Ntu oyi n'ọdụ ụgbọ mmiri nlọghachi nke ihe nchekwa nchekwa oyi bụ ihe a na-ahụkarị na sistemụ refrigeration.N'ozuzu, ọ gaghị etolite ozugbo nsogbu usoro, na obere ntu oyi anaghị emekarị.Ọ bụrụ na ihe ntu oyi dị njọ karị, mgbe ahụ mkpa mbụ iji kpochapụ ihe kpatara ntu oyi
Mbụ, ndị Compressor ikuku laghachi n'ọdụ ụgbọ mmiri frosts
Ntu oyi na ntinye ikuku nloghachi na-egosi na ikuku ikuku nloghachi nke compressor dị oke ala.Kedu ihe ga-eme ka ikuku ikuku nke compressor dị ala dị ala?
Otu uka nke refrigerant, ọ bụrụ na ụda na nrụgide gbanwere, okpomọkụ ga-enwe ọrụ dị iche iche.Ọ bụrụ na okpomọkụ nloghachi nke compressor dị ala, ọ ga-egosipụtakarị nrụgide gas dị ala na nnukwu refrigerant nke otu olu n'otu oge.Mgbọrọgwụ nke ọnọdụ a bụ na refrigerant na-asọfe site na evaporator enweghị ike ịmịkọrọ okpomọkụ nke chọrọ site na mgbasawanye ya na uru okpomọkụ a kara aka.
Enwere ihe abụọ kpatara nsogbu a:
- The trotul mmiri refrigerant ọkọnọ bụ ihe nkịtị, ma evaporator enweghị ike ịmịkọrọ okpomọkụ nkịtị;
- na evaporator okpomọkụ absorption na-arụ ọrụ nke ọma, ma throttle refrigerant ọkọnọ dị ukwuu, ya bụ, refrigerant eruba bụ nke ukwuu, anyị na-aghọtakarị na refrigerant dị ukwuu.
Nke abụọ, n'ihi obere fluorine kpatara site na compressor nloghachi gas ntu oyi
1.n'ihi na eruba nke refrigerant dị nnọọ obere
Mgbasa obere refrigerant agaghị eji mpaghara evaporator dum, ọ ga-abụ naanị obere okpomọkụ na evaporator.N'ebe ụfọdụ, n'ihi obere refrigerant na mgbasawanye ngwa ngwa, ọnọdụ okpomọkụ dị n'ógbè ahụ dị ntakịrị, na ihe na-ekpo ọkụ na-ekpo ọkụ na-apụta.
Mgbe ntu oyi mpaghara gasịrị, n'ihi na e guzobere oyi akwa mkpuchi okpomọkụ n'elu nke evaporator na obere ọkụ na-ebufe na mpaghara a, a na-ebufe mgbasawanye refrigerant na mpaghara ndị ọzọ, ma jiri nwayọọ nwayọọ dum evaporator frosting ma ọ bụ icing phenomen, dum evaporator. kpụrụ a okpomọkụ mkpuchi oyi akwa, otú mgbasa ga-agbasa na compressor nloghachi ọkpọkọ na-eduga na compressor laghachi gas frosting.
2.n'ihi na obere ego nke refrigerant
Nrụgide ikuku dị ala na evaporator na-eduga na okpomọkụ evaporation dị ala, nke ga-eji nwayọọ nwayọọ na-eduga na condensation na evaporator iji mepụta oyi akwa mkpuchi okpomọkụ, ma nyefee ebe mgbasawanye na compressor nloghachi gas, na-eme ka compressor laghachi gas frosting.
Nrụgide ikuku dị ala na evaporator na-eduga na okpomọkụ evaporation dị ala, nke ga-eji nwayọọ nwayọọ na-eduga na condensation na evaporator iji mepụta oyi akwa mkpuchi okpomọkụ, ma nyefee ebe mgbasawanye na compressor nloghachi gas, na-eme ka compressor laghachi gas frosting.
Isi ihe abụọ a dị n'elu ga-egosi ntu oyi nke evaporator tupu compressor laghachi azụ ntu oyi.
N'ezie, n'ọtụtụ ọnọdụ maka ntu oyi onu, ọ bụrụhaala na ukpụhọde nke na-ekpo ọkụ gas uzo valvụ.Usoro a kapịrị ọnụ bụ imepe mkpuchi azụ azụ nke valvụ ikuku ikuku gas na-ekpo ọkụ, wee jiri eriri hex No.8 mee ka mkpụrụ na-agbanwe agbanwe n'ime elekere.Usoro mmezi adịghị ngwa ngwa.N'ozuzu, a ga-akwụsịtụ ya mgbe ọkara ọkara gachara, usoro ahụ ga-agba ọsọ ruo oge ụfọdụ iji hụ ọnọdụ ntu oyi tupu ị kpebie ma ọ ga-anọgide na-agbanwe.Mgbe ọrụ ahụ kwụsiri ike na ihe ntu oyi nke compressor na-apụ n'anya, mechie mkpuchi njedebe.
Nke atọ cylinder isi ntu oyi (dị njọ crankcase frosting)
Ihe na-akpata ntu oyi n'isi cylinder bụ nnukwu uzuoku uzuoku ma ọ bụ compressor mmiri na-ekpo ọkụ.Isi ihe kpatara nke a bụ:
- Ihe mmeghe nke valvụ mgbasawanye ọkụ dị oke ibu, na ntinye nke ngwugwu mmetụta okpomọkụ adịghị mma ma ọ bụ na-edozi ya, nke mere na mmetụta okpomọkụ dị elu na spool na-emeghe nke ọma.
valvụ mgbasawanye thermal na-eji superheat na oghere evaporator dị ka mgbama nzaghachi na-ebute mgbama mgbagha mgbe atụnyere ya na uru nke ikpo ọkụ enyere iji dozie mgbaba refrigerant n'ime evaporator.Ọ bụ onye na-ahụ maka nhazi nha nha kpọmkwem, nke na-ejikọta transmitter, regulator na actuator.
Dị ka ụdị nguzozi dị iche iche si dị, enwere ike kewaa valvụ mgbasawanye thermal na:
valvụ mgbasa ọkụ na-edozi ahụ nke dị n'ime;
valvụ mgbasa ọkụ na-agbanwe agbanwe nke mpụga.
A na-emepe valvụ mgbasawanye ọkụ ọkụ nke ukwuu, a na-etinye ngwugwu ihe mmetụta okpomọkụ na-ezighị ezi ma ọ bụ na-edozi ya, nke mere na okpomọkụ ahụ dị oke elu na spool na-emepe ihe na-adịghị mma, na-eme ka a na-amịnye nnukwu uzuoku mmiri mmiri n'ime compressor, na-akpata ya. ntu oyi na isi cylinder.
A na-emepe valvụ mgbasawanye nke thermal nke ukwuu, a na-etinye ngwugwu ihe mmetụta okpomọkụ na-ezighi ezi ma ọ bụ na-edozi ya, nke mere na mmetụta ahụ dị oke elu, a na-emeghe spool ahụ nke ọma, na-eme ka ọtụtụ uzuoku mmiri na-abanye na compressor, na isi cylinder na-agba oyi.
- Mgbe mmiri mmiri na-enye valvụ solenoid na-agbapụta ma ọ bụ kwụsị, a naghị emechi valvụ mgbasawanye nke ọma
Nnukwu mmiri mmiri refrigerant akwakọbara na evaporator tupu ịmalite.Ọnọdụ a dịkwa mfe ime ka compressor mmiri mmiri kụrụ!
- Nke ukwuu refrigerant na sistem
Mmiri mmiri dị na condenser dị elu, ebe a na-enyefe ọkụ na-ekpo ọkụ na-ebelata, nke mere na nrụgide nrụgide na-abawanye, ya bụ, nrụgide tupu valvụ mgbasawanye na-abawanye, ọnụọgụ refrigeration n'ime evaporator na-abawanye, mmiri mmiri refrigerant enweghị ike ikpochapụ kpamkpam. na evaporator, ya mere, compressor na-eku ume mmiri mmiri, ntutu isi cylinder dị oyi ma ọ bụ ọbụna oyi, ma nwee ike ime ka "mmiri mmiri na-egbu", na nrụgide evaporation ga-adị elu.
