Nzira yekuziva uye kuwana nzvimbo chaiyo yekudonhedza mvura mukati mefiriji.

Nzira yekugadzirisa sei pombi inodonhedza mvura mufiriji?

Ma evaporator efiriji idzi anowanzo gadzirwa nezvinhu zvisiri zvemhangura, uye fungus inoonekwa mushure menguva yakareba yekushandiswa. Mushure mekutarisa zvikamu zvepombi zviri kudonhedza mvura, nzira yakajairika yekugadzirisa ndeyekutsiva zvikamu zvepombi zvakakuvara nezvitsva zve coil. Saka ungatarisa sei nzvimbo yekudonhedza mvura mufiriji usati watanga kugadzirisa zvikamu zvekutsiva?

 Nzira yekutonga sei kudonha kwefiriji mufiriji?

Kana firiji yakamira isiri kutonhora, mushure mekutanga muchina kwemaminitsi makumi maviri, bata pombi ine simba repamusoro wonzwa kupisa; panguva imwe chete, pombi ine simba repasi iri pedyo netembiricha yemumba (kazhinji inofanira kunge iri pa0°C, nechando chidiki), izvo zvinogona kuonekwa semhosva yefiriji. Refrigerant inodonhedza mvura.

 Nzira yekutsanangura chiyero chekubuda kwemvura?

Kazhinji, mafiriji anobuda mufiriji kana achidziya muzvinhu izvi: main evaporator, axiditive evaporator, door frame heating tube, built-in condenser nedzimwe nzvimbo.

 

 Maitiro ekuyedza mapaipi ane mweya wakamanikidzwa?

 

Nzira isina kuvimbika yekutarisa kana paine maburi anodonhedza mvura:

Mainjiniya ekugadzirisa asina ruzivo anobatanidza zvakananga pressure gauge ne process pipe ye compressor, achiwedzera mhepo yakaoma ku 0.68MPa, uye anoedza pressure ye outside pipe yefiriji. Nzira iyi dzimwe nguva haibatsiri, nekuti compressor, condenser, evaporator nezvimwe zvinhu zvepaipi zvakabatana pamwe chete, mapaipi anotaurirana, uye gasi rinokwana. Pane imwe nzvimbo mupaipi, pointer display value ye pressure gauge haizodziki munguva pfupi, kunyangwe kwemazuva anopfuura gumi. Saka, nzira iyi haina kuvimbika pakutsvaga maburi.

 

Nzira yakavimbika yekuona:

1. Kutanga tarisa kana pombi yakazaruka ichidonha; (pombi yakazaruka inogona kuongororwa kuti haina kudonha here nekushandisa sipo bubbles)

2. Kana pasina kubuda kwemvura mupombi yakavhurika, inguva yekusanganisa ne pressure gauge kuti utarise mamiriro epombi yemukati.

3. Welding pressure gauge papombi ine low pressure (Φ6mm, inonziwo intake pipe) uye paipi ine high pressure gas-out (Φ5mm) iri pedyo necompressor;

4. Cheka capillary iri kure ne5mm kubva pasefa, wobva wabatanidza magumo ecapillary yakachekwa ne solder;

5. Wedzera mhepo yakaoma kubva pachubhu yekushanda yecompressor kusvika pakumanikidzwa kwe0.68MPa, wobva wavhara chubhu yekushanda kuti mweya wemukati urambe uripo;

6. Mirira kuti tembiricha yenzvimbo dzese dzekusonera ienzane netembiricha yekunze (kweinenge awa imwe chete), wobva washandisa peni yekuisa chiratidzo panzvimbo yetsono yegeji pachivharo chegirazi chinoonekera chegeji yekumanikidza;

7. Ramba uchicherechedza kwemazuva maviri kusvika matatu (mamiriro acho ndeekuti tembiricha yemhepo haichinji zvakanyanya, zvikasadaro inokanganisa kukosha kwekumanikidzwa kwemhepo mukati mepombi);

8. Munguva yekutarisa, kana kukosha kwechiratidzo cheimwe yegeji dzekumanikidza kukadzikira, ndapota isa chiratidzo pachivharo chakajeka chedial;

9. Mushure mekuramba muchitarisa kwemazuva maviri kusvika matatu, kumanikidzwa kunodzikira zvakanyanya, izvo zvinoratidza kuti pombi yakabatana negeji yekumanikidzwa yabuda.

 

Ongorora zvakasiyana zvichienderana nekubuda kwemuchina we condenser uye kubuda kwemuchina we evaporator:

 

a)   Kana kukosha kwe pressure gauge mu evaporator chikamu kukadzikira, chinofanira kuongororwa zvakare muzvikamu.

Tarisa chikamu che evaporator nechikamu:

Bvisa ndiro yekumashure, paradzanisa evaporators dzepamusoro nedzepasi, isa pressure gauge, uye ramba uchiwedzera pressure test kusvika chikamu chaicho che evaporator chine maburi chaonekwa.

 

b)  Kana kuri kudonha kwekumanikidzwa kwechikamu che condenser, chikonzero chinofanira kuonekwa zvichienderana nechimiro chayo.

Kana zviri izvocondenser ine chimiro chakasungirirwa kumashure, chikonzero chikuru chingangove chekuboorwa kwepombi yedova pafuremu remusuwo.

Kana zviri izvocondenser yakavakirwa mukati, zvakakosha kuti tiongorore zvakare kuchinja kwehuwandu hwekumanikidzwa kwenzvimbo muzvikamu, uye kuisa gauge itsva yekumanikidza mupaipi kuti izvi zviitike.
