagetsi yeyuniti.
4	Installation Foundation	Nheyo yakaomeswa ine vibration isolation pads inofanira kugadzwa semagumo anotakura mutoro.

Pa-Site Maintenance

A. I. Pre-Maintenance Inspection

Worksite Environment Check

a) Hapana refrigerant leakage inotenderwa mukamuri isati yashanda.

b) Kuenderera mberi kwemhepo kunofanirwa kuchengetedzwa panguva yekugadzirisa.

c) Kuvhura moto kana kupisa kwepamusoro-kupisa kunodarika 370 ° C (iyo inogona kubatidza moto) inorambidzwa munzvimbo yekuchengetedza.

d) Panguva yekugadzirisa: Vashandi vose vanofanira kudzima nharembozha.

Munhu mumwechete, single-unit, single-zone operation inokurudzirwa zvakasimba.

e) Poda yakaoma kana CO2 moto wekudzimisa moto (mumamiriro ekushanda) inofanira kuwanikwa munzvimbo yekuchengetedza.

Maintenance Equipment Kuongorora

a) Tarisa uone kuti midziyo yekugadzirisa yakakodzera firiji yepombi yekupisa. Ingoshandisa michina yehunyanzvi inokurudzirwa nemugadziri wepombi yekupisa.

b) Tarisa uone kana midziyo yekuona yefiriji yekuvuza yakagadziriswa. Iyo alarm yekumisikidza yekumisa haifanire kudarika 25% yeLFL (Lower Flammability Limit). Midziyo yacho inofanirwa kuramba ichishanda mukati memaitiro ese ekugadzirisa.

R290 Kupisa Pombi Kuongorora

a) Tarisa kuti pombi yekupisa yakanyatsodzika pasi. Ita shuwa kuenderera kwakanaka kwepasi uye yakavimbika grounding usati washanda.

b) Ona kuti magetsi epombi yekupisa akadzimwa. Usati wagadzirisa, bvisa magetsi uye bvisa ese electrolytic capacitors mukati meyuniti. Kana simba remagetsi richinyatsodiwa panguva yekugadzirisa, kuenderera mberi kwefiriji yekutarisa kudonha kunofanirwa kuitwa munzvimbo dzine njodzi kudzivirira njodzi dzinogona kuitika.

c) Ongorora mamiriro ezvinyorwa zvese uye mamaki. Tsiva chero mavara echenjedzo akakuvara, akasakara, kana asingaverengeki.

B. Kuonekwa kweLeak Pamberi Pa - Kugadziriswa kwesaiti

Ipo pombi yekupisa ichiri kushanda, shandisa inovuza detector kana concentration detector (pombi - suction type) inokurudzirwa nemugadziri wepombi yekupisa (ona kuti senitivity inosangana nezvinodiwa uye yakagadziridzwa, ine leak detector leakage rate ye1 g/gore uye concentration detector alarm concentration isingapfuure 25% yeLEL) yekutarisa air conditioner. Yambiro: Mvura yekuona yadeuka yakakodzera mafiriji mazhinji, asi usashandise zvinonyungudutsa zvine chlorine kudzivirira kukora kwepombi dzemhangura kunokonzerwa nekusangana kwechlorine nefiriji.
Kana pari kufungidzirwa kuti pabuda mvura, bvisa zvese zvinoonekwa zvinobvira moto panzvimbo yacho kana kudzima moto wacho. Uyewo, iva nechokwadi chokuti nzvimbo yacho ine mhepo yakanaka.
Zvikanganiso zvinoda welding yemukati refrigerant pombi.
Kukanganisa kunoda disassembly yefiriji system yekugadzirisa.

C. Mamiriro apo Kugadziriswa Kunofanira Kuitwa paSevhisi Center

Zvikanganiso zvinoda welding yemukati refrigerant pombi.
Kukanganisa kunoda disassembly yefiriji system yekugadzirisa.

D. Matanho Ekuchengetedza

Gadzirira zvishandiso zvinodiwa.
Bvisa firiji.
Tarisa iyo R290 yekusungwa uye bvisa iyo system.
Bvisa zvikamu zvekare zvakashata.
Chenesa refrigerant circuit system.
Tarisa iyo R290 concentration uye tsiva zvikamu zvitsva.
Bvisa uye uchaja neR290 refrigerant.

E. Misimboti Yekuchengetedza Panguva Yekuchengetedza Saiti

Paunenge uchichengetedza chigadzirwa, nzvimbo yacho inofanira kuva nemhepo yakakwana. Zvinorambidzwa kuvhara magonhi ese nemahwindo.
Marimi akavhurika anorambidzwa zvachose panguva yekugadzirisa, kusanganisira welding uye kuputa. Kushandiswa kwenharembozha kunorambidzwa zvakare. Vashandisi vanofanirwa kuziviswa kuti vasashandise marimi akavhurika pakubika, nezvimwe.
Munguva yekuchengetedza mumwaka wakaoma, apo hunyoro hwehukama huri pasi pe40%, matanho e-anti-static anofanira kutorwa. Izvi zvinosanganisira kupfeka zvipfeko zvedonje zvakachena, kushandisa anti-static zvishandiso, uye kupfeka magirovhosi edonje akachena pamaoko ese.
Kana kupisa kwefiriji kunopisa kunoonekwa panguva yekugadzirisa, pakarepo kumanikidzirwa kupinza mhepo kunofanira kutorwa, uye kunobva iyo inodonha inofanira kuvharwa.
Kana kukanganisa kwechigadzirwa kunoda kuvhura firiji system yekugadzirisa, inofanira kutakurwa kudzokera kuchitoro chekugadzirisa. Welding yemapombi efiriji uye mashandiro akafanana anorambidzwa zvachose panzvimbo yemushandisi.
Kana zvimwe zvikamu zvichidiwa panguva yekugadzirisa uye kushanya kwechipiri kunodiwa, pombi inopisa inofanira kudzorerwa kune yayo yepakutanga.
Iyo yose yekugadzirisa inofanirwa kuve nechokwadi chekuti firiji system yakachengetedzwa zvakachengeteka.
Paunenge uchipa pa-saiti sevhisi ine refrigerant cylinder, huwandu hwefiriji yakazadzwa mucylinder haifanire kudarika kukosha kwakatarwa. Kana silinda yakachengetwa mumotokari kana kuiswa panzvimbo yekumisikidza kana kugadzirisa, inofanirwa kunge yakamira yakadzikama, kure nezvinopisa, zvitubu zvemoto, zvitubu zvemwaranzi, uye midziyo yemagetsi.
