Kana zvasvika kumusimboti wekushanda wepombi yekupisa kwemhepo, zvinodikanwa kutaura aya mazwi akakosha: refrigerant, evaporator, compressor, condenser, heat exchanger, expansion valve, nezvimwe, izvo zvikamu zvakakosha zvepombi yekupisa. Pano isu tinosuma muchidimbu akati wandei akakosha matekinoroji emhepo sosi yekupisa pombi.
Refrigerant
Mafiriji haasi matorwa kwatiri. Inonyanya kuzivikanwa ndeye freon, iyo yakambobatanidzwa nekuparadzwa kwe ozone layer. Basa refiriji nderekutora uye kusunungura kupisa kuburikidza nekushandurwa kwemaitiro ayo emuviri mune yakavharwa system. Parizvino, mumhepo sosi yekupisa pombi unit, iyo yakajairika firiji iR22, R410A, R134a, R407C. Kusarudzwa kwemafiriji hakuna muchetura, haaputike, haaparadze simbi uye isiri-simbi, ine yakakwira yakadzika kupisa kwekubuda uye haina njodzi kune zvakatipoteredza.
compressor
Iyo compressor ndiyo "moyo" wepombi yekupisa unit. Iyo yakakodzera kupisa pombi compressor inogona kushanda zvakadzikama munzvimbo inotonhora ine tembiricha yakaderera ye - 25 ℃, uye inogona kupa 55 ℃ kana kunyange 60 ℃ mvura inopisa munguva yechando. Panyaya yekushanda kweiyo reaction compressor, tekinoroji yekuwedzera Enthalpy nejet inofanirwa kutaurwa. Kana tembiricha yakadzikira kupfuura - 10 ℃, iyo yakajairwa mhepo sosi yekupisa pombi yemvura hita yakaoma kushanda zvakajairika. Kushanda kwekushisa kwakadzika kune simba guru pakushanda kwekushanda kwemvura inopisa, uye zviri nyore kukuvadza zvikamu zvemvura inopisa. Pasi pemamiriro ekunze ekupisa, kuwedzera kweyekumanikidza reshiyo uye kusveta chaiko vhoriyamu kunotungamira kune yakanyanya kupisa tembiricha, kudzikisira kupisa simba, kuderedzwa kweyekuita kwekuita, uye kunyange kukuvara kwe compressor. Nokudaro, nokuda kwekushanda kwemamiriro ekushisa kwakadzika, tinogona kuwedzera mhepo kuti iwedzere enthalpy uye kaviri-nhanho compression muhurongwa hwekushanda hwekupisa pombi yemvura inopisa kuti ivandudze kushanda kwemaitiro.
