Isakhiwo nokuhlaziywa kwe Chiller

Okokuqala, izingxenye ze-chiller, i-compressor iyingxenye eyinhloko ye-chiller, futhi amandla e-kinetic ahlinzekwa yi-compressor enza i-chiller ikwazi ukujikeleza ngokuqhubekayo.

I-compressor ihlukaniswe yaba uhlangothi lokudonsa kanye nohlangothi lokukhipha. Uhlangothi lokumunca lumunca igesi eyisiqandisi kanti uhlangothi lokuphuma lukhipha igesi eyisiqandisi. Ekamelweni elisebenzayo le-compressor, i-compressor icindezela igesi efrijini elifakwe ohlangothini lokumunca, bese kuba igesi efrijini Izoba igesi epholile eshisa kakhulu nephezulu yokucindezela, esuke ikhishwe ekugcineni kokukhipha.

Ngemuva kokuphela kokukhipha i-oil separator, inhloso kanye nomsebenzi wayo ukuhlukanisa amafutha okugcoba afriziwe aqukethwe esiqandisini, bese kuba yi-condenser. Isiqandisi esihlanzekile ngemva kokuhlukaniswa kwamafutha singena epayipini le-condenser. Ngokusho kwama-chillers ahlukene, ahlukaniswe izigaba ezimbili: umoya opholile futhi opholile ngamanzi. Indlela yokwehlisa ukushisa kanye nendlela yokunciphisa izinga lokushisa yezikhonkwane ezipholisa umoya ihlukile kuleyo yezikhonsali ezipholiswa ngamanzi, kodwa zonke zikhona ukuze zifinyele.

Kungakhathaliseki ukuthi ipholile emoyeni noma ipholile ngamanzi, izinga lokushisa le-condenser livame ukuba phezulu kakhulu phakathi nenqubo yokusebenza naphakathi nenqubo ye-condensation, ngoba i-condenser iyisishintshi sokushisa, esisetshenziselwa ukushintshanisa ukushisa, futhi ukushisa kuyaphoqelelwa. ukugeleza emoyeni noma emjikelezweni wokupholisa Amanzi ayathathwa ukuze apholise isiqandisi.

Ngemuva kwenqubo yokunciphisa, isiqandisi siba uketshezi oluphansi lokushisa nokucindezela okuphezulu. Ukunciphisa i-throttling nokucindezela kuyadingeka ngezansi. Idivayisi yokunciphisa ukudonsa nokucindezela ivalvu yokunweba yama-chiller amaningi. Ukunemba, i-Thermal expansion valve.

I-valve yokwandisa okushisayo ingakwazi ukwahlulela usayizi wokuvula nokuvala ukuvuleka ngokusho kwenzwa yokushisa ekugcineni kwe-evaporator ye-chiller, bese ivumela uketshezi oluqandisiwe losayizi ofanele wokugeleza lungene kunqubo ye-evaporator, futhi lunciphise ingcindezi lapho. ukudlula ku-valve yokwandisa ukushisa, okungukuthi, i-Throttling kanye ne-depressurization.

Isiqandisi esiwuketshezi sizobe sesidlula ku-evaporator, sihwamuke futhi sibambe ukushisa ukuze sifinyelele isiqandisi, bese sihamba sisesimweni esiwuketshezi ukuze sibuyele ku-compressor (futhi sidlule nesihlukanisi se-gas-liquid).
